The Swann SW351-WSA Window Alarm is a simple, cost effective solution for protecting your home, shop, or office. When mounted on your window and armed, a sensor in this unit will detect any sign of forced entry (vibrations). An ear piercing siren of 110+ dB, loud enough to alert the neighborhood, will sound when the alarm is triggered. The alarm has 3 modes: 'off' when it is disabled, ‘hi’ when it is armed and most sensitive, and ‘lo’ when the alarm will sound only if considerable force is used.

This wireless unit is powered by 4 LR44 alkaline batteries (included) and is meant for indoor use.

      Comments about Swann SW351-WSA Window Alarm:

      not bad, but not as sensative as i expected. it requires a fairly heavy strike or blow for the alarm to sound.
