VOCORD FaceControl is a non-cooperative face capturing and recognition system.
Non-cooperativeness means that a system doesn’t require system-man cooperation in any way in order to facilitate recognition of that person. Therefore, VOCORD FaceControl system is used successfully for facial recognition purposes in crowded areas – subway stations, railroad stations, stadiums, concert halls and other public areas where people can not be forced to interact with the biometric identification system.
Facial recognition system VOCORD FaceControl:
Public safety ensuring
VOCORD FaceControl is successfully utilized for security purposes in public areas. For that end, the sites are equipped with specialized facial recognition cameras. The check points are deployed at the entries and exits or in narrow passages (underground and overhead walkways, corridors, etc).
Unlimited number of databases can be connected to the system. For example, databases of local police, Federal Security Service of Russia and court marshals. At appearance of the person in search, an operator receives a notice specifying the matched database and comments if any.
Using VOCORD FaceControl systems, operators can not only run searches in the existing databases but also populate them. In respect to safety of sports and other facilities, petty offenders often visit the same areas repeatedly. VOCORD FaceControl system allows to receive a portrait reference database containing high quality photos of all individuals passing the check point. Using this database you can on an operational basis and with a high probability detect an suspicious individual next time at his/her appearance at the site.
Using the above approach, you can make the best use of the system in large-scale retail chains for the purposes of operational notification to security guards of appearance of shop breakers.
This permits to search the photo of person of interest against portrait reference database . The system analyzes the archive automatically and detects all events of appearance of the person of interest at the facility.
To ensure access control for secure facilities and special protected sites, the standard access control system based on personal proximity-cards can be insufficient. Using VOCORD FaceControl facial recognition system you can increase control level. Special facial recognition cameras are installed at the check points, and the system is integrating with a standard access control system.
The system will grant access upon receipt of positive results of matching against the “Whitelist”. Otherwise, the system will notify a security officer of presence of a stranger. “Reinforcement” of a security system by integrating with a facial recognition technology not only raises an access control level but also offers additional protection against unauthorized persons entering building using valid proximity cards owned by others.
VOCORD FaceControl system contributes to investigations of accidents as it stores the photos of all people which passed the check point. In case of an unexpected accident, you can always look through the portrait reference database over a particular period of time and find out persons who visited the facility.
VOCORD FaceControl system operation can be organized in an “interfaceless mode”. For example when integrated with an access control system, VOCORD FaceControl just confirms or declines access and registers all access facts in the access control system log; at that, an operator uses only the access control system interface.

Non-cooperative facial recognition
Unlike a number of biometric systems requiring accurate positioning of the person’s face in relation to the camera, VOCORD FaceControl works in a completely noncooperative mode. In other words, the subject should not take up a position in the camera view – the system captures faces of subjects in a crowd or pedestrian flow, the subjects may be completely unaware that they are under video control.
This allows VOCORD FaceControl to work effectively not only as an access control system but also as a security system in the areas difficult to ensure cooperation of people and recognition systems – subway stations, railroad stations, stadiums, cinemas, stores and other public areas.
Video cameras with an inbuilt face detection
VOCORD FaceControl system uses specialized video cameras VOCORD NetCam4 K-series with an inbuilt face detection and capturing algorithm. Such camera transfers video stream containing only captured facial images. This allows:
VOCORD NetCam4 cameras are specifically developed for facial recognition systems. Except algorithms of adaptation to video analytics tasks, these cameras support multicast broadcasting and interfaces with peripheral equipment, for example, with access control system controllers.
High recognition accuracy
It helps to achieve very high recognition accuracy. The average probability of the correct recognition by VOCORD FaceControl system in real conditions is above 90 %.
Compliance with biometric standards
VOCORD FaceControl is a one of a number of facial biometric systems which comes up to IEC 19794-5-2006 “Automatic identification. Biometric identification. Biometric data interchange formats. Facial image data.” for quality of digital video data suited for execution of automatic biometric identification by facial image.
VOCORD FaceControl has a geographically distributed architecture. In small-scale systems the whole installation may be deployed on a single server. In case of a geographically distributed system, each software module have be installed on a separate server and there can be an unlimited number of servers inside the installation network.
The system is available in 2 variants: (1) variant based on VOCORD NetCam4, K-series cameras with inbuilt facial detection and capturing algorithm, and (2) variant based on VOCORD NetCam4, D-series cameras.
