Loading tool...
Calculez le stockage CCTV et NVR selon caméras, débit, résolution, rétention et enregistrement pour bien dimensionner le système.
Ce calculateur de stockage CCTV aide les équipes à dimensionner NVR, serveurs VMS et politiques de rétention avant achat. Il cible l’intention la plus pertinente pour la page: calculateur de stockage CCTV et NVR.
Utilisez-le pour modéliser le stockage selon le nombre de caméras, la résolution, le débit, le codec, les jours de rétention et le mode d’enregistrement afin de vérifier si le design tient la période requise.
Définissez le nombre de caméras, la résolution, le FPS et le codec du design réel.
Choisissez le mode d’enregistrement: continu, sur mouvement ou planifié.
Saisissez les jours de rétention et l’overhead lié au formatage ou au RAID.
Add headroom for RAID, night noise, weather, busy gates, and future camera expansion.
Use the calculated TB figure as the starting point for a design review when the project includes perimeter alarms or many cameras.
Estimation d'ingénierie uniquement. Le débit varie selon la complexité de la scène.

Multiply camera count by average bitrate, recording seconds per day, and 30 days, then divide by 8 to convert bits to bytes and by 1,000,000 to estimate terabytes. Add headroom for RAID, formatting, metadata, night noise, and camera expansion.
It depends on the encoded bitrate, not resolution alone. A 4K H.265 camera recording continuously at 8 Mbps for 30 days uses about 2.6 TB before RAID and overhead; at 4 Mbps it uses about 1.3 TB.
Vendors often advertise disk capacity in TB, while operating systems may show TiB. For procurement, calculate in TB and keep extra headroom so the TB/TiB difference does not break the retention target.
Average bitrate, recording mode, retention days, scene motion, night noise, frame rate, codec, and camera count usually change storage more than the camera resolution label by itself.
H.265 usually reduces storage at similar quality, but actual savings depend on the camera encoder, scene complexity, VMS compatibility, GOP settings, and whether the client systems can decode it reliably.
Request a design review when the system protects a commercial perimeter, needs 30-90 day retention, includes many cameras, or must tie video retention to alarm verification and operator response.
Yes. Use it to estimate storage for cameras that verify fence-line alarms, gates, yards, substations, or other perimeter zones, then validate the design against actual bitrate samples and response workflows.
