What causes bandwidth issues with 8MP cameras on a 4-channel NVR?

Bandwidth for 8MP Cameras

If you're experiencing maximum bandwidth issues with your 8MP cameras, follow the recommended settings provided by Hikvision to maintain optimal performance while preserving full resolution. Here’s how to set up your camera streams effectively:

Recommended Camera Settings

1. Main Stream (Normal) Settings:

   • Resolution: 8MP
   • Bitrate Type: Variable
   • Frame Rate: 15 fps
   • Maximum Bitrate: 6144 kbps
   • Video Encoding: H.264, H.264+, H.265, or H.265+
   • I Frame Interval: 40 (if applicable)

2. Main Stream (Event) Settings:

   • Resolution: 8MP
   • Bitrate Type: Variable
   • Frame Rate: 15 fps
   • Maximum Bitrate: 6144 kbps

3. Sub Stream Settings:

   • Resolution: Choose the highest option but keep it lower than 1920 x 1080
   • Bitrate Type: Variable
   • Frame Rate: 15 fps
   • Maximum Bitrate: 768 kbps
   • Video Encoding: H.264

If your camera does not have I Frame interval settings, you can disregard that particular setting.

Troubleshooting Decoding Issues

If you encounter decoding problems (e.g., low resources when viewing multiple cameras simultaneously), follow these steps:

1. Access the NVR Local Monitor.
2. Navigate to Configuration > Live View > Layout > More Settings.
3. Change the Stream Type from Auto to Sub Stream. This setting ensures that the NVR uses the sub stream for multi-view mode while retaining the main stream for single live views.

By implementing these settings, you can manage bandwidth usage effectively while ensuring that your 8MP cameras operate smoothly.
