Dahua Technology Access control systems & kits

How can security system integrators not just survive but thrive in today’s IT-led market? The key seems to be in training. As increasingly more clients look to integrate access control with IT environments, they want integrators with the specialist skills to achieve this. For integrators that don’t invest in training, the risk is being left behind. Because many security system integrators aren’t providing specialist IT support, manufacturers are now offering services to make implementations and integrations easier. This isn’t a scalable or desirable option for many manufacturers though, they don’t want to become integrators. The result? Manufacturers will be pushed into developing products that can be integrated with IT networks off the shelf. And this isn’t necessarily the best option for end user, manufacturer or integrator. With a growing number of cloud-based security solutions, integrators also face the threat of clients opting for installation-only services. How security system integrators can survive and thrive today It’s not all doom and gloom for security system integrators though. To avoid becoming redundant, or being downgraded to simple access control installers, there’s lots you can do to strengthen your position. Listen carefully Many integrators are reluctant to do this, but it’s a great way to demonstrate the depth of your experience One of the first ways you can distinguish yourself from your competitors is by really listening to what your clients want and need. You can then translate this into a security or access control application tailored carefully to them. Many integrators are reluctant to do this, but it’s a great way to demonstrate the depth of your experience and product knowledge. It’s far superior to carrying out a standard implementation, which can leave clients feeling they’ve not been listened to or given good value. Up your IT knowledge TCP/IP has become the standard for communication between devices and central server applications in access control and security in general. So every technician now needs to know how to connect IP devices to networks and configure them in the central application. This is only the tip of the iceberg though, there’s so much more that integrators now need to be proficient in when it comes to IT. From understanding a client’s WAN, LAN and VPN networks to back-up systems, encryption technologies, key management and transparent communication. It’s also important to know how to integrate applications at server level, whether you’re integrating two or more security systems or a HR database. Most integrators have begun to invest in one or two IT experts, but this usually isn’t enough to meet clients’ needs. To really stay ahead, it’s crucial to invest more heavily in IT training and expertise. Choose your portfolio carefully When considering your portfolio, ensure you check the background of each product’s manufacturer Ideally, your portfolio should be small but rich, which is more difficult than it sounds. Choosing products that will scale easily is complex, and you need to consider the potential for increased functionality or connectivity as well as scalability. When considering your portfolio, make sure you check the background and outlook of each product’s manufacturer. You don’t want to select items that are likely to be discontinued in the near future, which can often happen after a manufacturer is acquired, for example. Get in the cloud In the security market, the mid and low segments are already shifting to cloud-based solutions that need neither integration nor IT skills. This leaves you with opportunities for just installation and maintenance services, where profit opportunities are reduced. An alternative is to begin selling cloud-based security services yourself to help you attract and retain clients for the long-term. Give clients added commercial value As competition increases and budgets shrink, offering added value, to new and existing clients, is a vital way to differentiate your business. This will help you to not just defend against competitors but to grow your business and increase your profitability. Configuring access control reports for clients is just one example. It’s relatively straightforward to do but provides really valuable insight into visitor flow. This can then enable them to, for example, staff reception adequately and provide sufficient catering, which all improves the experience for visitors and employees. Providing this kind of consultative service, instantly pushes you up the value chain. Stay agile and well informed To survive and grow as a security system integrator today, the upshot is that it’s crucial to keep pace with the market’s ever-changing trends, technology and client needs. And, to make sure you’re ready to adapt and give clients the services they want, it’s vital to give your people the in-depth training they need.

Back in the 1960s a lead engineer working in conjunction with the United States Navy for Lockheed’s Skunk Works team coined the acronym KISS, which translated to the design principle ‘keep it simple stupid’.  The KISS principle embraces the concept of simplicity, stating that most systems work best if they are kept simple rather than geared up to be more complicated. When it comes to physical security systems, this concept can also play a key element in its overall success. Secure work environments For years the tug of war in the security industry has pitted the need for a secure environment against the desire for technology that is convenient for users. However, finding a happy medium between the two has often seemed elusive. I believe you can design and have operational convenience at the same time as achieving high security" Jeff Spivey, a security consultant and the CEO of Security Risk Management, has this to say about it, “If there is an understanding of the security-related risks and their separate and/or collective impact on the organization’s bottom line business goals, a resolution can be reached.” Jeff also does not think that convenience and high security have to be opposing each other. He says, “I believe you can design and have operational convenience at the same time as achieving high security.” Importance of secure access control The premise is that for organizations and spaces to be truly secure, they must be difficult to access. So, by its very nature, access control is designed to be restrictive, allowing only authorized staff and visitors to access a facility or other secured areas inside. This immediately puts convenience at odds with security. Most people will tolerate the restrictive nature of a controlled entrance using badge, card or biometric because they understand the need for security. When that technology gets in the way of staff traversing freely throughout the facility during the course of a business day, or hindering potential visitors or vendors from a positive experience entering the building, they become less tolerant, which often leads to negative feedback to the security staff. Enhancing corporate security Security consultants like Spivey and security directors all stress that understanding the threats and risk levels of an organization will most likely dictate its physical security infrastructure and approach. All the technology in the world is useless if it is not embraced by those who are expected to use it and it doesn’t fit the culture of the organization. Once employees and customers are educated about what security really is, they understand that they're not losing convenience, they're gaining freedom to move safely from point A to point B. Converged data and information shape new access options Migration of physical access control systems to a more network-centric platform is a game-changer for security technologies The migration of physical access control systems to a more network-centric platform has been a game-changer for emerging security technology options. The expansion of the Internet of Things (IoT), Near-Field Communication devices powered by Bluetooth technology, and the explosion of converged information systems and identity management tools that are now driving access control are making it easier than ever before for employees and visitors to apply for clearance, permissions and credentials. Wireless and proximity readers Advancements in high-performance wireless and proximity readers have enhanced the user’s access experience when presenting credentials at an entry and expediting movement throughout a facility. A user is now able to access a secured office from street-level without ever touching a key or card. Using a Bluetooth-enabled smartphone or triggering a facial recognition technology, they enter the building through a security revolving door or turnstile. A total building automation approach adds extra convenience, as well as seamless security, when access technology is integrated into other systems like elevator controls. A total building automation approach adds extra convenience and seamless security How to Meet Security Concerns at the Entry While security managers are charged with providing their facilities the maximum level of security possible, there is always the human element to consider. But does the effort to make people comfortable with their security system ecosystem come at a cost? Does all this convenience and the drive to deliver a positive security experience reduce an organization’s overall levels of security? And if so, how can we continue to deliver the same positive experience including speed of entry – while improving risk mitigation and threat prevention? Door entrances, barriers Users can slip through the door or turnstile barriers while they are still open after a credentialed individual has gone through Let’s examine some of the various types of entrances being used at most facilities and the security properties of each. With some entrance types, there is the possibility for security to fall short of its intended goals in a way that can’t be addressed by access control technology alone. In particular, with many types of doors and barriers, tailgating is possible: users can slip through the door or turnstile barriers while they are still open after a credentialed individual has gone through. To address this, many organizations hire security officers to supervise the entry. While this can help to reduce tailgating, it has been demonstrated that officers are not immune to social engineering and can often be “talked into” letting an unauthorized person into a facility. Deploying video cameras, sensors Some organizations have deployed video surveillance cameras or sensors to help identify tailgaters after the fact or a door left open for longer than rules allow. This approach is not uncommon where facilities have attempted to optimize throughput and maintain a positive experience for staff and visitors. Security staff monitoring the video feeds can alert management so that action can be taken – but this is at best a reactive solution. It does not keep the unauthorized persons from entering, and so is not a totally secure solution. Optical turnstiles, speedgates Security staff should carefully evaluate its facility’s needs and consider the technology that is built into the door itself Security staff should carefully evaluate its facility’s needs and consider the technology that is built into the door itself. Not all security entrances work the same way. And, there will always be a balance between security and convenience – the more secure the entry, the less convenient it is for your personnel and visitors to enter your facility. For example, it takes more time to provide 2-factor authentication and enter through a mantrap portal than to provide only one credential and enter through an optical turnstile or speedgate. Perimeter protection So, it is an important first step to determine what is right at every entrance point within and around the perimeter. Remember that convenience does not equate to throughput. Convenience is the ease and speed of entry experienced by each individual crossing that threshold, while throughput relates to the speed at which many individuals can gain access to the facility. A more convenient entry makes a better first impression on visitors and is good for overall employee morale. Throughput is more functional; employees need to get logged in to begin their workday (and often to clock in to get paid), and they quickly become frustrated and dissatisfied when waiting in a long line to enter or exit the premises. Considering form and function when designing a security entrance can ensure that those requiring both high-security and convenience are appeased.

Imagine a home surveillance camera monitoring an elderly parent and anticipating potential concerns while respecting their privacy. Imagine another camera predicting a home burglary based on suspicious behaviors, allowing time to notify the homeowner who can in turn notify the police before the event occurs—or an entire network of cameras working together to keep an eye on neighborhood safety. Artificial Intelligence vision chips A new gen of AI vision chips are pushing advanced capabilities such as behavior analysis and higher-level security There's a new generation of artificial intelligence (AI) vision chips that are pushing advanced capabilities such as behavior analysis and higher-level security to the edge (directly on devices) for a customizable user experience—one that rivals the abilities of the consumer electronics devices we use every day. Once considered nothing more than “the eyes” of a security system, home monitoring cameras of 2020 will leverage AI-vision processors for high-performance computer vision at low power consumption and affordable cost—at the edge—for greater privacy and ease of use as well as to enable behavior analysis for predictive and preemptive monitoring. Advanced home monitoring cameras With this shift, camera makers and home monitoring service providers alike will be able to develop new edge-based use cases for home monitoring and enable consumers to customize devices to meet their individual needs. The result will be increased user engagement with home monitoring devices—mirroring that of cellphones and smart watches and creating an overlap between the home monitoring and consumer electronics markets. A quick step back reminds us that accomplishing these goals would have been cost prohibitive just a couple of years ago. Face recognition, behavior analysis, intelligent analytics, and decision-making at this level were extremely expensive to perform in the cloud. Additionally, the lag time associated with sending data to faraway servers for decoding and then processing made it impossible to achieve real-time results. Cloud-based home security devices The constraints of cloud processing certainly have not held the industry back, however. Home monitoring, a market just seven years young, has become a ubiquitous category of home security and home monitoring devices. Consumers can choose to install a single camera or doorbell that sends alerts to their phone, a family of devices and a monthly manufacturer’s plan, or a high-end professional monitoring solution. While the majority of these devices do indeed rely on the cloud for processing, camera makers have been pushing for edge-based processing since around 2016. For them, the benefit has always been clear: the opportunity to perform intelligent analytics processing in real-time on the device. But until now, the balance between computer vision performance and power consumption was lacking and camera companies weren’t able to make the leap. So instead, they have focused on improving designs and the cloud-centric model has prevailed. Hybrid security systems Even with improvements, false alerts result in unnecessary notifications and video recording Even with improvements, false alerts (like tree branches swaying in the wind or cats walking past a front door) result in unnecessary notifications and video recording— cameras remain active which, in the case of battery powered cameras, means using up valuable battery life. Hybrid models do exist. Typically, they provide rudimentary motion detection on the camera itself and then send video to the cloud for decoding and analysis to suppress false alerts. Hybrids provide higher-level results for things like people and cars, but their approach comes at a cost for both the consumer and the manufacturer. Advanced cloud analytics Advanced cloud analytics are more expensive than newly possible edge-based alternatives, and consumers have to pay for subscriptions. In addition, because of processing delays and other issues, things like rain or lighting changes (or even bugs on the camera) can still trigger unnecessary alerts. And the more alerts a user receives, the more they tend to ignore them—there are simply too many. In fact, it is estimated that users only pay attention to 5% of their notifications. This means that when a package is stolen or a car is burglarized, users often miss the real-time notification—only to find out about the incident after the fact. All of this will soon change with AI-based behavior analysis, predictive security, and real-time meaningful alerts. Predictive monitoring while safeguarding user privacy These days, consumers are putting more emphasis on privacy and have legitimate concerns about being recorded while in their homes. Soon, with AI advancements at the chip level, families will be able to select user apps that provide monitoring without the need to stream video to a company server, or they’ll have access to apps that record activity but obscure faces. Devices will have the ability to only send alerts according to specific criteria. If, for example, an elderly parent being monitored seems particularly unsteady one day or seems especially inactive, an application could alert the responsible family member and suggest that they check in. By analyzing the elderly parent’s behavior, the application could also predict a potential fall and trigger an audio alert for the person and also the family. AI-based behavior analysis Ability to analyze massive amounts of data locally and identify trends is a key advantage of AI at the edge The ability to analyze massive amounts of data locally and identify trends or perform searches is a key advantage of AI at the edge, for both individuals and neighborhoods. For example, an individual might be curious as to what animal is wreaking havoc in their backyard every night. In this case, they could download a “small animal detector” app to their camera which would trigger an alert when a critter enters their yard. The animal could be scared off via an alarm and—armed with video proof—animal control would have useful data for setting a trap. Edge cameras A newly emerging category of “neighborhood watch” applications is already connecting neighbors for significantly improved monitoring and safety. As edge cameras become more commonplace, this category will become increasingly effective. The idea is that if, for example, one neighbor captures a package thief, and then the entire network of neighbors will receive a notification and a synopsis video showing the theft. Or if, say, there is a rash of car break-ins and one neighbor captures video of a red sedan casing their home around the time of a recent incident, an AI vision-based camera could be queried for helpful information: Residential monitoring and security The camera could be asked for a summary of the dates and times that it has recorded that particular red car. A case could be made if incident times match those of the vehicle’s recent appearances in the neighborhood. Even better, if that particular red car was to reappear and seems (by AI behavior analysis) to be suspicious, alerts could be sent proactively to networked residents and police could be notified immediately. Home monitoring in 2020 will bring positive change for users when it comes to monitoring and security, but it will also bring some fun. Consumers will, for example, be able to download apps that do things like monitor pet activity. They might query their device for a summary of their pet’s “unusual activity” and then use those clips to create cute, shareable videos. Who doesn’t love a video of a dog dragging a toilet paper roll around the house? AI at the Edge for home access control Home access control via biometrics is one of many new edge-based use cases that will bring convenience to home monitoring Home access control via biometrics is one of many new edge-based use cases that will bring convenience to home monitoring, and it’s an application that is expected to take off soon. With smart biometrics, cameras will be able to recognize residents and then unlock their smart front door locks automatically if desired, eliminating the need for keys. And if, for example, an unauthorized person tries to trick the system by presenting a photograph of a registered family member’s face, the camera could use “3D liveness detection” to spot the fake and deny access. With these and other advances, professional monitoring service providers will have the opportunity to bring a new generation of access control panels to market. Leveraging computer vision and deep neural networks Ultimately, what camera makers strive for is customer engagement and customer loyalty. These new use cases—thanks to AI at the edge—will make home monitoring devices more useful and more engaging to consumers. Leveraging computer vision and deep neural networks, new cameras will be able to filter out and block false alerts, predict incidents, and send real-time notifications only when there is something that the consumer is truly interested in seeing. AI and computer vision at the edge will enable a new generation of cameras that provide not only a higher level of security but that will fundamentally change the way consumers rely on and interact with their home monitoring devices.

Dahua Technology USA Inc., a provider of advanced, video-centric, smart IoT solutions, has introduced a new selection of 5MP IP cameras in its cost-efficient Lite Series, incorporating Smart Motion Detection (SMD) technology for ease of set-up, improved accuracy, and fewer false alarms.  Smart Motion Detection (SMD)  SMD uses an advanced algorithm to differentiate human and vehicular shapes within a scene and send alarms only when a person or vehicle is detected. SMD can be enabled with just one click, allowing the camera to analyze all motion within its view. The camera then filters motion-activated objects depending on what the user wants to see, making searches faster. “Compared with traditional motion detection where lights, animals, rain, and tree movement tend to cause false alarms, Dahua’s SMD feature gives the user highly accurate motion detection with fewer false alarms. No more annoying alarms with useless information,” remarked Jennifer Hackenburg, Senior Product Marketing Manager at Dahua Technology USA. SMD N53A series cameras The SMD N53A series cameras can be paired with Dahua N52 and N54 Series NVRs with upgraded firmware The SMD N53A series cameras can be paired with Dahua N52 and N54 Series NVRs with upgraded firmware to take advantage of the complete SMD solution. With this solution, users can tailor real-time push notifications according to what’s relevant to them and conduct quick target searches based on object classification, date and time. The SMD feature will expand to other models later this year. Quick Target Search, a playback feature, extracts and classifies images of humans and vehicles from video data, making it easy for users to review and retrieve historical information. The SMD cameras are well-suited for environments where limited resources mean fewer onsite security guards. Integrated with IR and Starlight technology The SMD N53A Lite Series offers fixed and vari-focal options in eyeball, dome and bullet-style form factors. These cameras include additional, advanced features that further maximize users’ Return on Investment (ROI), such as Starlight technology for ultra-low-light scenes, True Wide Dynamic Range (120dB), integrated IR, and perimeter protection for customized intrusion detection and tripwire functionality. Additionally, the Smart H.265+ codec reduces bandwidth and storage requirements without compromising image details. “The new SMD cameras represent advanced edge technology that truly reduce false alarms and provide peace of mind,” added Hackenburg. “We’re pleased to be able to provide SMD based on customer needs and help them bring additional value to the end users.”

GSX 2019 got off to a jaunty start Tuesday. The show was humming with activity much of the day, and most exhibitors said they were pleased with the numbers and types of potential customers visiting their booths. There seemed to be less emphasis on product introductions than at the ISC West show in the spring (although there is much that is on the new side), while the trend toward system sales is continuing. Here's a review of Day 1 from the show floor. Dahua continues to educate market  “Traffic-wise, the show is better than last year,” observed Tim Shen, Director of Marketing at Dahua Technology USA, at midday on Tuesday. “We met more people from Latin America,” he added. Shen theorized that Chicago is at the center of a larger territory of customers than last year’s location (Las Vegas).Dahua’s presence at the show makes a statement: “We’re still here" Dahua has faced some negative publicity in the last year since they were banned from procurement by U.S. government customers by the National Defense Authorization Act (NDAA). Dahua’s presence at the show makes a statement, says Shen. The statement is “We’re still here.” Shen said only one visitor to the Dahua booth even mentioned the NDAA on the first day of the show, and the visitor was misinformed about the provisions and implications of the law. “There is a lot of misinformation,” he says. “We need to continue to educate the market.” Facial recognition, video metadata, and people counting New at the show is the Dahua Analytics+ line of cameras that feature more in-depth analysis of data such as facial attributes, video metadata, and people counting. For example, the cameras can identify 128 points in a face, with an additional 256 attributes analyzed by the back-end recorder. Analysis can provide information such as age and gender, which can help a retailer analyze the demographics of their customers, for instance. Dahua is also adopting some of its consumer line of products for sale through the commercial channel. These include a flood light camera, a 2-megapixel WiFi camera and a doorbell camera. The products might be used outside of a retail store, for example, to complement Dahua commercial cameras that are used inside the store, says Shen. Dahua previewed a new multi-sensor camera that also includes a speed dome. The multi-sensor component combines eight views, each 2 megapixels, for a total of 16 megapixels. Below the multi-sensor camera is mounted a speed dome that can zoom in on regions of interest in the larger multisensor view. The camera will be launched in the fourth quarter. The show was humming with activity much of the day, and most exhibitors said they were pleased with the numbers and types of potential customers visiting their exhibits ACRE reports continued North American growth “The industry’s momentum will continue to grow,” predicted Joe Grillo, Principal of ACRE. New areas such as cloud and mobile credentialing have the fastest growth rate, but are starting from a much smaller base, he said, so momentum in those categories will take time.ACRE sees continued rapid growth with no slowdown in the North American market Grillo noticed the first morning of GSX was busy, although there was a bit of a lull at midday. In terms of the business outlook, Grillo sees continued rapid growth with no slowdown in the North American market, although there have been some negative elements creeping into the outlook in Europe. Cybersecurity concerns in access control I caught up with Grillo at the booth promoting RS2, a Munster, Ind., access control company that Acre acquired last May. It is the only Acre company that is exhibiting at GSX. RS2 is one of two access control companies acquired by Acre in the last year — the other was Open Options, Addison, Texas. Grillo said the two acquired companies are complementary, especially in terms of their sales channels and geographic strengths. Although both are national companies, RS2 tends to be stronger in the Midwest, while Open Options sales emphasis is centered in Texas and emanates to the rest of the country. Concerns about vulnerabilities are a growing issue in access control, said Grillo, and more large endusers are conducting penetration testing of systems. The industry should welcome the scrutiny, he added. Cybersecurity also represents an business opportunity in access control, noted Grillo. Concerns about the vulnerabilities of legacy technologies such as 125Khz proximity cards and the Wiegand protocol will likely accelerate the pace of companies upgrading their access control systems There seemed to be less emphasis on product introductions than at the ISC West show in the spring (although there is much that is on the new side) Eagle Eye Networks and cloud-based VMS Ken Francis of Eagle Eye Networks had already realized some new client opportunities during the first day of the show, although he was not optimistic at the outset. In contacting potential clients to meet at the show, he had heard that many were not attending. Among Eagle Eye Networks’ news at the show is full integration of body-cams into their cloud-based video management system. “It’s the most unique thing happening from a video management perspective,” Francis said. Previously, if someone needed a video clip from a body cam, they had to use a separate software system. Five years from now, at least 80 percent of all VMS systems will be cloud-managed" Francis continues to be bullish on the subject of cloud adoption of video management and made a bold prediction: “Five years from now, at least 80 percent of all VMS systems will be cloud-managed.” Eagle Eye Networks is doing its part with “rocket growth” that is reflected in an increase of company employees from 27 to 165 or so. Economies of scale have enabled Eagle Eye Networks to lower subscription prices by up to 45 percent. Genetec's release self-service PIAM system Many of the “new” products at GSX 2019 are slight variations on what was introduced at ISC West last spring. An exception is Genetec’s introduction of ClearID, a self-service physical identity and access management (PIAM) system that enforces security policies while improving the flow of people within the organization. The new system is integrated with the Genetec's Security Center Synergis access control system. PIAM systems have historically been customizable, complex to install and costly, which is why a lot of companies have not used a system. Genetec’s differentiator is that it is an off-the-shelf, out-of-the-box solution for a broader base of customers. “We scanned the market and found a lack of off-the-shelf identity management systems,” said Derek Arcuri, Product Marketing Manager, Genetec. “Targeting the mid-market, we are providing an accessible, ready-to-go cloud-based system that is ‘baked’ for the average company but can be integrated and expanded to include other systems.” The trend toward system sales at the show is continuing ClearID will simplify operation for the security department, which was previously tasked with a lot of administrative work in response to various departments. ClearID “pushes down” the authority to use the system to stakeholders (such as IT and/or facilities directors) and provides  a system they can use themselves without involving security. “It empowers stakeholders and employees to work directly through the system rather than going through security,” says Arcuri. “It gives employees access based on stakeholder policies and improves the flow of people through an organization. The security director is relieved of administrative work and can work on ‘real’ security.” I saw some other things today, too, which I will share in a future GSX article... And more about the show tomorrow.

Video surveillance is used for more than just safety and security: users are discovering that high-resolution images and user-friendly features make surveillance cameras a valuable asset for all sorts of applications. A cattle ranch in Manatee County, Florida found that a Dahua PTZ was the perfect way to observe eagles without disturbing their habitat. Dahua PTZ Cameras  When Hurricane Irma pummeled Florida in 2017, Victoria and Nicholas, a pair of American bald eagles, watched their nest get destroyed. Undeterred, they began building a new nest in a tree right next to the old one. The ranchers on whose property the eagles lived were so inspired by this show of dedication that they decided to install cameras nearby to share the eagles’ story with the world. They reached out to Jens Buff, security consultant with Rapid Security Solutions, for support, and he contacted Dahua. Dahua donated a 4MP 30x IP PTZ, which was mounted to a tree in order to observe the nest up close. Dahua donated a 4MP 30x IP PTZ, which was mounted to a tree in order to observe the nest up close But disaster struck yet again! In 2018 “an unnamed storm, unexpected and unseasonable, blew through our area with pounding rain and ferocious winds,” stated the Eagle Country YouTube page. “Sadly, the eagles’ nest was blown to the ground in pieces again! We wondered if they would relocate, but this was Nicholas and Victoria. The very next day they began to rebuild. The cameras we placed after Irma were not destroyed and we are able to watch this incredible story continue.” Smart IR And Day/Night Surveillance Dozens of YouTube videos, as well as a live feed, give viewers a rare glimpse into the day-to-day lives of these majestic birds. Whether they’re incubating eggs, eating dinner, cleaning house, or fending off intruders, their activities are captured in clear video both day and night. The camera’s true day/night IR cut filter and Smart IR allow for crisp nighttime images without “whitening out” as the eagles get close to the camera. True WDR preserves the image in the direct sunlight that’s unavoidable at the top of a tree in the Sunshine State. The easy-to-use PTZ features let the ranchers follow the eagle’s actions without bothering them by manually repositioning the camera. “Dahua’s PTZ was the perfect choice to view one of life’s most beautiful creations living in nature,” Mr. Buff remarked.
