| 摘要 |
The present invention is directed to a method and system for controlling operation of an anti-masking system that detects tampering with a motion detection system. The control system may include a selective adjustment mechanism for adjusting a sensitivity level of the anti-masking system and a trigger mechanism for triggering the selective adjustment mechanism upon occurrence of an event to raise the sensitivity level of the anti-masking system. The control system may additionally include a timer for extending the raised sensitivity level for a predetermined time period beyond the occurrence of the event. The control system may operate in conjunction with a motion detection system that includes at least one motion detection sensor for detecting motion.
