The technical starting position
A too low bitrate can lose details in busy scenes, while a too high setting can unnecessarily load storage and network. The right choice varies depending on the viewing angle.
advice
Choose NVR recording quality and bitrate
High resolution alone does not guarantee usable evidence; the entire recording setting determines how much detail remains when moving and searching.
What you calculate or measure
Determine what the camera should show: overview, face, vehicle, or a specific action. Also view light, motion, available storage, and network capacity.
The intervention that fits
Set quality per channel and avoid having less important broad overview images receive the same load as a critical entry. Change one setting at a time when reporting complaints.
Proof that it works
Compare an recorded test with live footage on the relevant route and check the impact on the storage period. Record the chosen profile and reason.
Frequently asked questions
Is maximum bitrate always the best?
Not as storage, network or the camera's purpose becomes unbalanced by it.
Why do they differ per camera?
A driveway and a technical area have different visual and evidence requirements.
