  Parameters 
Description 
Encoder Type
Select the encoder’s compression type. 
MPEG-4 / MJPEG / H.264 
Resolution 
Select the video resolution of the IP device. 
Frame rate 
 Select the available frame rate from the drop down menu. 
Video Bit 
Rate Mode 
Select the video bit rate mode. 
 Constant Bit Rate: The bit rate remains constant at all 
conditions. 
 Variable Bit Rate: The video bit rate will vary based upon 
scene complexity and amount of movement. The quality will 
remain the same. 
Quality 
When encoder type is MPEG4 or H.264, and video bitrate mode 
is “Variable Bit Rate” Select the quality value from High / 
Medium / Low 
GOP Length
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. 
Frame rate 
Select the available frame rate from the drop down menu. 
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 Bit 
Rate Mode 
Select the video bit rate mode. 
 Constant Bit Rate: The video bit rate remains constant at all 
conditions. 
Variable Bit Rate: The video bit rate will vary based upon scene 
complexity and amount of movement. The quality will remain 
the same. 
Video Max 
Bitrate 
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
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. 
Frame rate 
Select the frame rate for each profile by choosing from the drop
