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

Simple safe is the best. Great optiond and devices.

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.

Seamless integration to the existing SimpliSafe security's system.

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.
