Securame 0 Posted January 8, 2014 If you are going to have it online, make it sync the time with NTP. Share this post Link to post Share on other sites
shockwave199 0 Posted January 8, 2014 Absolutely that is the best way. I have mine [dahua] update every 30 min. Rock solid time. Share this post Link to post Share on other sites
amani92 0 Posted January 8, 2014 unfortunatly i dont have internet access in my office. is this issue normal ? how can i avoid it? Share this post Link to post Share on other sites
shockwave199 0 Posted January 8, 2014 In my experience it's normal for the clocks to start running slow by as much as two minutes and more as time goes on. Without auto updating, you'll have to keep an eye on it and manually nudge it every so often. Share this post Link to post Share on other sites
Numb-nuts 1 Posted January 8, 2014 Electronic equipment made on a budget to a particular market is bound to change it's time being affected bu other devices etc. Hence the introduction of time servers. Originally intended for the computer market. Share this post Link to post Share on other sites
amani92 0 Posted January 9, 2014 so my dvr isnt faulty? the only solution is NTP?? Share this post Link to post Share on other sites
amani92 0 Posted January 9, 2014 dvr's time goes faster when unplugged not slower Share this post Link to post Share on other sites
Securame 0 Posted January 9, 2014 so my dvr isnt faulty? the only solution is NTP?? Well... The solution would also be NOT unplugging the DVR, then Share this post Link to post Share on other sites
amani92 0 Posted January 9, 2014 is this problem exist in other dvrs? which ntp server (ip and port) do you prefer? Share this post Link to post Share on other sites
Securame 0 Posted January 9, 2014 is this problem exist in other dvrs? which ntp server (ip and port) do you prefer? I never bothered checking time on DVRs that are not connected. I use es.pool.ntp.org because I am in Spain, port 123. http://www.pool.ntp.org/en/use.html Share this post Link to post Share on other sites
amani92 0 Posted January 9, 2014 is there any problem with my dvr's cmos battery ? Share this post Link to post Share on other sites
Numb-nuts 1 Posted January 9, 2014 Port 123 is the common port on MOST time servers. Re your CMOS battery, wouldn't hurt to replace it and then monitor how well it keeps time. Share this post Link to post Share on other sites
amani92 0 Posted January 9, 2014 dvr Cmos battery is same as pc??? wouldnt it damage dvr software? it is on the board or i have to remove the board?? Share this post Link to post Share on other sites
shockwave199 0 Posted January 9, 2014 If it's a new dvr, don't get involved in something silly. Plug the dvr back in and update the time and leave the thing on and recording like it's meant to do. End of story. Don't complicate matters. Share this post Link to post Share on other sites

End of story. Don't complicate matters. He's right, leave it alone, I forgot you aren't a technician. If you want really accurate time that much, get a broadband connection and connect to a NTP. Can't imagine why you wouldn't connect to internet. Share this post Link to post Share on other sites
