Access control systems
Many organizations which have the need to enhance security do so by limiting access to their facilities to authorized personnel.
A significant challenge for access control systems is to detect when an unauthorized person tries to enter the secured area together with an authorized person, a so-called tailgating situation. Such a situation is very difficult to detect with a conventional security camera, since light conditions may vary, resulting in shadows which can be misinterpreted as persons or objects. In addition, there is often inadequate contrast in the image between the person and the background seen by a common surveillance camera.
The above challenges can be met with an SR4000 camera from MESA. The solution consists of a single camera mounted on the ceiling of the airlock. With its compact size, the camera is very discrete and there is minimal impact to the structural design of the airlock.
Compared to conventional security cameras that only see 2D contours of an object, a TOF camera can sense the 3D shape, enabling very robust detection of persons and objects, making it almost impossible to deceive the access control system.
