FIELD: radio engineering, communications.SUBSTANCE: cryptographic camera is stated, which represents a network video camera with a processor system of video data processing, comprising a video sensor with an analogue-to-digital converter for generation of video frames in digital form and in non-compressed condition for their transfer into a block of video processor for compression of video data and production of video frames in digital form and compressed condition, a controller of compressed video frames transfer into a network to a consumer and an adapter of connection to an autonomous or an outer sources of power supply. The cryptographic camera is equipped with a block of coding of compressed video frames, installed in a line of video data transfer into a controller, which is connected with a nonvolatile protected memory with secret keys, connected to the coding block and having a slot inside the body to record secret keys from an external source with the body open, and a sensor of body opening, connected to the autonomous source of power supply and via a controller connected to a block of data deletion in the specified memory with secret keys.EFFECT: enhanced protection of video data.1 dwg |
