Abstract: A video and audio system for monitoring an area, particularly an area adjacent a door, is disclosed. The system includes a video and audio assembly adapted to be mounted to a door and a video and audio console spaced from the door. Opening of the door is controlled by an electric door strike operated from the console. The assembly is quite compact which facilitates mounting of the assembly to the door. The video camera includes a right angle optical system which contributes to the compactness of the assembly. Both the console and the assembly include audio elements which permit simultaneous two-way communication. A limited number of conductors none of which carry high voltage couple the assembly and the console.
