Estimate video surveillance storage requirements and network uplink load.
A CCTV and NVR storage calculator helps security professionals and system integrators estimate daily data generation and bandwidth requirements. By configuring camera counts, resolution, frame rate, and compression, you can accurately provision hard drives and network uplinks, preventing costly system bottlenecks or insufficient retention times.
H.265 (HEVC) offers up to 50% better data compression than H.264. This significantly reduces both required hard drive space and network bandwidth for high-resolution cameras.
Yes. Variable Bit Rate (VBR) recording means cameras capture more data during high motion. Estimating activity accurately is crucial for avoiding premature footage overwriting.
RAID 5 or RAID 6 are commonly recommended for video surveillance. They offer a good balance of storage efficiency and fault tolerance against drive failure.
Total bandwidth is the sum of the bitrates from all cameras streaming to the NVR. It is typically measured in Megabits per second (Mbps).
