Depending on how and where they are set up, motion sensors can detect motion inside or outside your home or business and turn on lights, sound an alarm, or even trigger a doorbell if someone comes near the front door. They can sense a door or window opening or a breaking window, whether the intruder is a burglar, a teen breaking curfew, or an errant spouse sneaking in late after a night out. If you don’t want kids, guests, or employees to enter specific rooms or areas of the building, a motion sensor can alert you when someone tries to enter. Many sensors use passive infrared (PIR) technology to reduce false alarms.
As components of an automation system, motion sensors are for a lot more than security. They turn off unused lights or sense when to turn them on, open gates, or turn automatic faucets on or off. This feature is particularly useful in public buildings where traffic is variable and improves convenience and security for users while saving energy to the building owners.
Picking the best unit can be a challenge, seeing the many devices in the market. However, our buying guide suggests what to look for and recommends the best motion sensors.

Best Motion Detectors Selection Criteria
The best motion system to meet your objectives depends is one with the features that will facilitate your security, convenience, or other goals.
There are three major types of motion sensors on the market, and each has its pros and cons.
Passive infrared – This type of sensor, known as PIR, creates a protective grid to detect heat and motion but eliminates false alarms caused by blowing foliage or other inanimate objects. If an object blocks too many grid zones or causes a rapid change in the energy level, the sensor triggers an alarm. These are the most common motion sensors in the market.
Active sensors – Active sensors use infrared energy, radar waves, or other methods to detect changes in the rooms they cover. By emitting ultrasonic, microwave, or radio pulses to pick out the reflection from moving objects, this type of sensor sounds an alarm based on how long it takes for pulses of energy to bounce back to the source. These sensors are quite pricey and likely to cause false alarms by inanimate objects such as foliage.
Dual Technology – These combine features from two types of motion sensors and are ideal for curbing false alarms and protecting rooms with high ceilings or tall furniture. A dual tech sensor could be passive infrared and active ultrasonic, microwave, or radio tech. In this case, no alarm will go off unless both types of sensors are activated.
Indoor or Outdoor
Sensors placed indoor and outdoor sensors have their place in a security or automation system.
Other than offering security, indoor motion sensors lower utility bills and increase convenience. Whether you are coming home at night and your hands are full, or your kids hit the bathroom in the middle of the night and need illumination, automatic lighting goes a long way to ensure you don’t fumble and stumble. As lights are only activated when needed, you can save energy.
Nevertheless, they do have their shortcomings as you could be doing something late at night and don’t want to bother your partner, but the lights will come on anyway. Investing in a timer can mitigate these risks.
Outdoor sensors are often used in tandem with security cameras. However, pets and pests can trigger them, so you should consider a dual technology system to prevent false alarms.
Reset Time is how long the unit takes to shut down whatever it activated (say lights or an alarm). For example, a motion sensor with a one-minute reset time will take one minute from when it starts to when it deactivates, provided no motion is detected.
A unit with long battery life shouldn’t fail to work at a crucial moment. Moreover, you will spend less on batteries, and you will change them less frequently.
If there are pets in the home, pet-immune motion sensors can prevent false alarms as they stroll by and activate lights or sound. Depending on your pet’s weight, sensors can ignore motion. However, alarms can go off if the pet jumps on a table or if there is a sensor near a stairwell, as the size of the pet appears to increase the nearer it comes to the sensor. Owners with very large pets might need to use glass break detectors that detect if the glass is shattered or broken rather than motion detectors.
Compatibility is an essential feature, seeing as the home automation and security industry is massive. We recommend you get a unit that supports most home automation infrastructure.
1. What are driveway motion sensors?
Driveway motion sensors are outdoor detectors commonly used on driveways. They differ from other units in that they include a receiver and have a range of up to 400 feet. They can also be used to monitor sheds, stables, pools, or any other large structure. However, for warehouses, private hiking trails, or extensive areas, you need a device with a range beyond a ½ mile.
2. What are some of the causes of false detections?
Pets and particularly large canines are the most common causes of false alarms. However, some motion sensors can be triggered by sudden sounds, bursts of air, and white light. A pet-immune system can prevent most false detections – though you may be out of luck if you have a great dane.
False alarms also occur when there can be sudden movements from blinds or other objects in the room. You can also adjust the sensitivity of your system to ignore such motions.
3. Are motion detector guard dogs a thing?
Well, this may sound silly, but yes, it is. Motion detector guard dogs are for people who desire a guard dog but don’t want to deal with an actual pet. The gadget produces barking sounds should it detect a person approaching. Furthermore, as motion detectors are easy to hide, this type of detector can be hidden in a hard-to-see area. Finally, you can adjust the volume and speed of the barking depending on how far or close an intruder is.
Motion detectors are a vital part of any home system. Though they are often used for intruder detection, they are versatile and help with home automation. You can rely on the devices to light up rooms you walk into or start and stop home systems such as fans and furnaces as long as you get a gadget that meets your expectations and is within your budget.
