Cameras capable of recording video at 60 frames per second (fps) are becoming widely available in the security industry. It’s important to understand what 60-fps brings to the table for the security industry and how to leverage the technology for particular scenarios.

Capturing video at 60-fps represents a unique application. System integrators typically use much lower frame rates, ranging from 7- to up to 30-fps. The potential for an incident might only represent 1%, or less, of the time a camera is recording. However, when a significant event does occur, it’s better to record at a higher frame rate, because incidents such as a car accident, an altercation, or someone running away are usually only seconds long. Depending on the lighting environment, and the camera setup at that time, you either captured plenty of details or you didn’t.

Casino And Stadium Security

For example, in casinos, hands, money and chips move around quickly. If there’s a dispute, footage needs to be examined frame-by-frame at a resolution that provides exacting detail. For this reason, Las Vegas casinos require at least 30-fps for any cameras covering gaming action.

Another example is a stadium; if you have a lower frame rate of 10-fps, it might look good when all the seats are empty and there is very little motion. On game day, things can look different. If there is an altercation, at that frame rate, it becomes difficult to ascertain the actual sequence of events. The quality of what is captured in those brief moments is where 60-fps recording pays off with its increased resolution and crystal-clear image detail.

Can My Infrastructure Handle 60-fps?

Running multiple streams of 60-fps 24/7 will consume network resources and storage space at an exponential rate, which is difficult to justify for most organizations. For 60-fps recording to be practical, H.265 encoding and other compression techniques are necessary. With H.265, there is no requirement to upgrade a network infrastructure. H.265 does require a more capable workstation to decode, view and playback video, but most VMS systems utilize GPUs for decoding, so this is a non-issue for most installations.

The best way to reduce network and storage bandwidth is to teach the camera not to run at its maximum frame rate when there is no motion. The frame rate can drop to 5- to 4-fps if there is no motion or other activity, but as soon as there is a visual or audible trigger, the camera can dynamically switch to its highest frame rate. Having analytics in-camera makes this simple to setup and should be part of a camera’s profile.

Performance Vs. Frame Rate

A camera capable of 60-fps output is considered a high-performance camera. It might be more beneficial to put that performance to use enabling features other than pure 60-fps output. Cameras with the power to output 60-fps should also be able to process more data in parallel than regular cameras.

This means that a 60-fps camera could also be used to send out multiple streams at lower frame rates. You might decide on a 30-fps stream to the recorder, with a 15-fps profile feeding a live view, and another 15-fps stream going to a cellphone app. In this way, a 60-fps camera can offer tremendous flexibility in how its power and processing are used.

Always remember to tune cameras for nighttime use as well.
Shutter speeds are typically reduced at night to get more light onto a camera’s sensor

WDR (wide dynamic range) has the ability to combine multiple exposures into a single image to allow us to see in the shadows while not overexposing highlights. WDR can also halve your frame rate. A typical 30-fps sensor with WDR enabled has an effective frame rate of 15-fps for motion because of the duplicate frames being used for exposures. Starting with a 60-fps camera, customers can utilize WDR and still have an impressive 30-fps frame rate for an incredible quality image.

Optimising Equipment For Low-light Usage

Shutter speeds are typically reduced at night to get more light onto a camera’s CMOS sensor. The sensitivity of the sensor and the lens f-stop will come into play, but in general, if you force the camera to run at 60-fps at night, it’s going to produce a darker image than a 15-fps or 30-fps camera.

A camera set at 15-fps may also produce more of a ghosting effect on fast moving objects. Ultimately, it’s the customer’s individual use case that should dictate what is most important between luminance and clarity for moving objects.

A powerful 60-fps camera can deliver the best tradeoff between low-light performance and frame rate, giving end users the best possible solution available for their unique requirements. Many VMS solutions can tell cameras to switch profiles at certain times of the day to capture optimal images based on the environment and time of day.

Again, 60-fps cameras can offer the most flexibility across all scenarios. It’s important to remember that most cameras look good in daylight, and since 99% of installations happen in the daytime, always remember to tune cameras for nighttime use as well.

What New Technologies And Trends Will Shape Video Analytics?
What New Technologies And Trends Will Shape Video Analytics?

The topic of video analytics has been talked and written about for decades, and yet is still one of the cutting-edge themes in the physical security industry. Some say yesterday’s analytics systems tended to overpromise and underdeliver, and there are still some skeptics. However, newer technologies such as artificial intelligence (AI) are reinvigorating the sector and enabling it to finally live up to its promise. We asked this week’s Expert Panel Roundtable: What new technologies and trends will shape video analytics in 2021?

Tackling The Challenge Of The Growing Cybersecurity Gap
Tackling The Challenge Of The Growing Cybersecurity Gap

The SolarWinds cyberattack of 2020 was cited by security experts as “one of the potentially largest penetrations of Western governments” since the Cold War. This attack put cybersecurity front and center on people’s minds again. Hacking communication protocol The attack targeted the US government and reportedly compromised the treasury and commerce departments and Homeland Security. What’s interesting about the SolarWinds attack is that it was caused by the exploitation of a hacker who injected a backdoor communications protocol.  This means that months ahead of the attack, hackers broke into SolarWinds systems and added malicious code into the company’s software development system. Later on, updates being pushed out included the malicious code, creating a backdoor communication for the hackers to use. Once a body is hacked, access can be gained to many. An explosion of network devices What has made the threat of cyberattacks much more prominent these days has been IT's growth in the last 20 years, notably cheaper and cheaper IoT devices. This has led to an explosion of network devices. IT spending has never really matched the pace of hardware and software growth Compounding this issue is that IT spending has never really matched the pace of hardware and software growth. Inevitably, leading to vulnerabilities, limited IT resources, and an increase in IoT devices get more attention from would-be hackers. Bridging the cybersecurity gap In the author’s view, this is the main reason why the cybersecurity gap is growing. This is because it inevitably boils down to counter-strike versus counter-strike. IT teams plug holes, and hackers find new ones, that is never going to stop. The companies must continue fighting cyber threats by developing new ways of protecting through in-house testing, security best practice sources, and both market and customer leads. End-user awareness One of the key battlegrounds here is the education of end-users. This is an area where the battle is being won at present, in the author’s opinion. End-users awareness of cybersecurity is increasing. It is crucial to educate end-users on what IoT devices are available, how they are configured, how to enable it effectively, and critically, how to use it correctly and safely.

Will Airport Security’s Pandemic Measures Lead To Permanent Changes?
Will Airport Security’s Pandemic Measures Lead To Permanent Changes?

Travel volumes at airports have been increasing of late, although still below the 2.5 million or so passengers the Transportation Security Administration (TSA) screened every day, on average, before the pandemic. As passengers return, they will notice the airport security experience has changed during the pandemic – and many of the changes are likely to continue even longer. Need for touchless technology The lowest U.S. air travel volume in history was recorded last April, with approximately 87,500 passengers. As passenger traffic plummeted, the aviation community sought to explore the potential of new technologies to make security checkpoints more contactless and flexible when the traffic numbers return. The pandemic has seen an increase in touchless technology deployed in the screening area. Used for cabin baggage screening, Computed Tomography (CT) produces high-quality, 3-D images to enable a more thorough analysis of a bag’s contents. Imaging Technology Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method Enhanced Advanced Imaging Technology (eAIT), which uses non-ionizing radio-frequency energy in the millimeter spectrum, safely screens passengers without physical contact for threats such as weapons and explosives, which may be hidden under a passenger’s clothing. Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method.  AI algorithms Other innovations include an automatic screening lane, centralized image processing, and artificial intelligence (AI). Looking ahead, AI algorithms have the ability to clear most passengers and bags automatically, making the process smoother and freeing up staff to focus only on alarms. The pandemic’s need for contactless screening may accelerate the adoption of AI.   CAT machine Credential Authentication Technology (CAT) machines automatically verify identification documents presented by passengers during the screening process. The TSA continues to accept expired Driver’s Licenses and state-issued IDs for up to a year after expiration, based on the premise that license renewals may be delayed and/or more difficult during the pandemic. The REAL ID enforcement deadline was extended to Oct. 1, 2021.  Health precautions Checkpoint health precautions have been a part of the airport screening experience since early in the pandemic. Last summer, the TSA announced the “Stay Healthy. Stay Secure” campaign, which included requirements such as social distancing among travelers, ID verification without physical contact, plastic shielding installed at various locations, and increased cleaning and disinfecting. In January 2021, President Biden signed an Executive Order requiring travelers to wear face masks when in airports and other transportation facilities (to remain in effect until May 11). Checkpoint screening Clear is a privately owned company that provides expedited security that uses biometrics either a person’s eyes or face to speed along the process of getting people through checkpoints. TSA officers wear masks and gloves at checkpoints and may also wear eye protection or clear plastic face shields. The limits on allowable liquids a passenger may take on board were broadened to include a hand sanitizer container of up to 12 ounces, one per passenger in a carry-on bag. a paradigm shift Just as aviation security changed after 9/11, the COVID-19 crisis is expected to lead to a paradigm shift to create a safer and more secure environment. Measures were implemented so that passengers, staff and other stakeholders could have continued assurance and confidence in airports amid and after the pandemic.
