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

I updated to the SS3 in 2018 and have been using these sensors every since. I easily get 5 - 7 years out of these sensors. They are very easy to set up and pair with your base station. Depending on your security settings, the sensors will notify the base station when a door is open (with the alarm off) and a tone will let you know if door has been opened and of course if the alarm is set, you will get an audible alarm from your security system.If by chance, you do have an issue with the sensor, just call SimpliSafe and they will replace it.Highly Recommend

I'm very satisfied with the product you sent. It's installed and works perfectly!

Hopefully these will work longer than the previous ones. It seems as if they are all set to stop working around the same time. They work until they don't work anymore. Pretty simple set-up. Appear to be durable.

Why did you pick this product vs others?:We have simplisafe system and required additional sensors for windows.

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.

Quick shipment and product set up easy, added additional windows to my system and quite happy!!

Work perfectly.

Great product
