alarm wireless
There are different methods of motion detection, i. e. infrared heat vision and microwave. 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. Continue like this until the LED flashes. That’s it.
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. They are usually installed on a wall opposite or adjacent to the protected glass and are effective within about 15′ to 25′. Smoke and Heat Detectors: Detect smoke and heat.
