SimpliSafeEntry Sensor (Pack of 4) - Window and Door Protection - Compatible with The SimpliSafe Home Security System - Latest Gen

Works as desired.

Easy to set up

Apparently they wear out after 7 years or so but I bought these placed them and Shazam they worked perfect. I always change the batteries once a year but this time it didn’t work for a few.

Easy to use OEM replacement sensors

Never had something like this before and gotta admit I like it. So nice to get the alert when a door opens, I got puppies so I worry about that. Sometimes I wont close it tight enough and the wind will open it etc, so its really nice for things like that. Also, when family is coming over I just leave the doors unlocked so its a nice quick way to get notified they arrived when they come in.From the security perspective that peace of mind is just pretty nice to have...whether its worry a small child might get out or a stranger getting in. I bought the bracket to mount it on the garage door and that works great too.

They work

These SimpliSafe entry sensors are incredibly easy to add to an existing or new system. Setup takes just minutes, and they work flawlessly. I’ve purchased these multiple times and now have all my windows and doors covered for complete home security. Reliable, effective, and a must-have for any SimpliSafe setup. Highly recommended!

I have used a complete SimpliSafe Alarm system (base, entry sensors, doorbells, locks, cameras (both inside and out), smoke and CO2 detectors) in my home for the last 3 years after building a new home. I previously used a major alarm company in my old home. Set up with the SimpliSafe alarm system is so simple anyone can easily do it. I have these entry sensors on all my exterior doors and windows and have begun to put them on key interior doors. The reason for placing them on key interior doors to detect movement within the home during an alarm. I also placed them on doors to key storage areas for the same reason with these set to instantly trigger the alarm. I bought the 4 pack because it was less expensive then purchasing them individually. I have already used two of these and have the other two for future expansion of my system or in case a sensor fails (which I have yet to have happen).
