home security monitors 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.

Those who take these factors into account, will ensure that everyone is protected and the chances of having any kind of incidents are decreased.
