Sure they work. A ceiling mount detector from Bosch recently helped Jade Alarm Co. and the local authorities apprehend an intruder at the Whatsoever Community Center in Kansas City. The intruder attempted to circumvent the Whatsoever Community Center’s first floor perimeter security by scaling an exterior wall and entering the facility on the second floor. Upon detecting motion on the second floor, the detector triggered an alarm to the control panel securing the premises. Jade dispatched local law enforcement personnel to the center. With the rapid detection of the intruder and response to the alarm, local authorities were able to arrive in time to observe the suspect beginning to leave the premises. As a result, the intruder returned to the community center and attempted to hide in the ceiling, where police promptly located and arrested the man.
