| 摘要 |
The invention relates to a method for controlling the functional capability of an optical detection device (10), especially a camera and especially a surveillance camera for monitoring within a spatial range (B), characterised in that it comprises the following steps: a chronological sequence of test images (4) is obtained by a device for generating test images (3) and reproduced on a sensing element (1) of the detection device (10); the test images (4a) detected by the sensing element (1) are transmitted to an evaluating unit (5), and the evaluating unit (5) evaluates the detected test images (4a) with reference to variations in relation to the test images (4) thus generated. The detection device (10) can be automatically tested using the output of a fault indicator and/or disconnection of the monitored working machine. The invention also relates to a corresponding detection device.
