Parameters

Description

Encoder Type

Select the encoder‟s compression type.

MPEG-4 / MJPEG / H.264

Resolution

Select the video resolution of the camera between 4M (2032 x 1920),

2M 1080p (1920 x 1080), 1M 720p (1280 x 720) and VGA (640 x 480)

Frame rate

Select the available frame rate from the drop down menu.

Video Bit Rate

Mode

Constant Bit Rate: The bit rate remains constant at all conditions,

Video quality will be better when image is still. Large amount of motion

or complex scene will degrade quality slightly.

Variable Bit Rate: The video bit rate will vary based upon scene

complexity and amount of movement. The quality will remain the same.

Quality

(Variable Bit

Rate Only)

When encoder type is MPEG4 or H.264, and video bitrate mode is

“Variable Bit Rate” Select the quality value from High / Middle / Low

GOP Length

(Variable Bit

Rate Only)

When encoder type is MPEG4 or H.264. and video bitrate mode is

“Variable Bit Rate”. Select the Interval between two I-frames. This is also

called GOP Length. (Group of Picture). Default value is one I frame per

second. The maximum length of GOP is limited to 60.

Video Max

Bitrate

(Constant

Bitrate only)

This puts a hard cap on the maximum bit rate allowed in any given

second of video streaming. Assigning a limited bit rate may result in a

few dropped frames rate when the stream data overflows the allowed

bit rate. Doing so will also disable Bit Rate setting below.

Video Bitrate

(Constant

Bitrate only)

This is the target bitrate that the camera will attempt to provide when

using Constant Bitrate mode. The actual value will fluctuate slightly

based on scene changes.
