SAS-UK 0 Posted January 19, 2018 Hi guys, I recently bought the following system: 4 x DS-2CD2T55FW-I5 (Hikvision 5MP POE IP 50m EXIR Bullet) 1 x 4TB Seagate SkyHawk HDD 1 x DS-7604NI-K1/4P (Hikvision 4 Channel POE NVR) The issue I am having is that the cameras only record continuously for around 22/23 days, I need 30 days. I used the HikVision calculator and it says I only need 3TB to achieve this. However I have 4TB and can only manage 22/23 days. The cameras are H.265+ compatible, which I assumed was the best way to record on these 5MP cameras but am now considering playing withe the BitRate as I'm not sure what else I can do besides put more HDD space in? Any help would be much appreciated. Kind regards, SAS. Share this post Link to post Share on other sites

SAS-UK 0 Posted January 24, 2018 Hi. Why 30 days ? 22 days from 4 of 5mp cameras is good Hi Tom! Thanks for the reply! 30 days is what we're aiming to achieve because thats what they're requested. Am I right in thinking dropping the FPS could improve the record length? Also checking / updating to the latest firmware and turning on H.265+ rather than dropping the bitrate as H.265+ is more efficient at compressing as opposed to having it off and fixing the bitrate so say 3k?

Kind regards, SAS. So are you not using H.265+? Make sure you select that video profile in your recorder/VMS. Share this post Link to post Share on other sites
