Go to Image


resolution, frame rate, bitrate type, video quality and so on subject to the actual
network condition.
Three video streams and one thermal stream can be adjustable.
Resolution : The size of image.
Frame rate : The higher the frame rate, the video is smoother.
Bitrate type : CBR and VBR are optional. Bitrate is related to image quality. CBR
means that no matter how much change is seen in the video scene, the compression
bitrate will be kept constant. VBR means that the compression bitrate will be adjusted
according to scene changes. For example, for scenes that do not have much
movement, the bitrate will be kept at a lower value. This can help optimize the network
bandwidth usage.
Bitrate : it can be adjusted when the mode is set to CBR. The higher the bitrate, the
better the image quality will be.
Video Quality : It can be adjusted when the mode is set to VBR. The higher the image
quality, the more bitrate will be required.
I Frame interval
: It determines how many frames are allowed between a “group of
pictures”. When a new scene begins in a video, until that scene ends, the entire group
of frames (or pictures) can be considered as a group of pictures. If there is not much
