I have a hikvision analog dvr ( DS-7204HFI ) I have setup the dvr at my home to install it in my office next week. i manually setup the clock exactly with my pc's time (which is updated from windows time server) and then turned off the dvr , unplugged it and i didnt plugged it for 1 week after 1 week in my office i observed than dvr's time is not exactly as same as my pc's time . it seems than dvr's clock running faster than normal when it is unplugged please help me what can i do with this issue ??

dvr Cmos battery is same as pc??? wouldnt it damage dvr software? it is on the board or i have to remove the board??

is there any problem with my dvr's cmos battery ?

is this problem exist in other dvrs? which ntp server (ip and port) do you prefer?

dvr's time goes faster when unplugged not slower

so my dvr isnt faulty? the only solution is NTP??

unfortunatly i dont have internet access in my office. is this issue normal ? how can i avoid it?
