Motion Sensor - Compatible with Gen 2 Home Security System

Don’t buy this product if you live in Canada, their product doesn’t work in Canada

I bought this to replace a 6-7 year old motion sensor. The batteries last a little over a year, but this time, a new battery just wouldn't work, so I bought another. They are cheap enough not to worry about, and the one I had was WAY out of warranty. I only use the motion sensors when we are away. for us, in a small house, the motion sensors are a bit of a PITA when we are home, so I set them up to only turn on when when we are away. I also installed this one upside down, these devices can sense movement forward, and in a 90 degree angle to the left, the right, and downward. Even though I have the pet filter tuned on, my cat would still trigger it. So I installed it upside down, so that it would sense forward, left, right and upward. I then placed it at roughly human head height. That way, only humans will trigger the device. (Well, elephants too, but they hardly ever do a B&E according to police) BTW, this is a common setup procedure for heat sensitive sensors with highly directional sensitivity.

We are very happy with the SimpliSafe system. Originally we got one for someone else and then bought our own. We have had permanently wired alarm systems at 3 prior homes and this does everything those systems did. Installation is easy, the tech support people helpful and the alarm center monitoring very good. The motion sensors are very sensitive and the cameras perform well.

Works just fine, exact Simplisafe product

These are a great addition to the SimplySafe security system. They're easy to install on any flat or corner walls, have not had a false alarm since installing a week ago, and doesn't detect my two cats. They're not a distraction to a space, not intrusively big and not really noticeable, yet they're big enough to make you notice that the house is secure if you're an intruder looking for security system device sensors. I highly recommend adding these to your SimplySafe security system.
