Calcula almacenamiento CCTV y NVR según cámaras, bitrate, resolución, retención y grabación para dimensionar videovigilancia mejor.
Esta calculadora de almacenamiento CCTV está pensada para equipos que dimensionan NVR, servidores VMS y políticas de retención antes de comprar. Responde a la intención principal de esta página: calculadora de almacenamiento CCTV y NVR.
Úsala para modelar almacenamiento según cámaras, resolución, bitrate, códec, días de retención y modo de grabación, y comprobar si el diseño soporta la ventana de grabación requerida.
Define cámaras, resolución, FPS y códec según el diseño real.
Elige el modo de grabación, como continuo, por movimiento o programado.
Introduce días de retención y cualquier sobrecarga de formateo o 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.
Solo Estimación de Ingeniería. La tasa de bits varía según la complejidad de la escena.
Validar las especificaciones finales con herramientas del fabricante.
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.
