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

One real weakness of the system is the limited range of the wireless sensors. If they are around too many corners or downstairs, they tend to go offline frequently. Simplisafe’s claim of a 600 foot range is bogus, and their customer service reaction to every problem is to send you a replacement. They even replaced a perfectly good base station because they couldn’t upload new firmware and thought that was the problem. I’ve worked every angle, and the problem is indeed poor range of the sensors. Never had this problem with my “old school” proprietary alarm system from All Guard.

These entry sensors are a good size and were easy to add to my SimpliSafe system. They have good range (wireless) and the batteries they came with were fresh. I was a little disappointed that the individual packaged units didnt have an extra/second 2-sided 3M mounting tape in case the unit had to be adjusted/relocated during installation. That would be a nice added feature. (The whole package system Owners Manual also stated that there were extra 2-sided mounting tapes included, which wasnt correct.) Not enough of a negative to change my overall rating, but a bother that could be improved upon.

1/3 of my sensors had a sticking issue where I had to use duct tape to get it to ACTUALLY stick. Other 2 were fine, so far. System is actually good, wife loves it.

I needed to replace a few sensors for my doors. I love the easy to use system

Great addition to my set up.

The main thing I like is that these sensors work. I am personally having a hard time knowing how to attach them and if I am doing it correctly. Are there people in my area who can do this for a reasonable fee?

I purchased 3 boxes of four sensors to put on my windows. Positive - the sensors came early and work well. Negative - some came with dead batteries. Must’ve sat on a shelf for a few years before they were sent to me.

The concept for the sensors is fantastic, but hey just fall off the door frames and or walls. I cleaned the areas with alcohol and allowed to dry before applying the sensors and they would just not stick or fall off a day later. They would have a great alarm system if this could be overcome. I would hate to leave my home with the alarm set and have a senor fall off and then trigger the alarm. If it was monitored it could become very costly in false alarm fines.

Bought extra SimpliSafe Entry contacts. SimpliSafe is a great alarm company.

Fell off door a couple of times. Have to pay to monitor remotly
