The high-performance Bosch VMD01 video motion detector has been specifically developed to suppress unwanted alarms in circumstances such as snow, rain, or when wind causes foliage movement, and other environmental changes. It is suitable for a wide variety of applications, protecting industrial properties, airports and government buildings, as well as warehousing operations, corrections facilities or museums. The VMD01 visualizes the surveillance scene. In case of an alarm, the alarm is signaled and displayed, while the alarm image sequence is stored for analysis by the operator. This offers the maximum possibility of undesired movement being detected and reduces the number of annoying, unwanted alarms.
