PIR, or passive infrared motion detectors, are not only the most commonly used types of sensors to detect motion, they can determine the temperature of objects in a room.An slight movement or change in temperature in an area of the room triggers the alarm. For this reason, PIR sensors are the most important part of home security system, which adds an extra layer in home security.However, Placement of motion sensors is very important in order to maintain your highest level of protection.
Do’s
•False triggers can happen when a motion detector is not correctly mounted. If the sensor itself moves, it could register that as motion and trigger your alarm.So Mount Sensors such that it does not move.
•Placement of motion sensor in a corner of the room with a view of each entry point is one of the most effective placements.
•When an Burglar breaks into a house the first thing they’ll look for is the motion detector and alarm system. They’ll likely assume it’s placed along the wall, so trip them up by placing it on the ceiling. Many sensors on the market today work at any angle, so place sensors on the ceiling near the front and back door.
Don’t’s
•Placing Motion Sensors directly across a window must be avoided in order in reduce false triggers ,Because the heat-activated motion sensors can be confused when placed directly across from sunlight, particularly on a hot day or when a cloud passes by blocking the light.
•Don’t point places where your Pets can climb.
•Don’t Place PIR motion sensors near any heat sources like air vent or radiators. The change in temperature may lead to false triggers.
