An old surveillance set-up

At the moment, I am in possession of a really old, monochromatic surveillance monitor and camera. Both the camera and monitor have their own microphones and speakers (low quality), with the camera speaker being the louder one. The monitor has multiple inputs for audio and video (red/yellow/white). The set-up itself is not very large, the monitor is smaller than an overhead project by a 25% or more.

Now my question is what do with it?
