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!

This was a great value for the product. All SimpliSafe items seem to be reasonably priced except for the video doorbell that doesn’t work. These stick well, connect so easily, and are triggered according to their settings in the app. I will be purchasing one more pack of these to complete the set up.

SimpliSafe is an easy to use, easy to install system. We set of the smoke alarms twice from high heat cooking in cast iron skillets. Both times - before we could turn off the alarm - SimpliSafe called to check in. They already had the fire department alerted, but not rolling.Fantastic service. The doorbell camera is great - I never have to wonder who is at the door - I can see on my phone. I also appreciate the panic button, which I think of as an emergency back up.Worth watching for a sale and getting the full setup.

These door sensors were very easy to install and have worked well with my SimpliSafe system. I don’t have any connectivity issues and the batteries have lasted a few months now. Additionally, the sensor is loud enough to hear through the house, but not so loud it will wake anyone up.However, I really wish they had a black version. I have some black doors, so I had to paint over them, which doesn’t make them look as professional. This is also a hassle to do for every black door you have, as you have to tape the sensors off, wait for them to dry, and hope you didn’t mess up or smudge some of the paint. For this reason, I am giving them a 4-star. This goes for all SimpliSafe security products—please add a black version of every security product!Other than that, I recommend these to anyone who needs a solid door sensor.

These sensors work great and are easy to install and add to your SimpliSafe home. I really enjoy that the sensor does not have to be perfectly aligned to function properly which makes them more versatile in my opinion.

The SimpliSafe entry sensors have been a game-changer for my home security setup. These compact devices are incredibly easy to install - simply peel off the backing and stick them to your doors or windows. The wireless design means no messy cables, and they sync seamlessly with the SimpliSafe base station. What's most impressive is their reliability; I've had them for over a year, and they've never failed to alert me when a door or window is opened. The battery life is also impressive, lasting much longer than I expected. SimpliSafe's mobile app allows me to monitor their status remotely, adding an extra layer of convenience and peace of mind. These entry sensors are a cost-effective and essential part of any home security system

I have had my SimpliSafe system for about a month. I found it VERY EASY to install and connect to the base. It basically does it by itself when you turn it on and name each sensor whether it be the motion detector, the glass breakage sensor, entryway sensors that you put on the doors and windows, the cameras or even the extra 105dB Sirens that are also wireless. It is all extremely easy to install and connect to the SimpliSafe Monitoring. I have shopped for security systems for a couple years now and decided on this one because they had a special deal where I could get a free camera. I was really happy when I found out how well the system works and the fact that if the Wi-Fi goes down it will go straight to cell phone ability and contact SimpliSafe Monitoring if needed in an emergency. I also like the fact there are sensors you can buy later like a water leak sensor, CO2 sensor, temperature sensor so your water lines won't freeze which would be good for vacation cabins and such. They are all very easy to add later when you want to. TODAY I found out I get a discount on my homeowners for having a monitored alarm system. I am so impressed with the SimpliSafe system. YES I would definitely purchase the entire system again and probably will soon for a second property I own. Without a doubt this is an impressive system.
