ONVIF Camera Compatibility › Tools
CCTV tools for planning and wiring
Two free calculators that answer the two most common pre-purchase questions: how much bandwidth and storage will my cameras need, and what's the exact RTSP URL for the cameras I already own.
IP camera bandwidth & storage calculator
Camera count × resolution × codec → total ingest (Mbps), NVR storage for any retention (TB), and how many 4/8/16 TB drives that is. Continuous vs motion-only recording modes included.
Camera RTSP URL finder
Paste-ready main + sub-stream RTSP URLs for Hikvision, Dahua (incl. Imou/Amcrest), Reolink, Tapo, UniFi, Wyze, Axis, Foscam — each sourced from the vendor's own documentation, with brand-specific warnings.
When to use which tool
Planning a system from scratch? Start with the bandwidth & storage calculator so the NVR, switch and drive purchases match the cameras you actually want. Buying cameras to add to an existing NVR? The RTSP finder builds the exact stream URL from the camera's brand, then check the NVR compatibility matrix for how that NVR adopts third-party cameras, and verify the model's ONVIF certification in the database.
