For this reason ALWAYS put the sign of a different alarm company in your front yard- especially if you have SimpliSafe. Example- if you have ADT in your house but a BRINKS sign in your yard. You can get signs and window stickers from any company on eBay or Amazon

I watched a YouTube video also, but the $10 device didn't work. A more expensive one did work. The reason it works is because the SimpliSafe system uses a fixed frequency for communication between the base unit and the detection devices. The defeating device creates interference within the security system by using the same frequency. I don't put any security company signs outside of my house. I think the SimpliSafe system is good enough to deter most burglers and way better than having nothing. It's very easy to install and operate.
