There is disclosed a monitoring camera turning apparatus. An angle sensor continuously detects the turning angle of a turning shaft for turning a monitoring camera. Two detected angles are recorded as boundary limit angles in a recorder at the moment of generation of trigger signals. In a comparator, the recorded boundary limit angles are compared with the turning angle detected by the angle sensor at a moment. In accordance with results of this comparison, a switch device changes a direction of rotation of the turning shaft, thereby turning the monitoring camera in a monitoring range.

DETAILED DESCRIPTION It is an object of this invention to provide a monitoring camera turning apparatus in which the monitoring range can be easily changed, and a desirable monitoring range can be arbitrarily selected from two or more monitoring ranges preset, and the range of coverage by the monitoring camera exactly corresponds to a desired monitoring range.
To this end, according to the present invention, there is provided an apparatus for turning a monitoring camera comprising means for mounting the monitoring camera, means for detecting a turning angle of the mounting means, means for recording therein a pair of turning angles detected by the detecting means as monitoring boundary limit angles, means for comparing the recorded monitoring boundary limit angles with a turning angle detected by the detecting means at a moment, and means for changing a direction of turning of the mounting means in accordance with results of comparison by the comparing means.
