Live Video Image Delay and Freezing

Applicable Models

This fault may occur on the following IPC models:

• IPC6122-P
• IPC6122-D
• IPC6112-P
• IPC6112-D
• IPC6221-VRZ-SP
• IPC6221-VRZ
• IPC6211-VRZ

Symptom

When users view live video on the web client of a camera, the CPU usage of the IPC reaches up to 100%, and image delay and freezing occur on the live video.

Possible Causes

• On the camera: Dual streams are enabled on the camera; the primary stream resolution is 1080p.
• On the platform: The TCP protocol is used as the transmission protocol; the resolution is 1080p; the bit rate is 6144.

Solution

1. Modify parameters on the camera and platform.
   • Modify parameters on the camera.
     • Set Stream type to Primary stream.
     • Set Resolution to a value less than 1080P.
   • Modify parameters on the platform.
     • Set Transmission Protocol to UDP.
     • Set Resolution to a value less than 1080P.
     • Set bit rate to a value less than 4096.
2. Check whether the fault is rectified.

   If yes, no further operation is required. If no, contact your service provider.
