NFT: Anyone have a Simplisafe home security system ?

buy 3M Lock. That's what its for. Same stuff they use to stick EZ-Pass transponders on your windshield. It works.

but I've put in plenty of motion sensors. They can be configurable from system to system, and some are better at not being triggered by pet movement than others. Worst case scenario, you can always move it away from the couch.

As for the sensors being ripped off - by the time the thief is in, the sensors should have already done their job. The easiest way to defeat a system like this is to kill internet access to the home, since they won't be able to radio out for police. There are ways to protect against that, namely a cellular backup that you'd have to get inside the house to defeat.

Don't put up a sign, better not to alert the criminals to the existence of an alarm system. If you want a deterrent, put up a couple of cameras outside, and if you don't want the expense, put up a couple of dummy cameras outside.

But recently installed a similar DIY system called Abode.

Regarding the adhesive mounted sensors: a burglar removing them is not a concern. They have to be in the house to remove them, which means the alarm should already have been tripped. Even if they somehow got in without tripping the alarm, removing a sensor would break the magnetic field — which would trip the alarm.

A mild concern with these is that adhesive might fail, resulting in a sensor falling and tripping a false alarm. With proper surface preparation it’s not a big problems though. BTW: I decided to forgo the included adhesive in favor of command strips, which are easier to remove without damaging paint when you want to.

As for the motion sensors, flipping them upside down should HELP, but depending on where your dog goes and where the sensors are aimed he could still trip them. Regular mounting aims the sensors out and down; inverting them aims them out and up. So inversion should help in theory, but depends on mounting and how high your dog gets arounnd it’s field.

Of course inverted mounting also makes the sensors less likely to sense a burglar, so that’s the trade off. Another option: the system has a home and away mode. The home mode disables the motion sensors, just leaving the perimeter and any glass break sensors active. You could use that when the dog is home.

Great tip someone once gave me if you feel the need to put up stickers, be smart enough to get stickers for anything other than the alarm you actually have. If you’re dealing with a real thief, tip him off but in the wrong direction.
