In effort to build on an existing thread and simplify future searches, is there now a system that has become the clear choice in the two years since this thread was started? My criteria is Reliability. Simplicity. Cordless cameras not subjectable to hacking, High image resolution. Outside weather proof. Recall images days later. Cell phone alerts for after hours activity. No on-going fees. At this moment, who's product is a best choice?
I have been through this a few times - think you also need to have a view of how you want the camera to function
1 - constant recording (like most shops have), this really rules out battery
2 - one you are/disarm manually (eg like you house alarm, active when you are out)
3 - automatically arming (motion or geofencing), can be a pain in high traffic areas
4 - other
For me, the Geofencing was critical (my cars are in a separate shed, wanted the alarm to automatically disarm when my mobile was close, auto arm when I am away). Not many do this, I have an old system (Kidde RemoteLync) of 4 cameras that works really well but not 2K video and the batteries last around a month), recently upgraded to a new Arlo system (good quality but OS is a little flaky and you need to subscribe to keep videos)
For your situation - maybe the EufyCam2 comes with a 365 day battery, indoor only but seems to be getting some good reviews
Its a moving target though, new stuff coming out all the time
cheers
