We use the Arlo system for peace of mind when we’re traveling. Their smart monitoring works pretty well to cut down on meaningless motion notifications. It will detect general motion, person, vehicle, and animal. You can set up your notifications by each group. You can also set different zones.
Half of mine are battery and half are connected to power. Depending on how much activity a camera gets, the batteries usually last 3-5 weeks.
The only thing that’s a little touchy with them is the night mode, but once you get them setup they work well. The built-in siren is kinda pointless but most alarms are pretty worthless in my opinion.
