Installing Motion Sensors – Tips and Tricks for The Best Placement of Motion Sensors

Motion sensors aren’t just used for home security. In industrial fields, they are used on assembly lines to keep track of the number of products and to shut down dangerous equipment if a person gets too close.

Here are a few other ways motion sensors are used:

  • To open and close automatic doors
  • To turn on and off automatic taps and toilets
  • To turn on lights when a person enters a room
  • To control ATM displays
  • At automatic ticket gates
  • For some parking meters

Motion sensors aren’t just an additional feature of a security system—they are essential. Without sensors, there wouldn’t be a way to detect intruders.

If you choose a system that requires professional installation, the installer will know how to set up your sensors. However, you are responsible for setting up your sensors if you go with a DIY home security system. Before you install motion sensors, make sure to read the installation instructions, since they will likely include placement recommendations. Some DIY systems also give you electronic prompts or have you call a representative who will walk you through the setup process.

Keep in mind that motion sensors aren’t error-proof, and there are instances in which there could be false alarms. False alarms are usually caused by electrical failures, user error, poor application engineering, power surges, lightning, and faulty equipment. They can also be triggered by animals, insects, and foliage.

Here are some professional tips and tricks to place your motion sensors in the best possible spots.

The best thing you can do to increase the effectiveness of your sensors and prevent false alarms is to read the instructions that come with your sensors. Also, consider the following motion sensor placement tips:

  1. Keep PIR sensors 3-4 metres away from heating vents, where the sunlight shines in, and radiators. If a motion sensor detects a swift change in heat, even that of a cloud passing quickly over direct sunlight shining into your living room, it could be tripped.
  2. Place motion sensors at “choke-points”—areas where people have to walk through, like the stairwell or main hallway. That way, an intruder will trip the sensor regardless of where they are headed. Intruders usually go right for the master bedroom, so put a sensor near that room or other rooms where you have valuables, like the study.
  3. Walk through your house and assess where intruders are most likely to enter, and what path they would take. Keep in mind that most motion sensors can detect between 15 -25 metres. Most burglars enter the home through a front or back door, patio door, or garage door, so it’s advisable to place the sensors near those areas.
  4. Motion sensors work best when the intruder walks parallel to the sensor, not toward it. For example, in a passage way you tend to walk parallel to the walls, not directly toward them. Find walls that an intruder would walk alongside, like a hallway or narrow pathway that leads to a room.
