Can Hikvision detain button cell when the hard disk video recorder is turned on?

I can't.

When the video recorder is not connected to the external network, it obtains the system time through its own button cell RTC. If the battery is dead, poorly contacted or damaged, it cannot provide the correct time for the video recorder. If the time of the monitoring screen is changed to x, month, x, 2000 or close to the identification date of the video recorder upgrade software, it is most likely that the battery is dead or damaged.

Camera battery is an indispensable part of the camera and the heart of the camera. Without a battery, the camera can't work and can't take pictures and videos. Therefore, attention should be paid to maintaining the camera battery during normal use to ensure its life.
