[origin: EP0137320A2] The device has at least one image pick-up apparatus (1 to 4) and a recording apparatus (6) for the image signals picked up. The output of the image pick-up apparatuses (1 to 4) is connected to a visual frequency/audio frequency converter (5) and to an audio-frequency tape recording unit (6) as recording apparatus, which stores the recorded signals for a certain time. The stored signals can be reproduced. After the storage time, the tape becomes free for new information. <IMAGE>
