CCTV Facial Recognition

Powerful new technologies like Machine Learning and Artificial Intelligence have recently been developed to offer an entirely new level of security. Video capture and recording solutions today can record facial images and compare them with incredible accuracy. And Hikvision is right there at the forefront of this exciting new horizon in protecting our communities, our loved ones, and our property. 

There are many ways to use Facial Recognition to keep people safe, enhance business operations, as well as improve our everyday lives with optimised services. Here’s a glimpse into how it works and how we can use it to make the world safer each time it’s needed.

Law Enforcement

This technology serves best where suspect identification is most critical, including government and diplomacy buildings; borders and customs areas; travel nodes such as air and sea ports, just to name a few. Also, law enforcement personnel will find a more efficient way to investigate incidents with advanced footage retrieval using recognition capabilities and vehicle traits analysis algorithms.

Time & Attendance Reports

Now there is a better way to track attendance. Based on facial recognition technology, this new method is quicker, safer, and more accurate. Thanks to this technology, employees no longer need to remind themselves to carry ID cards all the time, and professors will no longer need to take roll one by one. A great tool at Educational Campuses, Factories, and at Events and Conferences.

VIP Recognition

Loyal VIP customers are enormously valuable to commercial entities, but service staff cannot always identify them immediately. Intelligent facial recognition cameras, however, can provide unique opportunities that were previously unavailable. When customers choose to participate in VIP programs, marketing promotions or other incentives, facial recognition technology will give retailers accurate tools to identify VIPs and loyal customers so staff can provide the right kind of service at the right time. Hikvision facial recognition can create new possibilities to optimize your next marketing program. 

Blacklist Alarm

Using the Blacklist Alarm provides extra help to law enforcement personnel to identify known suspects in designated areas and secure public safety. For commercial customers, a list of interesting people can be used in a similar way to trigger attention and action needed if ‘unwanted’ people are detected at Sports Venues, Malls and Hotels, just to name a few. 

How Recognition can Prevent Crime and Improve Security

Why Facial Recognition?
Public security threats along with increasing security demands from users continually pressure security manufacturers to create ever improving technologies. International news constantly peppers the public consciousness with reminders of present dangers. The public wants to know – can these events ever be prevented?

For everything from safe city projects to home protection, developments are underway all over the world, with their relative obstacles. Safeguarding family members, homes, property, and vehicles are the most common applications using these emerging technologies. But the number of video surveillance cameras used in any given application, with their various networks and demanding resolutions, has increased dramatically with an equal increase in challenges. An ability to fast-track through oceans of data to find the small amount that is actually critical is now in high demand.

On the security side of video intelligence technologies, increasing customer safety has been the primary driving factor. On the business side of video intelligence technologies, increasing customer satisfaction has been the primary driving factor. Here, both service and safety are critical. Facial recognition technologies will not only address these issues, but will improve on our abilities to overcome the challenges involved. More than just speed up or enhance current methods, facial recognition will open up new avenues for security and new realms of data wherever it’s needed. 

Security Industry Difficulties & Requirements
Identifying suspects during post-event investigation poses many complicated difficulties. Challenges include everything from reviewing footage from scores of cameras, comparing two face images of the same person with a 10-year age gap, and extracting the 5% (or less) of useful information from massive amounts of data, to implementing pre-event alarms to prevent incidents and managing increased video storage challenges due to increased resolutions. And likely a lot more, too.

These obstacles can prove paralyzing for standard video surveillance systems, even with up-to-date equipment. The sheer amount of information being processed bogs down system hardware. This is where more data-heavy solutions are needed, precipitating the development of deep learning and artificial intelligence products. Along with those new technologies, facial recognition is undoubtedly one of the most important right now. 

Common Insufficiencies in Facial Recognition Solutions
Conventional intelligent video surveillance carries very strict requirements for a scene’s background. For human facial recognition process, two key steps are required. The first one is Feature Extraction, where the features are designed by humans and are always subjective. This method performs well in very specific environments, and subtle changes in lighting, environment, etc., sacrifice accuracy. The second step is “Classification Learning”, which uses shallow learning and analysis. Far from ideal, the results here directly restrict the breadth and depth of intelligent applications.

Deep-Learning Benefits for Intelligent Video Surveillance
Deep learning is intrinsically different from other algorithms. The way it solves the insufficiencies of traditional algorithms is encompassed in a few concepts. 

First, From “Shallow” to “Deep” 
The algorithmic model for deep learning has a much deeper structure than that of traditional algorithms. Sometimes, the number of layers can reach over a hundred, enabling it to process large amounts of data in complex classifications. Deep learning is very similar to the human learning process, and has a layer-by-layer feature-abstraction process. Each layer will have different “weighting,” and this weighting reflects on what was learned about the images’ “components.” The higher the layer level, the more specific the components.  Simulating the human brain, an original signal in deep learning passes through layers of processing; next, it takes a partial understanding (shallow) to an overall abstraction (deep) where we can perceive the object. 

Second, From “Artificial Features” to “Feature Learning.” 
Deep learning does not require manual intervention but relies on a computer to extract features by itself. This way it is able to extract as many features from the target as possible, including abstract features that are difficult or impossible to describe. The more features there are, the more accurate the recognition and classification will be. Some of the most direct benefits that deep learning algorithms can bring include achieving comparable or even better-than-human pattern recognition accuracy, strong anti-interference capabilities, and the ability to classify and recognize thousands of features.

With deep learning technology, the average accuracy of facial recognition increases significantly. Hikvision has demonstrated its ability to advance ahead of the competition. Its advantages in Artificial Intelligence in security have come about by having its own excellent algorithm development team and using the most powerful GPUs in our computer platforms. The results include winning in multiple International Deep Learning algorithm competitions, such as ImageNet, PASCAL VOC, the MOT Challenge, and more. 

Achieving the best results come from a combination of having the right hardware and developing algorithms that can perform the computational requirements. Hikvision has the industry’s first data computing platform with best-in-class hardware, and completely independent algorithm team.
