 Streaming: Configuring Video streaming settings as below:

The RTSP command code as below: Main streaming: RTSP://IP

Address:554/media/live/1/1 Sub streaming: RTSP://IP

Address:554/media/live/1/2





 Source Resolution: Select video main streaming resolution from the drop

menu.





 Streaming ID: Streaming 1 means is the “ Main Streaming “ that for the

recording purpose. The streaming 2 means is the “ Sub streaming” that is

for the remote viewing from Internet when bandwidth is not enough or split

video display to reduce the system loading.





 Video Encode: The Video Encoding standard can be set to H.264 or MJPEG.

You can set the profile level to High Profile, Main Profile or Basic Profile

for H.264 encode.





 Audio Encode: There are G7.11 u Law /a Low compression. G.711ulaw

selectable.





 Resolution: Choice the video streaming resolution for display and recording.





 I-Frame interval: It is the least compressible but doesn't require other video

frames to decode. Less number of I-Frame intervals will get less size of

video streaming, but the video quality will be worse when image change rate

is high.





 Frame rate: The frame rate is to describe the frequency at which the video

stream is updated and it is measured by frames per second (fps). A higher

frame rate is advantageous when there is movement in the video stream, as it

maintains image quality throughout.





 VBR (Variable Bit Rate): VBR files vary the amount of output data per

time segment. It allows a higher bitrates (and therefore more storage space)

to be allocated to the more complex segments of media files while less space

is allocated to less complex segments.





 CBR (Constant Bit Rate): The rate at which a codec's output data is

constant. CBR would not be the optimal choice for storage as it would not

allocate enough data for complex sections (resulting in degraded quality)

while wasting data on simple sections.





 Bit Rate mode: Set the max. Bitrate to 200~12000 Kbps. The higher value

corresponds to the higher video quality, but the higher bandwidth (file size)

is required.
