First, I’m not looking for anything over a couple hundred dollars. I’m particularly looking for a motion sensor alarm that notifies activation to an I phone. I bought a cheap motion sensor alarm several years ago that I loved at a previous residence. It was loud as hell. Made by a company called Xenon. But, they don’t make them anymore. I’d like a motion sensor or an actual video camera that notifies a cell phone once it’s activated it can access camera via my phone for roughly a couple hundred dollars. Do they make such a thing that doesn’t require Wi -Fi at home ? Any suggestions referring to what I’m looking for would be greatly appreciated.
