Adding Motion Sensors to Your Home Security

October 1st, 2019

Motion sensors are a basic part of any home security tool box. Most packages come with a motion sensor or image sensor that can trigger alarms, alerts or automate smart home functions. Learn a little more about different motion sensor options and how they work in this article.

How Motion Sensors Work

Motion sensors work by sending out signals; these signals could be passive infrared, microwave pulses, ultrasonic, LED, or vibration. When the signals are disrupted or tripped the motion sensor triggers an alarm, alert or a programmed automation. Some devices use dual technology, meaning two different sensors would need to be tripped in order to trigger an alarm, reducing false alarms.

These alerts are a great way to stay informed about activity in your home. Photo alerts from an image sensor provide more peace of mind because the motion alert is accompanied by a photo of the area allowing you or your security monitoring company to identify if a triggered alarm is real or false.

Pet Immune Motion Sensors

We love our animals and know you do too, but they do pose certain issues when it comes to motion sensors. Luckily there are pet immune sensors on the market that will not activate an alarm or alert for your animal. These sensors are often rated by weight, for example immune to animals under 30 pounds or immune to animals under 60 pounds.

When looking to add motion sensors to you home security system, inform the security company of your pets and they can recommend the right solution for you.

Video Motion Detection

Many indoor and outdoor security cameras also have video motion detection available. This allows you to use video as part of your security system but doesn’t require cameras to record 24/7 and bog down servers or cloud storage with hours of footage. Motion triggers the security camera to record a clip. Depending on the camera you can usually set the duration of the recorded clip, how long it should delay before recording more clips and if anyone is alerted of the motion.

Since you don’t really need or want cameras recording your personal activity within the privacy of your own home you can also use Bluetooth geofencing capabilities to turn video recording off when your smartphone is within the geofence.

Where to Position Motion Sensors

First and foremost, you want your motion sensor in an area that will detect an intruder. So, it should be placed near an entrance door or near a room that holds valuables like a study or master bedroom. Be sure to place the motion sensor in an area that you know an intruder would have to cross or in “choke-points” like hallways or stairwells.

You can also use motion sensors for turning on lights or sounding doorbells, in these instances it would not trigger an alarm, but a different type of smart home function.

A security professional will be able to give you advice on where your motion sensors should be placed. They will also know the guidelines from the manufacturer that will reduce the chance of false alarms being triggered.
