The short answer
One continuous Mbps is about 10.8 decimal GB per day. Multiply by streams, days and actual recording duty cycle, then check the result against real files.
Work through the checks
Use ONVIF-reported media profiles where available, and record the selected profile token. Profiles can differ in resolution, codec, audio and PTZ associations.
Estimate decimal GB per day as total Mbps × 10.8, then multiply by days and recording duty cycle. Add practical headroom and measure real files because variable bitrate changes with motion.
Check the actual recording volume, available space and write permission. Confirm the folder belongs to the intended disk rather than an unavailable USB drive or a redirected system folder.
If recording is available in the installed build, capture a short authorized test event. Confirm a new local file is created, grows as expected and can be reopened after recording stops.
4 Mbps × 10.8 × 3 cameras × 7 days = 907.2 GBWhat to verify
Separate the chosen retention period from actual cleanup behavior. Test the installed app’s available storage controls with disposable footage before relying on automatic deletion.
