Arrived with cheap panel tablet that you plug in. Back wasn’t secure and kept saying tampered with. Their fix didn’t work. Half the *** promoted on the video didn’t work when I tried to set it up and pieces were missing. Batteries were dead and the smoke detectors didn’t work. Sent those back. Also claimed some sensors from prior system would work. Found out tech needed codes to synchronize then. Took several calls and still not working but grace period over so stuck with this *** Will have to get attorney to get out of this bit then I’d have spent way more money.
