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. Glass
Break Detectors: Usually mounted near windows to detect the specific high frequency sound of glass being shattered.
We won’t get too much into the deeper technical aspects in this piece. The basic principle is the same for most cameras. The first thing you need to do is position the camera where you intend to keep it. It’s a good idea to start the motion detection at a low setting on your smart phone. All you have to do then is walk in front of the camera and check to see if the device’s LED comes on. If not, increase the motion detection setting and try again.
