IP motion sensors in home automation systems


Using a motion detector as a sensor, a home automation system allows certain events to happen automatically. Motion detectors can automatically trigger a light to come on, a camera to start recording, or an alarm to listen to. Motion detectors can be the eye of your home automation system.
How Motion Detectors Work

Most modern motion detectors are PIR (passive infrared) sensors. This means that the detector does not sense motion but instead changes the level of infrared light (heat) or heat. How to change the light is configurable, this is referred to as the sensitivity of the detector. Motion detectors work best when a warm body touches their front as a person walks. PIR detectors are less sensitive to slow speeds or approaching objects. The general sensing range for a PIR motion detector is 25 to 35 feet (8 to 11 meters) from the sensor.
Shortage of PIR detectors

PIR detectors measure heat and therefore can interpret any sudden change in heat as speed. These may include a sudden sunbeam (opening of the screen), nearby AC and heating units, and a fireplace. If you find that your motion detector is giving a much higher alarm, check its location for possible interference from these sources.
Home Automation Motion Detector

Motion detectors are a ubiquitous component of home automation systems and are available in virtually every home automation technology. Motion detectors are commonly used to turn on lights in a room, adjust the temperature of a thermostat, or alert brake-in protection systems. Many motion detectors are designed for wireless and popular wireless home automation technologies such as INSTEON, Z-Wave and ZigBee. Wireless motion detectors offer the added convenience of being installed in places where electrical power is unavailable. This capability makes these devices essential for many home automation systems. Prices for wireless motion detectors typically range from 25 25 to 40 40.
