8MP Cameras on 4CH – Bandwidth issues?

Some customers have advised they are getting max bandwidth issues with their 8MP cameras. Below are recommended settings from Hikvision to ensure you don’t have bandwidth issues while retaining the full 8MP resolution.

1.      Main stream (normal) resolution is still 8MP, Bitrate type is Variable, Frame rate is 15, Max. Bitrate is 6144 kbps, Video encoding H.264, H264+ or H265 or H265+, I frame interval is 40. 

2.      Main stream (Event) resolution is still 8MP, Bitrate type is Variable, Frame rate is 15, Max. Bitrate is 6144 kbps, 

3.      Sub stream resolution choose the highest one but lower than 1920 * 1080, Bitrate type is Variable, Frame rate is 15, Max. Bitrate is 768 kbps, Video encoding H.264.

If you don’t have I Frame interval settings, please kindly disregard.

NOTE – If you have decoding issues eg. no resource when viewing cams at the same time:

please go to NVR local monitor, Configuration – Live view – Layout – More settings. Change Stream Type from Auto to Sub stream. So in multi-play mode it uses sub stream while viewing single live view it uses main stream resolution.
