Help DS-2CD1327G0-L, I had V5.7.2 build 211230 firmware  , and I changed it with the new V5.7.12 build 220819 I downloaded it from the global hikvision, I knew that I'm making a mistake because firmware's from global hik are always bad. Now I have many problems.

Camera is now unstable, it will lose connections to nvr. Also, now if I enable motion event, I will have cyclic 1-minute breaks in continuous recording, also live view outside of direct camera web-gui is unstable and often will be lost.

Also if I don't enable  "Dynamic Analysis for Motion" I will not have motion markers on the recording. Enabling "Dynamic Analysis for Motion" will make the camera highly unstable.

Thanks god, I changed firmware just on one camera. The question is could I revert back to the old firmware, or can I find out some which works?

 

My NVR is DS-7608NI-E1 / A, and I also made a mistake changing the firmware to the latest global V3.4.106 build 191009, also now NVR is unstable; if I use fluent on 5 cameras in NVR live view, it will cause it to freeze and stop recording. Reverting cameras to balanced will make NVR more stable.

 

I can't believe this.
