How Do Motion Sensors Work?

A motion sensor (or motion detector) is the linchpin of your security system, because it’s the main device that detects when someone is in your home when they shouldn’t be. A motion sensor uses one or multiple technologies to detect movement in an area. If a sensor is tripped, the light floods the surrounding area and illuminates anything in its path.

Types of Motion Sensors

The following types of motions sensors are used in lights to detect movement.

Passive Infrared (PIR)

Detects body heat (infrared energy). Passive infrared sensors are the most widely used motion in home security systems. When your system is armed, your motion sensors are activated. Once the sensor warms up, it can detect heat and movement in the surrounding areas, creating a protective “grid.” If a moving object blocks too many grid zones and the infrared energy levels change rapidly, the sensors are tripped.

Microwave (MW)

Sends out microwave pulses and measures the reflection off a moving object. They cover a larger area than infrared sensors, but they are vulnerable to electrical interference and are more expensive.

Dual Technology Motion Sensors

Motion sensors can have combined features in an attempt to reduce false alarms. For example, a passive infrared (PIR) sensor could be combined with a microwave sensor. Since each operates in different areas of the spectrum, and one is passive and one is active, Dual Technology motion sensors are not as likely as other types to cause false alarms, because in order for the alarm to be triggered, both sensors have to be tripped. However, this does not mean that they never cause false alarms.

Area Reflective Type

Emits infrared rays from an LED. Using the reflection of those rays, the sensor measures the distance to the person or object and detects if the object is within the designated area.


Sends out pulses of ultrasonic waves and measures the reflection off a moving object.


Detects vibration. A vibration sensor uses a small mass on a lever, which is activated by a switch to an alarm when it vibrates.

1byone Safety Driveway Patrol

1byone’s Safety Driveway Patrol is a durable outdoor alarm system with one or more weatherproof motion sensor panels (you choose). The Driveway Patrol unit has three chime options, and the speaker is about the same size as a baby monitor, meaning it can be covertly positioned without looking out of place. Since this system comes with multiple sensors—it can easily network with up to six sensors—the alarm is able to cover multiple areas at once. The biggest problem with this alarm is that movements in nature easily trigger it — the sensitive detectors pick up on nearly any movement, including that of birds, insects, and even tree branches moving in the wind. Secondly, the Driveway Patrol does not have any outdoor light or sound features included. So while the sensor will alert you to incoming visitors, it may not deter possible intruders.

RAB Super Stealth

The RAB Super Stealth is one of the sturdiest motion-activated floodlights available. This industrial-grade motion lighting system offers a 60-foot detection area, and the motion detector senses 180 degrees out and 360 degrees down. Secondary sensors monitor behind and below the light. It’s also protected from power surges and radio frequency interference. The RAB Super Stealth is a big light, so it’s not a great choice for those wanting small or discrete sensors. The cost is also relatively high, with a single unit running about $90. You’ll need to be handy with a drill to get this light installed, because the RAB must be wired into a hardline and its mount must be securely fastened into a sturdy surface.

This motion sensing light can handle bulbs up to 1,000 watts.

Motion Sensor Light Placement

Before you install motion sensor lights, make sure to read the installation instructions, since they will likely include placement recommendations.

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.

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

  • Keep PIR sensors 10—15 feet 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.
  • Place motion sensors at “choke-points”—areas where people have to walk through. That way, an intruder will trip the sensor regardless of where they are headed.
  • Walk through your yard 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 50 and 80 feet. 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.
  • Motion sensors work best when the intruder walks parallel to the sensor, not toward it. For example, in a yard you tend to walk parallel to the hedges, not directly toward them. Find areas that an intruder would walk alongside like exterior walls along paths.

Installing motion activated lights is an easy weekend project that can help discourage intruders and make the area surrounding your home safer. Ultimately, the motion sensor light you choose will come down to your needs. Take some time to figure out exactly what you want from a motion sensor light, and then give one of these products a try. To help make your home even more secure, consider getting a home security system with security cameras, alarms, 24/7 monitoring, and other great features.
