I am a licensed security integrator and I put one of these systems in my mother's house. They are great and easy to install, customer support is great and the equipment is great. Monitoring is very reasonable and equipment costa are great. Highly recommend.
I have 6 of them
One for my office
One for my residence
4 that I Keep floating around for my different construction projects(I am a general contractor)
As soon as I get a project lockable it gets alarmed
Has cut way down on theft
Anything wireless can be easily hacked. Hard wire is the way to go. Wi-fi is simple to install. Wi-fi goes down too often. Watch a couple of YouTube videos on the Simpli -Safe set up before you buy. Of course this is just my opinion. I wired my house when it was built 30 years ago. Never a problem.
One of my sub contractors uses these. He claims they are so encrypted that they can't be hacked. He showed me real time video and some recorded video. Super clear.
