Bit rate is measured in bits per second. In IP video it usually refers to the bit rate from an IP camera. Controlling the bit rate controls the bandwidth needed to transfer data from the camera. The camera processor will automatically limit the maximum bit rate sent from the camera to the bit rate setting selected.
Biometrics refers to identity verification using physical traits like fingerprints, face, or iris scans. Integrated with CCTV, it enhances access control and security.
