Storage Retention Calculator
Estimate continuous-recording capacity from the configured average bitrate. The planned figure includes a 10% reserve.
PoE Power Budget Calculator
Check sustained camera load against the switch or NVR PoE budget. Aim for no more than 80% planned utilisation.

Secure CCTV deployment workflow
Plan coverage
Select lens, mounting height, lighting and pixel density for each scene.
Design the network
Reserve addresses, calculate PoE and isolate cameras with a dedicated VLAN.
Size recording
Set bitrate, schedule and retention before choosing surveillance storage.
Harden devices
Change credentials, update firmware and disable unused services.
Commission
Verify daytime, night, events, timestamps, recording gaps and recovery.
CCTV storage and PoE questions
How much CCTV storage do I need?
Storage depends on camera count, average bitrate, recording hours, retention days, codec and scene activity. Plan additional reserve for filesystem overhead and bitrate variation.
How much spare PoE capacity should a CCTV system keep?
A practical design target is to keep sustained camera load at or below about 80 percent of the switch or NVR PoE budget, with extra allowance for infrared illumination and device startup.
Does H.265 always use half the storage of H.264?
No. Actual savings vary with the camera, scene movement, resolution, frame rate, image quality and encoder implementation. Use the configured average bitrate for planning.
Is it safe to share an RTSP URL?
No. An RTSP URL can contain a camera username and password. Generate it only on a trusted device, avoid screenshots or chat sharing, and use a limited-permission account where supported.
Should IP cameras be placed on a separate network?
For business and larger residential deployments, isolate cameras with a dedicated VLAN or network, restrict internet access and allow management only from authorised systems.
