6.4 SUB – MAIN SWITCHING DUAL STREAM
The new dual stream function enables fast image transmission even with reduced network bandwidth. The
second (sub) stream works independently from the recording settings.
There are 2 compression methods available: MJPEG or H.264.
Thanks to the optimized compression method, a faster transmission is obtained using H.264.
Example (16-channel DVR):
Sub stream: Average streaming data volume for 16x view: 1,8 Mbit/s
Main stream: Average streaming data volume for 16x view: 12 Mbit/s
(all cameras set to: resolution 704x576, highest quality, 6,25 IPS)
