Transmission via WLAN and directly to an online storage (thus theft-proof). Unfortunately, these have batteries, I would prefer one with a power connection.
I can only report from our camera (upCam) that if you want a reasonably good image quality, a lot of traffic is generated very quickly and our WLAN bandwidth was severely affected. That’s why we subsequently ran cables.
One must also not forget that depending on how large the monitored area is (e.g., an area with trees, garden gate, etc.), there are many events that the camera interprets as "motion" and starts recording images. For example, the swaying of trees/branches in the wind, the movement of shadows caused by the sun, possibly passing cars, and much more.
For us, that amounts to about 6,000 images per day (!!!) of 150 KB each, so almost 1 GB per day. The recordings go to a server, and the capacity is sufficient. Certainly, one could reduce the sensitivity of the camera. But then you still see a lot of trees and shadows, but not the essential events when someone enters the property.
IMPORTANT: This camera monitors a larger area. If you use a camera at close range, e.g., just directly at the entrance door, then naturally there are far fewer events that trigger a recording.
But depending on the purpose of use, one should consider that regular recording in reasonably good quality means a lot of traffic on the data line. And WLAN performance is poor in this regard (Fritzbox 7490 with repeaters). Our next cam will be a Mobotix then :- )
