I believe this would have been used as a security camera way back in the time of EAIJ format video tape recorders.
This link has some good info on cameras and recorders of that era.

The video jack on the rear is just that. If your camera works and you conect the video jack on the camera to the yellow video input jack on your TV (you will have to make a cable to do that) you should get picture.
Back when that camera was made video cables used the conector that is on your camera, then when consumer video equipment became relatively affordable they started using the RCA conectors you see on video equipment today.
Hope this helps.
