How To Place Motion Sensors In Your Home?


Motion sensors are the first line of defense in home security. Motion sensors detect any movement within your home’s area that the product monitors or known as the field of vision. Within the area they cover, they can pick up on suspicious and sudden movements.

The motion sensors will spring into action if any motion occurs within the area your home sensors are continually scanning. Motion sensors can sense if someone is entering or an area of your home and respond to that invasion. By placing a motion sensor near a door or hallway, you’ll know if someone is in your house, driveway, or yard when they shouldn’t be.

Motion sensors in the home act as an extra set of eyes watching the places you can’t see or whenever you’re not home, so it’s essential to make sure each sensor has a clear line of sight.

Motion sensors are in many forms like cameras, alarms, lights, and each of these has their particular features to help guard your home. They are the perfect security devices that give users the ultimate control over their property.

First of all, check out the ideal placements for the motion detector –

Placement plays a large part in installing the motion sensors in your home. They function by detecting a fluctuation in heat, so a sunny window or near a heating element won’t make sense for their placement. check out places –

  • High Traffic Areas

    Those areas of your home where the floors get worn down the most through the years by people walking all the time are great locations for installing motion sensors because an intruder will have to walk through those spots.

  • Corners

    The broadest view of a room will give your sensor a good look at the indoor as well. Motion sensors can be best placed in the corner of the room with a good view so that motion sensors can easily detect any movements.

  • Over a doorway

    You can place the motion sensors out of intruders’ sight by setting them just over an exterior door. They won’t know it’s there until it’s already alarmed.

  • Basements

    Having several motion sensors down in the basement area is a great idea. Make sure you install them in an area where they won’t be blocked by the clutters. Also, consider installing one near the stairs leading upstairs.

Ignore places likes –

  • Near a Heat Source

    It is good to keep motion sensors away from hot air vents, windows because of sun and radiators because a heat source could create a false alarm. If the motion sensor detects any change in infrared heat, it could trigger the alarm.

  • Stairs

    If you have pets, it would not be right to install motion sensors on the stairs. Because then you don’t want your motion sensors to get triggered by your pets, also, avoid putting sensors at the top of stairs. As your pet climbs the stairs, it will look more significant to the motion detector, and it could set off an alarm.

  • Behind Large Furniture

    If you place motion sensors above a piece of tall furniture that sticks out far from the wall, the furniture could create a blind spot or a shadow—infrared motion detection beam like a flashlight beam. Avoid installing motion sensors on a wall near the top of a large entertainment center, wardrobe, or other large furniture pieces. Avoid putting it over a large part of the furniture, like a bookshelf or entertainment center, limiting the passive infrared energy range.

Few unique features to keep in mind before buying motion detectors –

  • Wireless:

    Always choose a wireless device; it will make your life easier. No wires mean no drilling and more straightforward installation. The wireless motion sensor will interact with your home security system wirelessly, and these are the most common type of sensors used today in most homes.

  • Sensors immune to pets:

    Pet owners are never sure what their pets are up to while they’re away. Your motion sensor would detect the unnecessary movements of the pets and get alarmed. Some passive sensors can be mount to ignore your pet’s actions. You can usually set them up to neglect pets up to a certain weight. In this way, they should still be useful for protecting your home from unwanted human intruders.

  • Sensors with video capability:

    Some motion sensors work along with video security systems. So, by using this, the camera will only record when the sensor alarm. This technology saves on memory for your security camera. Also, it comes in handy to have video evidence of a break-in.

  • Contact sensitive:

    These contact-sensitive types of sensors installed on doors and windows are typically passive infrared sensors. They would alarm your security alarm instantly if a door or window opened in your home.

Steps to place motion sensors in your home –

  • Step 1: Open the kit

    The motion sensor kit comes with some instructions and mounting hardware. Put batteries in your motion sensor if your device has separate cells.

  • Step 2: Choose a location

    It would help if you considered the most effective sensor placement before mounting your motion sensor. As you have read before, corners are ideal because you can place infrared sensors to cover the most area of the room. They have designed with angled edges with screw holes, so they fit nicely into the corner of a room.

    Mount your motion sensor high on the wall to get the best view. Make sure your motion sensor is installed opposite the room or hallway’s main entrances to pick up on any intruders right away.

  • Step 3: Install the sensor

    While installing passive infrared sensors, you won’t have to worry about drywall anchors or studs because they are lightweight. You can use an electric screwdriver for installation; it can make the process go faster.

    Most motion sensors have an installing bracket that pops off the main body of the device so you can screw it into the wall first and then clip the motion sensor back in. This bracket also makes it easy to take the motion sensor off the wall for any other issue or maintenance. Sometimes, other infrared sensors may require a full disassembly for installation.

  • Step 4: Connect the sensor to your system

    For connecting the sensor to the system, you can follow the manufacturer’s instruction manual to connect your system’s motion sensor. You can connect motion sensors to lights and other smart devices through the hub to turn on whenever the sensor detects motion.

  • Step 5: Set your motion sensors’ settings.
    Most motion sensors have three main settings when your system is armed: instant mode, entry delay mode, or interior follow-up mode.

    Instant mode- any motion the sensor detects will trigger an alarm.

    Entry delay mode- the sensor will operate on a delay, it will give you 30–60 seconds to disarm the system before sounding an alarm, even if it detects motion.

    Interior follow-up mode- If a door contact is triggered first, it works like the entry delay. If this mode detects motion in the home without a door contact first triggered, it will sound an instant alarm.

  • Last- Maintain your motion sensor regularly

    Dust and debris can accumulate on the screen of the motion sensor and interfere with the infrared energy over time, making it less effective at detecting movements. Clean and maintain it at least once every couple of months. You can use a dry or slightly damp microfiber cloth. Remove the motion sensor first, if you decide to paint a wall near the device. If you drop any paint on a passive infrared motion sensor, replace it immediately.

Conclusion –

There are various types of motion sensor technologies to choose the perfect one. Know your space and environment is essential to choosing the right motion sensor for your home. It matters when you’re planning where to install them throughout your living area. Motion sensors are a vital part of your home security system and can even save energy costs.

Motion sensors are essential; they aren’t just an additional feature of a security system. Motion sensors play a vital role, and there wouldn’t be a way to detect intruders without them.

Hopefully, this motion sensor guide taught you how to place the motion sensors in your home to do their job correctly, the motion sensor’s role in your home’s security, and the various technologies employed in motion sensors.
