Infrared Protection for Any Room of the House

The backbone of a security system, a home motion sensor alerts you to the presence of an intruder without alerting them. Instead, you’ll get an instant smartphone alert and a call from a Vivint professional, so you can take action.

The Vivint Motion Sensor forms an active “grid” of 30’ x 50’ and uses passive infrared (PIR) technology to detect heat signatures and movement within that range. Pair that with its impressive 110-degree wide-angle viewing radius and 90-degree lookdown, and you’ll find this wireless motion detector can detect almost anything that crosses its path.

Plus, its slim and sleek design means you can discreetly place it anywhere—from your front porch to your backyard patio.

Smart Features for a Smart Home

The Vivint Motion Sensor comes packed with perks as the foundation of your home security system.

Frequently Asked Questions

How do I change the battery in my Vivint motion detector?

It’s simple! First, disarm your system, unscrew your motion detector, and dismount it. From there, you can pop out your used CR123A batteries and place in new ones. Since these lithium batteries are a similar cylindrical shape to an average household battery, there aren’t any special techniques needed. Plus, they last for 3–5 years, so you won’t need to do this often.

Can a motion sensor be triggered by light?

Since the Vivint Motion Sensor detects heat, light can trigger the motion detector alarm if that light is hot enough.

What do motion detectors do?

Vivint motion detectors use passive infrared (PIR) technology to detect heat and movement within a 30’ x 50’ range. These wireless motion sensor alarms then alert you via the Vivint Smart Home® App, where you can connect to a Vivint monitoring agent 24/7.

How do motion sensors work in the dark?

Motion detectors work in the dark by sensing heat and movement, so your Vivint Motion Sensor alarm works just as effectively day or night.

How far can a motion sensor detect?

The Vivint motion detector sensor can detect heat and movement within a 110-degree angle and a range of 30’ x 50’.
