We are using Hikvision dvr.We usually switch off the dvr for 12 hours daily during night time.When we turn on the dvr next day it starts recording from the time when it switched off .e.g.if i switch off the dvr on 10-1-23 10p.m. and turn on the dvr next day 11-1-23 9am, it starts recording from time 11-1-23 10pm onwards also there is no indication of dvr switched off in that time zone.I also changed the cmos battery still the problem persists. Please do the needful.
