Installing SimpliSafe® sensors takes less than a minute! In most cases, sensors can be mounted on walls by using the adhesive strips on the back of each device. However, there are some situations where the sensor may not adhere to the wall effectively, like:

• Brick surfaces: the surface can be rough in texture and hard to clean thoroughly 

• Hot and humid conditions: humidity can weaken the adhesive strips

• Cold conditions: a cold wall can cause the adhesive to fail

• Dirty surfaces: the adhesives stick best on clean surfaces

For the best results, we suggest making sure that the area you’re adhering the sensor to has been thoroughly cleaned and dried. We recommend wiping the area down with an alcohol-based cleaning product to make sure it’s clear of any dust or dirt. 

Once the area is thoroughly dry, simply peel the paper backing off the adhesives and press the sensor firmly to the wall for 30 seconds.

If you have a sensor that has fallen off a wall, be sure to test the sensor to confirm that it is still working properly and was not damaged.

Alternatively, SimpliSafe® sensors can also be screw-mounted using the included mounting bracket. See our How do I Install my Sensors by Screw-Mounting article for more information.
