A lot depends on whether you need real security with a service to call the police, fire, etc, or you just need video surveillance/person detection and maybe door/window/motion sensor alerts so you can review and then call authorities as desired. In any case I’d never suggest ADT. When renting in FL the owners had ADT and it was a constant price increase even with a contract in effect, they always retain the right to raise the cost. I those 6 yrs, even in So FL, we never had an incident nor had any neighbor - but then those we guard gated communities. After we bought a house, I put in a wifi cam to watch front entry and one for watching back patio. Never had any incidents. I can’t recommend the company though - decent cams but they constantly push out app and firmware updates and not always reliable - kind of like the software side is in a constant beta state. Plus they’ve outgrown their ability to support users responsibly. I don’t know about reolink or amcrest for customer support but have hear the hardware is decent. Eufy is popular since they have a lot of options that do not require subscriptions/ a tad pricy and I don’t know much about their support either.
