Home Alarm & Travel Protection Monitor
Detects intrusion by sensing body heat up to 30' away. Whenever motion is detected, it provides either a "Ding dong" chime, or it can emit a piercing 80db siren. Includes a 10-15 sec exit delay. 80-degree coverage. Includes adjustable wall bracket. No wires required (operates on 3 AA alkaline batteries, not included). Low-battery warning.
This is a "set & forget" stand-alone device that is designed to operate independantly and provide an audible response whenever it is triggered. (It could be retrofitted to interface with an alarm system if the user is familiar with electronics and soldering, but is not made to natively operate this way.)
