CCTV System Calculators
How to use the storage calculator
- Enter the number of cameras and the number of microphones
- Select the camera resolution
- Select the type of compression: H – High Quality M – Medium L – Low Quality
- Enter recording frame rate (FPS) and the number of days
- Select the type of scene that the camera is monitoring. Complex environments with high motion will reduce the amount of compression attainable
- Select the percentage of day that the cameras / mics are expected to record
📡 IP Camera Bandwidth Calculator
Estimate the total network bandwidth required for your IP camera system.
Bandwidth Requirements
–
Mbps per camera
–
Total bandwidth (Mbps)
–
Recommended switch port speed
–
Data per day (GB)
* Estimates based on typical CBR bitrates. Actual bandwidth varies with scene activity, lighting changes, and encoder settings. Add 20% overhead for network management traffic and allow for burst peaks up to 1.5x the calculated value.
💾 CCTV Hard Drive Storage Calculator
Calculate the total NVR storage required for your camera system based on resolution, recording hours, and retention period.
Storage Requirements
-
Storage per camera
-
Total storage needed
-
4TB drives needed
-
8TB drives needed
* Estimates assume constant recording at the selected settings. Motion-triggered recording can reduce actual storage by 30–60%. NVRs typically require 10–15% additional overhead — add one drive above the calculated minimum. Veilux NVR systems support 2TB to 16TB surveillance-grade HDDs.
