It is obvious what most sensors do, so we will only describe the main ones used in a basic system. Contact Sensors: Most burglaries involve doors, either on entry or while leaving the house. So protecting all doors is a must. Example: magnetic circuit breakers. Door contacts may be hardwired or wireless; hardwired contacts are usually buried in the doorframe, which is less obvious than wireless and are preferable. Window Contacts: Can be hardwired or wireless. Motion Sensors: It’s the most essential and common form of protection. Passive infrared sensors: Detect motion by sensing a sudden change in heat. Dual Tech motion detectors use two different technologies in the same unit: passive infrared and microwave. These devices are designed to avoid false alarms since both technologies must detect motion before setting off the alarm. Photoelectric Sensors: These sensors project a beam of light across a hall or doorway to detect motion and are triggered when a person passing through interrupts the beam.
