How I optimized my RTSP camera

Log in to your camera's internal settings

You will need to access the camera's internal settings. This can either be done through the web browser or through a third party tool like an ONVIF Device Manager. Once you have access find and change these option to the settings shown as follows.

• Framerate (FPS) :
  • High : Between 10 to 15
  • Low : Between 2 to 5
• H264 Profile : Baseline or Main
• I-frame interval :
  • Set to Match your set FPS or as lowest number possible. (FPS is the first value mentioned in this list)
  • Knowing how to tune this is important for keeping low processing power and Recording based on an Event, like Motion.
• Bit Rate Type :
  • VBR : For Good Network Conditions
  • CBR : For Bad Network Conditions, Broken images from streams
  • Some cameras do not allow changing this. Instead they may offer different Stream URLs to access VBR or CBR video streams, like Reolink.
• Bit Rate :
  • If camera is a 2MP (Megapixel) and below : Between 256kbps and 1Mbps
  • 2MP to 5MP : Between 1Mbps and 2.5Mbps

Ran on a Jetson Nano

43 Cameras with only Stream and Recording, No Detection Engines enabled. 45% CPU Utilization .

The Jetson Nano required a power adapter with more amps. A barrel jack 5V 10A adapter was used for this test.

ONVIF Device Manager

If you don't have the camera's internal options easily accessible to you then with an ONVIF Device Manager you can edit them.

Windows ONVIF Device Manager

Recently Shinobi has made improvements to ONVIF device management, you may select ONVIF from the top left menu and scan for cameras on the network, additionally you can have Shinobi add them all at the same time.
