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.

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.
