Sub Stream check

[TheE]

Good morning!

I now have 35 cameras active with BI. To help with CPU usage, I attempted to set up a sub stream with one of the cameras. My settings are listed below; please let me know if I've missed anything or if any additional setup is required. The only thing I did at this time was add the following to the Sub, within the Stream Profile: /cam/realmonitor?channel={CAMNO}&subtype=1&authbasic={AUTH64}

How this is configured now, what is the sub stream being used for?

Sorry, two more quick questions:

1. Do I need to take any action regarding the ONVIF/camera events?
2. In the Sub Stream Guide, it instructs you to reconfigure motion detection. But within the camera, I can't find the "object travels" settings.

For large amount of camera, like 35, you would need to record continuously with sub streams and only record main stream on successful trigger.

Here is my camera setup.

Main stream: 3840x2160, 10 fps, 6144 kbps bitrate.
Sub stream: 640x360, 10 fps (matching main stream), 256 kbps bitrate.
(Use low resolution sub stream with 10-15 fps with matching bitrate. Avoid high fps on both main and sub.)

Use this guide for bitrate.

After adding a camera, go "camera setting"

## Video setting

• checked Anamorphic (force size), key in your sub stream resolution, select maching fps (Max. rate)
• recommend Hardware decode (need to try and error)

##motion / trigger

• checked "Enable motion sensor",
• click "configure"
• checked "use zone and hot spot" and configure (read Help file)

## Record (most important)

• check "video" and select "Continuous sub + triggered"
• click "file format and compression"
• (important) check "BVR", "Direct-to-disk"

## AI
- check "confirm alerts with AI" and configure

- check " Basic object detection"

Need to install codeproject AI . Hope this help.
