On all cameras?
What models of camera, and how are they connected?
Do the cameras have a scheduled day/night profile configured?

Yes all camera

camera models are IPC-HDBW1230E; IPC-HFW1431S; IPC-HDBW1230E-S4; IPC-HDBW1431E and some are different manufacturer; I configure cameras from NVR not single camera configuring
