Abstract: A remote controlled television monitoring system for day and night monitoring includes a camera unit in the form of a housing having first and second cameras. The first camera principally monitors during daylight conditions; while the second camera monitors during low light or night conditions. The second camera preferably has a high low light sensitivity. Both of the cameras have automatic iris over ride for manual control of the camera iris. Each of the cameras optionally has an azimuth generator to indicate angular position of the camera. An adjustable zoom lens is coupled to each of the cameras. In one aspect, a light intensifier is coupled between the lens and the second camera for intensifying light received by the second camera. The light intensifier preferably has internal automatic brightness control.

Abstract: A face badge reader is located in proximity with a lockable closure allowing access to a predetermined area and includes a first camera for scanning an individual's face, a receptacle for receiving an identification badge bearing the individual's photograph and a second camera for scanning the badge. The video signals are transmitted to a remotely located monitor for viewing comparison. The face badge reader receives inputs from sensor switches and push buttons and includes control devices for energizing a door strike release mechanism associated with the closure for unlocking the closure. A remotely located controller controls the selective unlocking of the closure and camera selection. The face badge reader and the controller include transmitters and receivers which communicate via digitally encoded control signals.

Abstract: A remote controlled television monitoring system for both day and low light level condition monitoring. The monitoring system includes a dual channel camera unit, a passive transmitter unit, and a receiver unit interposed between the transmitter unit and the remotely located camera unit. The transmitter provides control signals to a video control circuit in the receiver unit which controls the positioning of the camera unit as well as the camera lens functions. The dual channel camera unit is mounted on a pan-tilt unit; and includes a day-light camera, a low-light camera, a light intensifier for the low-light camera, and a channel control circuit. The channel control circuit provides for automatic channel switching in response to light intensity variations. This circuit also provides automatic control of the light intensifier during low-light operation.
