I've had Vivint since 2021 and their salesman was good. He stated they're US based and manufacture all their equipment in-house. He also said I could go to him for anything even after the installation. A month after the installation was done and they got my money, he'd refer me to call support. Fine. Typical salesman. Onto their equipment: I've had to replace the Smart Drive, a doorbell, and multiple Wi-Fi Bridges (the part that plugs into the wall). These items aren't cheap. For 2 cameras and 2 doorbells, it cost $3800 and that doesn't include tech visits (which they will do only after lengthy troubleshooting calls for $99). One camera goes offline everytime we go on a trip (which is the worst time to go offline since you'd like to monitor AND you must be present for troubleshooting). Other cameras and doorbells go offline multiple times during the day. Vivint has introduced their updated line of overpriced stuff and a newer camera with better features will run $600. For one camera. May want to steer clear of Vivint unless you like overpaying for cheap crap with poor customer service.
