How To Calculate Storeage Requirements For Video Cameras

Video Storage Calculator, DVR / NVR Hard Drive Calculator

Utilize this video storage figurer to estimate the corporeality of hard drive space your security camera DVR / NVR needs. The hard drive adding is based on how many days of recording you lot require, the number of cameras in your organisation, camera resolution, video format and frame rate. A more than detailed explanation of the estimator fields and FAQ can be found hither.

Although this hard bulldoze calculator was primarily developed for Viewtron hybrid security photographic camera DVRs and IP camera NVRs, it can be used to guess the amount of video storage capacity needed for whatever H.264 or H.265 surveillance DVR (digital video recorder) or NVR (network video recorder).

Calculator Fields

Number of Cameras: How many security cameras will be recording on your system?
Days of Recording: How many days of recording practice you require?
Recording Resolution: What is the video resolution that your DVR / NVR will record at?
Recording Frame Rate: What is the video frame charge per unit that your DVR / NVR will record at?
Movement Activity Level: If you plan on using motility detection recording, please estimate how much move activeness you expect to accept.
Video Format / Encoding: Which video encoding does your DVR / NVR use? H.264, H.265, H.265+, H.265s.
Continuous Recording: This is an estimation of how much video storage chapters / hard drive space that you volition need for continuous 24 / 7 recording.
Move Detection Recording: This is an estimation of how much video storage capacity / difficult drive space that you volition need for motion detection recording.

Often Asked Questions (FAQ)

How accurate is this video storage calculator? CCTV Camera Pros developed this reckoner based on the video compression built into Viewtron DVR and NVRs. They use H.265 video pinch. Please note that all video hard drive calculators are an estimate. This is because the actual complexity of the video that is recorded is a gene. For example, recording in an operating environment that has a lot of movement requires more hard drive space than an area that is very still and does not change. Non only for move detection recording, but also continuous recording.
Does hard drive size and storage space mean the same thing? Yes. Hard bulldoze size, HDD size, video storage, information storage, storage space, storage capacity, and storage required all mean the same matter inside the context of calculating requirements for security DVR and NVRs.
What type of hard drive does CCTV Camera Pros recommend? We only employ surveillance rated storage devices. Video surveillance requires constant information writing to the hard drive. Standard hard drives are non recommended for this. Nosotros currently use Seagate Skyhawk hard drives.
Is H.265 a better video format than H.264? H.265 uses a better compression ratio than H.264, therefore requires less storage capacity. It does this without sacrificing video quality. H.265 is a much newer video format than H.264. Generally, there is twice every bit much storage required for H.264 compression vs H.265 compression. You can sentinel a H.264 vs H.265 video comparison here.
What is H.265+? H.265+ is a video compression / codec that is based on the standard H.265 / High efficiency Video Coding (HEVC) format. H.265+ video quality matches that of H.265 merely reduces the amount of deejay space and transmission bandwidth that is required. This is achieved past recognizing when the background is stable / static and moving objects just appear occasionally in the view. You lot tin watch our H.265 vs H.265+ video comparison hither.
Why doesn't the calculator take video quality into consideration? We have found that near people apply the highest video quality setting. That is what is causeless past the calculator.
Does this hard drive calculator work for analog CCTV DVRs? Yes. That is why we included CIF, D1, and 960H resolutions in the recording resolution setting.
Is this too a bandwidth / data rate calculator? No. CCTV Photographic camera Pros volition develop a bandwidth calculator / data charge per unit calc in the future though.

H.264 vs H.265

Watch the in a higher place video to see a comparing of H.264 vs H.265 video quality. The videos were captured using this 4mp dome IP camera. It was connected to a Viewtron IP camera NVR.
