I have 2 IPC-HFW5449T-ASE-NI full color cameras installed on construction site. Cameras are used to take snapshots and live view. Snapshots are stored on micro SD. Cameras are powered by 310W solar panels, 90Ah accumulator and Victron Energy charge controller. 4G router is also power by Victron.
Camera has latest FW.
Snapshot type - general, interval is 180s, snapshot storage schedule - 00:00:00-23:59:59 - General. Motion detection and smart plan are off.
Trouble is that snapshots are taken approx. till 21:30 only. Camera continues taking snapshots only after reboot. This problem was with one camera. Second one was working normally until couple of days ago I've set up profile management schedule - day 07:-20:00, night 22:00-24:00 ; 00:00-07:00 and changed exposure for night time. Now both cameras takes snapshots only till ~20:00

What have I done wrong? What might be the problem?
