| 摘要 |
The invention relates to a detection device comprising a portable recording unit (CAM) for detecting a surrounding operating area by means of a sensor, a contactless communication interface (IF) for receiving identification data, and an analyzing unit (CTR) for analyzing the identification data and for activating the recording unit (CAM) dependent on the analysis. The advantage of the invention and the embodiments of the invention over conventional recording systems is characterized, among others, in that only work steps in a definable surrounding operating area are recorded and optionally only at specific times and/or periods of times without assistance from an operator. As an expandable system, not just audio and video streams can be recorded and analyzed but also additional surroundings data, such as temperature, humidity, etc., which can be used with respect to the audio and video data. |
