How to choose this product

intrusion-detector

An intruder detector has a sensor which detects anomalous movement or sound indicating unauthorized entry into a building. In such an event, an alarm is activated, alerting the owner, the police or the neighbors.

Applications

An opening detector consists of two juxtaposed magnets, one on the door or window, the other on the frame. When the door or window is opened, the magnetic field is interrupted, activating the alarm.

Movement detectors use radio waves or light beams, including infrared. Any variation in their flow caused by movement activates the alarm. Other detectors are mounted in close proximity to a glass pane, and react to the audio frequency produced by breaking glass.

Technologies

There are several common detector types. Active infrared (infrared barrier) systems use an emitter and a receiver. An intruder moving between the two breaks the contact, sounding an alarm. Passive infrared units detect the heat given off by nearby objects, and activate the alarm in case of temperature variation.

Microwave systems have greater range than the previous types because they can penetrate walls and windows. Electromagnetic detectors sound an alarm when there is a disturbance in the radio waves they emit.

How to choose

Choice of detector will depend on the required level of security, the type of coverage it offers and whether the system is intended for interior or exterior installation.
