Hello, I have a problem with a Hikvision NVR, DS-7608NI-E2/8P/A. Every time I connect it to the monitor, the date is set to 01.01.2004. The current firmware is V.3.4.6. Build 160405. According to the recording date and time, the last recording in the NVR is from 09.mar.2022 – 12:44:21. Recordings from March 9, 2022 until the end of 2023 are missing. Some videos have the date 2005 in the image, but they obviously come from 2022-2023. Is it possible to find out from the log file whether the date and time were intentionally changed, or could it be caused by outdated firmware? Is it necessary to update the camera firmware when updating the firmware of this model? What are the most common problems that outdated firmware in the NVR can cause?
Thank you
