El Paseo South Gate is a large shopping center, located in South Gate, California. Guests visit to take advantage of the shopping, food, and entertainment amenities while enjoying the stunning modern architecture and large outdoor murals.

El Paseo South Gate was relying on an analog surveillance system that was installed in the late ‘90s. The system was becoming increasingly unreliable and could no longer meet the organization’s modern-day security needs. 

The center tried replacing the cameras and the DVRs, however, this did not provide the ideal level of quality that was needed. El Paseo South Gate wanted to modernise its surveillance capabilities and deploy a new IP security solution.


Several challenges need to be addressed before implementing the new IP security system. El Paseo South Gate wanted to deploy IP cameras to get complete surveillance coverage throughout the interior of the mall and in outdoor areas, including parking lots and the parking garage. 

Many desired endpoint locations were well beyond the 328ft (100m) reach limitation of standard Ethernet switches, and installing IDF closets would add cost and complexity to the project.

Innovative IP solution

The customer was concerned with the high cost, complexity, and ripping out the Coax and replacing it with CAT6/Fiber

A Coax-based infrastructure supported the existing analog camera system. The customer was concerned with the potentially high cost, complexity, and disruption from ripping out the Coax and replacing it with a CAT6/Fiber backbone. 

Additionally, there was minimal cable route location information due to a lack of documentation from the original installation. Many environments, including the parking garage, had concrete walls, making the task of re-cabling even more difficult. 

The customer needed an innovative solution to overcome its IP modernisation challenges.

CLEER24 long reach PoE switch

OC Tech Innovations (OCTI) met with NVT Phybridge at ISC West, one of the largest North American security events, and discovered the CLEER24 long reach PoE switch

The enterprise-grade CLEER24 switch is an EoC (Ethernet over Coax) innovation that delivers Ethernet and PoE+ over any new or existing Coax cable with up to 6,000ft (1,830m) reach. That’s 18-times the reach of a standard Ethernet switch. 

OCTI connected with the local NVT Phybridge team and arranged a proof-of-concept to test the solution.

Robust system 

After a few simple setup steps, the CLEER24 transformed the customer’s existing and proven Coax-based infrastructure into a robust IP backbone for the new IP cameras. 

OCTI and NVT Phybridge worked together to deliver several pre-sale demonstrations for the customer to ensure it was the right solution for their needs. 

El Paseo South Gate was impressed with the solution and decided to move forward with the modernisation initiative.

Benefits of the new solution

1) Reaches hard to see spots

OCTI used the CLEER24 switch to enable IP cameras, including those in hard-to-reach places

El Paseo South Gate was completely satisfied with the entire experience. OCTI used the CLEER24 switch to enable several of the IP cameras, including those in hard-to-reach places, such as the parking garage. 

The CLEER24 switch was especially helpful when connecting IP cameras on the fifth level of the parking garage”, said Behzad Faridnia, Founder and Chief Innovator, OC Tech Innovations.

These runs were originally done via encased conduit without pull strings. If new cabling was needed, this would have required a new surface-mounted conduit system to be installed.” 

Reduced infrastructure costs for better ROI 

OCTI estimates that El Paseo South Gate saved approximately $465,000 in infrastructure costs using the NVT Phybridge CLEER24 switch; a total cost reduction of 71%. 

We are confident that this would not have been possible without the NVT Phybridge EoC product line,” said Behzad. 

The client is very satisfied as they were able to avoid costly trenching and unsightly conduit runs to install these new cameras.”

2) Simple and fast deployment

By leveraging the NVT Phybridge CLEER24 switch and avoiding the rip-and-replace process, the total deployment time was reduced by two months. “The NVT Phybridge solutions were easy to deploy,” said Behzad. 

Their wide range of adapters allowed us to include multi-sensor and PTZ cameras (pan-tilt-zoom) with higher Power over Ethernet requirements while auto-negotiating PoE within the same system from the same switch.” The slim form factor of the CLEER24 switch was easily incorporated into the customer’s existing rack and ensured plenty of open rack space for future expansion. 

The NVT Phybridge extenders are slim and fit easily into the pole mount and enclosures where space is at a premium,” said Behzad. “The NVT Phybridge extenders are far slimmer than the other brands on the market.”

3) Simple LAN design

OCTI was able to consolidate all cable runs to the customer’s main server room without the need for costly intermediate distribution frame (IDF) closets. 

This significantly reduced network costs for El Paseo South Gate and simplified network design as we were able to utilize all original conduit runs, removing the need for costly trenching,” Behzad commented.

4) Superior performance at greater lengths

OCTI and El Paseo Plaza plan to add IP-based annunciators using the existing Coax cable runs and the EC4 adapter

The NVT Phybridge EC4 adapter provides the ability to connect up to four IP devices over one long-run Coax cable. OCTI and El Paseo Plaza plan to add IP-based annunciators using the existing Coax cable runs and the EC4 adapter.

When assessing the customers’ existing infrastructure, OCTI found that many cable runs had several splices with BNC couplers. “At first, we were concerned that these splices would degrade the overall signal,” said Behzad. 

However, the signal had no issue passing through, even when with an 8-splice run.” The CLEER24 switch was able to support high-demand cameras at great lengths, even in the toughest environments. “Even when connecting the longest cable run, we had no issues getting the IP camera online,” commented Behzad.

5) Physical network segmentation

OCTI was able to maintain a physically separate network for the new IP camera system. This will enhance network security, reduce ongoing costs, and simplify LAN management. 

For security reasons, the system is “air-gapped” with the Video Management System (VMS) acting as the middleman between the surveillance network and the local LAN network for other devices”, said Behzad. “The NVT Phybridge admin portal was easy to configure for alignment with the surveillance-only subnet.”

Pre and post-sale support

Pre- and post-sales support were beyond the level we expected in terms of detail and personalisation,” said Behzad. 

This was a breath of fresh air as far too many companies disappear once the project is won. We appreciated the support and look forward to adding NVT Phybridge as our go-to solution for IP modernisation projects. We are already exploring the use of other products for other challenges we are facing”.

What You Need To Know About Open Source Intelligence (OSINT) For Emergency Preparedness?
What You Need To Know About Open Source Intelligence (OSINT) For Emergency Preparedness?

Have you ever stopped to consider the volume of new data created daily on social media? It’s staggering. Take Twitter, for instance. Approximately 500 million tweets are published every day, adding up to more than 200 billion posts per year. On Facebook, users upload an additional 350 million photos per day, and on YouTube, nearly 720,000 hours of new video content is added every 24 hours. While this overwhelming volume of information may be of no concern to your average social media user posting updates to keep up with family and friends, it’s of particular interest to corporate security and safety professionals who are increasingly using it to monitor current events and detect potential risks around their people and locations—all in real-time. Meet the fast-paced and oft-confusing world of open-source intelligence (OSINT). What is Open Source Intelligence (OSINT)? The U.S. Department of State defines OSINT as, “intelligence that is produced from publicly available information and is collected, exploited, and disseminated promptly to an appropriate audience to address a specific intelligence requirement.” The concept of monitoring and leveraging publicly available information sources for intelligence purposes dates back to the 1930s. The British Broadcast Corporation (BBC) was approached by the British government and asked to develop a new service that would capture and analyze print journalism from around the world. Monitoring and identifying potential threats Originally named the “Digest of Foreign Broadcast, the service (later renamed BBC Monitoring which still exists today) captured and analyzed nearly 1.25 million broadcast words every day to help British intelligence officials keep tabs on conversations taking place abroad and what foreign governments were saying to their constituents. OSINT encompasses any publicly accessible information that can be used to monitor and identify potential threats Today, OSINT broadly encompasses any publicly accessible information that can be used to monitor and identify potential threats and/or relevant events with the potential to impact safety or business operations. The potential of OSINT data is extraordinary. Not only can it enable security and safety teams to quickly identify pertinent information that may pose a material risk to their business or people, but it can also be captured by anyone with the right set of tools and training. OSINT for cybersecurity and physical threat detection Whether it be a significant weather event, supply chain disruptions, or a world health crisis few saw coming, the threats facing organizations continue to increase in size and scale. Luckily, OSINT has been able to accelerate how organizations detect, validate, and respond to these threats, and it has proved invaluable in reducing risk and informing decision-making – especially during emergencies. OSINT is typically shared in real-time, so once a situation is reported, security teams can then work on verifying critical details such as the location or time an incident occurred or provide the most up-to-date information about rapidly developing events on the ground. They can then continue to monitor online chatter about the crisis, increasing their situational awareness and speeding up their incident response times. OSINT applications OSINT can help detect when sensitive company information may have been accessed by hackers  Severe weather offers a good example of OSINT in action. Say an organization is located in the Great Plains. They could use OSINT from sources like the National Weather Service or National Oceanic and Atmospheric Administration (NOAA) to initiate emergency communications to employees about tornado warnings, high winds, or other dangerous conditions as they are reported. Another common use case for OSINT involves data breaches and cyber-attacks. OSINT can help detect when sensitive company information may have been accessed by hackers by monitoring dark web messaging boards and forums. In 2019, T-Cellphone suffered a data breach that affected more than a million customers, but it was able to quickly alert affected users after finding their personal data online. OSINT is a well-established field with countless applications. Unfortunately, in an ever-changing digital world, it’s not always enough to help organizations weather a crisis. Why OSINT alone isn’t enough? One of the core challenges with leveraging OSINT data, especially social media intelligence (SOCMINT), is that much of it is unstructured and spread across many disparate sources, making it difficult to sort through, manage, and organize. Consider the social media statistics above. Assuming a business wanted to monitor all conversations on Twitter to ensure all relevant information was captured, it would need to both capture and analyze 500 million individual posts every day. Assuming a trained analyst spent just three seconds analyzing each post, that would amount to 1.5 billion seconds of labor—equivalent to 416,666 hours—just to keep pace. While technology and filters can greatly reduce the burden and help organizations narrow the scope of their analysis, it’s easy to see how quickly human capital constraints can limit the utility of OSINT data—even for the largest companies. Challenges with OSINT OSINT data collection includes both passive and active techniques, each requiring a different level of effort and skill Additionally, collecting OSINT data is time-consuming and resource-intensive. Making sense of it remains a highly specialized skill set requiring years of training. In an emergency where every second count, the time required to sift through copious amounts of information takes far longer than the time in which an organization must take meaningful action to alter the outcome. Compounding the issue, OSINT data is noisy and difficult to filter. Even trained analysts find the need to constantly monitor, search, and filter voluminous troves of unstructured data tedious. Artificial intelligence and machine learning have helped weed through some of this data faster, but for organizations with multiple locations tasked with monitoring hundreds or thousands of employees, it’s still a challenging task. Adding to the complexity, collecting OSINT data isn’t easy. OSINT data collection includes both passive and active techniques, each requiring a different level of effort and skill. Passive vs Active OSINT Passive OSINT is typically anonymous and meant to avoid drawing attention to the person requesting the information. Scrolling user posts on public social media profiles is a good example of passive OSINT. Active OSINT refers to information proactively sought out, but it often requires a more purposeful effort to retrieve it. That may mean specific login details are needed to access a website where information is stored. Lastly, unverified OSINT data can’t always be trusted. Analysts often encounter false positives or fake reports, which not only take time to confirm accuracy, but if they act on misinformation, the result could be damage to their organization’s reputation or worse. So, how can companies take advantage of it without staffing an army of analysts or creating operational headaches? A new path for OSINT Organisations can leverage the benefits of OSINT to improve situational awareness and aid decision-making Fortunately, organizations can leverage the benefits of OSINT to improve situational awareness and aid decision-making without hiring a dedicated team of analysts to comb through the data. By combining OSINT data with third-party threat intelligence solutions, organizations can get a cleaner, more actionable view of what’s happening in the world. Threat intelligence solutions not only offer speed by monitoring for only the most relevant events 24/7/365, but they also offer more comprehensive coverage of a wide range of threat types. What’s more, the data is often verified and married with location intelligence to help organizations better understand if, how, and to what extent each threat poses a risk to their people, facilities, and assets. In a world with a never-ending stream of information available, learning how to parse and interpret it becomes all the more important. OSINT is a necessary piece to any organization’s threat intelligence and monitoring system, but it can’t be the only solution. Paired with external threat intelligence tools, OSINT can help reduce risk and keep employees safe during emergencies and critical events.

Baltimore Is The Latest U.S. City To Target Facial Recognition Technology
Baltimore Is The Latest U.S. City To Target Facial Recognition Technology

The city of Baltimore has banned the use of facial recognition systems by residents, businesses and the city government (except for police). The criminalization in a major U.S. city of an important emerging technology in the physical security industry is an extreme example of the continuing backlash against facial recognition throughout the United States. Facial recognition technology ban Several localities – from Portland, Oregon, to San Francisco, from Oakland, California, to Boston – have moved to limit use of the technology, and privacy groups have even proposed a national moratorium on use of facial recognition. The physical security industry, led by the Security Industry Association (SIA), vigorously opposed the ban in Baltimore, urging a measured approach and ‘more rational policymaking’ that preserve the technology’s value while managing any privacy or other concerns. Physical security industry opposes ban In such cases, it is local businesses and residents who stand to lose the most" “Unfortunately, an outright ban on facial recognition continues a distressing pattern in which the clear value of this technology is ignored,” said SIA’s Chief Executive Officer (CEO) Don Erickson, adding “In such cases, it is local businesses and residents who stand to lose the most.” At the national level, a letter to US President Biden from the U.S. Chamber of Commerce Coalition asserts the need for a national dialog over the appropriate use of facial recognition technology and expresses concern about ‘a blanket moratorium on federal government use and procurement of the technology’. (The coalition includes Security Industry Association (SIA) and other industry groups.) The negativity comes at a peak moment for facial recognition and other biometric technologies, which saw an increase of interest for a variety of public and business applications, during the COVID-19 pandemic’s prioritization to improve public health hygiene and to promote ‘contactless’ technologies. Prohibition on banks, retailers and online sellers The ordinance in Baltimore prohibits banks from using facial recognition to enhance consumer security in financial transactions. It prevents retailers from accelerating checkout lines with contactless payment and prohibits remote online identity document verification, which is needed by online sellers or gig economy workers, according to the Security Industry Association (SIA). At a human level, SIA points out that the prohibition of facial recognition undermines the use of customized accessibility tools for disabled persons, including those suffering with blindness, memory loss or prosopagnosia (face blindness). Ban out of line with current state of facial recognition Addressing the Baltimore prohibition, the Information Technology and Innovation Foundation reacted to the measure as ‘shockingly out of line with the current state of facial recognition technology and its growing adoption in many sectors of the economy’. Before Baltimore’s decision to target facial recognition, Portland, Oregon, had perhaps the strictest ban, prohibiting city government agencies and private businesses from using the technology on the city’s grounds. San Francisco was the first U.S. city to ban the technology, with Boston, Oakland; Cambridge, Massachusetts; and Berkeley, California, among others, following suit. Police and federal units can use biometrics Unlike other bans, the Baltimore moratorium does not apply to police uses Unlike other bans, the Baltimore moratorium does not apply to police uses, but targets private uses of the technology. It also includes a one-year ‘sunset’ clause that requires city council approval for an extension. The measure carves out an exemption for use of biometrics in access control systems. However, violations of the measure are punishable by 12 months in jail. The law also establishes a task force to evaluate the cost and effectiveness of surveillance tools. Transparency in public sector use of facial recognition Currently, the state of Maryland controls the Baltimore Police Department, so the city council does not have authority to ban police use of facial recognition, which has been a human rights concern driving the bans in other jurisdictions. A measure to return local control of police to the city could pass before the year lapses. SIA advocates transparency in public-sector applications of facial recognition in identity verification, security and law enforcement investigative applications. SIA’s CEO, Don Erickson stated, “As public sector uses are more likely to be part of processes with consequential outcomes, it is especially important for transparency and sound policies to accompany government applications.”

What Are The Security Challenges Of Protecting Critical Infrastructure?
What Are The Security Challenges Of Protecting Critical Infrastructure?

Many of us take critical infrastructure for granted in our everyday lives. We turn on a tap, flip a switch, push a button, and water, light, and heat are all readily available. But it is important to remember that computerized systems manage critical infrastructure facilities, making them vulnerable to cyber-attacks. The recent ransomware attack on the Colonial Pipeline is an example of the new types of threats. In addition, any number of physical attacks is also possibilities. We asked this week’s Expert Panel Roundtable: What are the security challenges of protecting critical infrastructure?
