I have just bought numerous Tapo C425 Cameras (mixed with some solar panels).

Sadly, it looks like i have made this decision off the back of old information and functionality supposedly available in previous firmware versions.
I.E. i was under the impression i could use ONVIF to store video streams on a local NVR.

Some details about my situation:

1. Ultimately I don't care so much if i can see live streams via a local NVR.
2. However, I do care about being able to pull down the recordings to archive on a NAS or similar periodically. Eg. every X configured hours.
3. My internet availability is considered sketchy at best. I don't want to use cloud services.
4. The cameras would be mounted where they are difficult/painful to access. I don't want to have to get up on a ladder every now and then to copy the content onto local backup.

How do I remotely connect to the camera from the local network and gain read-only access to the recordings (xxxxxxxx_xxxxxx_tp00000x.mp4)?

Thanks.
