Vibration Door Win

Description:
The Glass Guard Vibration Door Window Alarm is an effective low cost vibration alarm that can be used for securing windows or patio doors. The burglar window alarm can also be used as a personal property alarm to protect computers, TVs, stereo's and cabinets etc.When an intruder is attempting to break-in and the window vibrates more than normal or is broken, the vibration sensor triggers the alarm.These devices are mounted on barriers and are used primarily to detect an attack on the structure itself. The technology relies on an unstable mechanical configuration that forms part of the electrical circuit. When movement or vibration occurs, the unstable portion of the circuit moves and breaks the current flow, which produces an alarm. The technology of the devices varies and can be sensitive to different levels of vibration. The medium transmitting the vibration must be correctly selected for the specific sensor as they are best suited to different types of structures and configurations.
