Facial recognition systems have proven to better the security of any building or business up and down the country. With the ability to match a human face from a digital image or a video frame against a database of faces, facial recognition CCTV is the ultimate security solution. 

The importance of facial recognition CCTV systems is clear for all to see, however, it may be less obvious as to how they work as well as being able to understand the benefits a facial recognition CCTV system can have for your business, site or building. Thankfully, this article explains everything you need to know. 

How do facial recognition CCTV systems work?

A facial recognition CCTV system is a camera or set of cameras that read a person’s facial features to grant or deny them access through a control point. It typically sits at the entrance to your business, or to a specific/access controlled room within your building.

Computer algorithms are used to instantly pick out specific, distinguishing features about a person’s face. These features include the distance between the eyes or shape of the chinworks and the CCTV system works with changes of facial expressions and even works when the person is wearing glasses, scarves or caps. These algorithms are then converted into a mathematical representation and compared to data on other faces collected in a face recognition database.

Facial recognition CCTV systems are an advanced piece of security technology that have the ability to work day or night, in any weather condition (including rain) or lighting. It includes live face detection so it is also able to differentiate between a real face and a photograph so it does not allow users to be impersonated using photographs or pictures.

The benefits of a facial recognition CCTV system

A facial recognition CCTV system is designed specifically for fast, discrete identification/registration of known or unknown individuals, whether in a large crowd at a stadium or festival or in public places such as airports, train stations or shopping centres. This ensures that you will receive the ultimate level of CCTV security available and have a system that can identify individuals even in the busiest of places. 

The toughest level of CCTV security

Facial recognition CCTV systems ensure maximum security for your business and/or building and guarantees that no unauthorised personnel are able to enter or exit your building. 

Whilst fingerprint readers and smart card access control systems require a smart card or a fingerprint to gain access or egress to a building, the facial recognition CCTV system does not. This ensures the safest working environment possible as it guarantees that only authorised personnel are able to gain access to your site/building. Facial recognition CCTV systems do not require smart cards to identify a person, meaning there are no smart cards to be passed around, lost or stolen and then replaced. 

Our line of facial recognition CCTV systems have the ability to create whitelists/blacklists at different entry points. People can be easily enrolled on these lists from photographs or video clips and do not have to be physically enrolled. 

Facial recognition CCTV systems are contact-free

It has never been more important to have a safe and hygienic place to work, socialise and be in large crowds following the COVID-19 outbreak. A facial recognition CCTV system ensures that no contact is to be made when people enter or exit a building or through a certain access point – maintaining a contactless entry system is vital and will help to stop the spread of viruses and illnesses.
