Where Should I Install My Motion Detector?
You should install your motion detector in a location where it can adequately detect motion, but also without causing any false alarms. The best location for a motion is usually in the corner of the room, away from any windows. The device should be placed about 6 to 8 feet off the ground.
There are several rules to remember when deciding on a location for a motion sensor. First, it should be placed away from any heat sources, such as vents or ducts. That is because the change in temperature could cause a passive infrared (PIR) motion sensor to activate. This is also why motions should be placed away from windows. The incoming sunlight could potentially cause the motion to activate and cause a false alarm on the security system.
Instead, a good location for a motion is typically in the corner of the room. This will provide it with the widest detection coverage of the area. Hallways often make a good location for motion sensors, since an intruder will need to pass through these areas to get to any particular room inside the building. Some users also choose to mount motion detectors on the ceiling, directly above a door or entryway. This way, as soon as a person enters or exits the room, the motion sensor will activate.
The ideal height for a motion sensor is typically 6 to 8 feet off the ground. At this height, the motion detector will be able to detect any person who is walking upright in the area. This will also prevent the motion from being set off by any pets who are walking lower to the ground. Remember, different motion sensors have different ranges and scopes of detection. Most motion sensors can also be adjusted by swapping out the detection lens or covering up a portion of the lens. Always make sure to test a motion to make sure that it is properly picking up movement in the area.
