· Storage Mode: Five storage modes are available: Main Stream, Sub Stream, Main and Sub Stream, Main and Third Stream, Sub and Third Stream.

Note: Only certain models support all the five modes

· Capture Mode: Combinations of resolutions and frame rates.

Note: This parameter is effective only when the camera is connected to the NVR via the private protocol.

· Stream Type: Normal, main stream that is intended for scheduled recording. Event, main stream that is intended for recording triggered by events such as alarm inputs or motion detection alarms. Sub Stream, low resolution video that is intended for local or remote real-time monitoring.

· Video Compression: Video compression standard, for example, H.264, H.265. The listed options depend on the standards supported by the camera

· Bitrate Type: CBR, constant Bit Rate (CBR) is used to maintain a specific bit rate by varying the quality of video streams. CBR is preferred when limited bandwidth is available. The disadvantage is that video quality will vary and may decrease significantly with increased motion in the scene.

· VBR, when using Variable Bit Rate (VBR), video quality is kept as constant as possible, at the cost of a varying bit rate, and regardless of whether or not there is motion in the image. VBR is ideal when high quality is a requirement, especially when there is motion in the picture.

· Bit Rate(Kbps): Number of bits transferred per second. Select a value or select Custom and then set a value as needed.

· Image Quality: This parameter is effective only when Bitrate Type is set to VBR. 9 levels are provided.

· I Frame Interval: Number of frames between two adjacent I frames.

· Audio Stream: Enable or disable audio stream

· U-Code: The advanced mode achieves higher compression ratios.
