Performance Series IP Camera Software Configuration Guide

In this way, you may set up an ROI window as a privacy mask by covering a protected area
using an ROI window, while the rest of the screen becomes the non-interested area. You
may then configure the non-interested area to have a high image quality, or vice versa.
Bit rate control
Constrained bit rate
A complex scene generally produces a larger file size, meaning that higher bandwidth will be
needed for data transmission. The bandwidth utilization is configurable to match a selected
level, resulting in mutable video quality performance.
• Target quality: Select a desired quality ranging from Medium to Excellent. If you select
Customized, you can enter a value to specify the quality.
• Maximum bit rate: Select a bit rate from the dropdown list. The bit rate ranges from
20kbps to a maximum of 40Mbps. If you select Customized, you can enter a value to
specify the maximum bit rate.
• Policy: If Frame rate priority is selected, the camera will try to maintain the frame rate per
second performance, while the image quality will be compromised. If Image quality
priority is selected, the camera may drop some video frames in order to maintain image
quality.
Fixed quality
All frames are transmitted with the same quality.
• Quality: Select a desired quality ranging from Medium to Excellent. If you select
Customized, you can enter a value to specify the quality.
• Maximum bit rate: Select a bit rate from the dropdown list. The bit rate ranges from 1
Mbps to a maximum of 40Mbps. If you select Customized, you can enter a value to
specify the maximum bit rate.
The Maximum bit rate setting in the Fixed quality configuration can ensure a reasonable
and limited use of network bandwidth. For example, in low light conditions where a Fixed
quality setting is applied, video packet sizes can tremendously increase when noises are
produced with electrical gains.
Configuring Audio Settings
Go to Setup Camera Setup Audio.
