ABSTRACT:
In order to combine an optimal deterrent effect with monitoring possibilities a monitoring installation includes a plurality of rotatable monitoring units, which units have two parallel slot shaped openings. These openings extend along a bottom circular sector. A camera lens and a loudspeaker arranged in a louvre are located in every slot shaped opening. These are traversable at least over part of the extent of the circular sector. A potential thief is given the impression of an uninterrupted monitoring. He is deferred further by the loudspeakers. These can at the same time be used for transmitting alarms, announcements or customer information.
