IC Realtime - Addressing Invalid Camera Format on IC Realtime FUSION Series XVR

In the FUSION 5x3 and 5x4 generations, BNC inputs are connected to a single Dual Channel ADC (Analog-to-Digital Converter Chip). 

If you have all the same camera formats on any of the DVRs, there is no issue, this issue only occurs when you mix formats across channels that use the same chip. 

Explanation of the Issue 

Why It Occurs: 
This issue arises when two channels are connected to a Dual Channel ADC using different camera formats, such as standard definition (SD) and high definition (HD) cameras.

For example, on a FUSION-5x4-832-i where Channel 1 and Channel 3 are paired together, if Channel 1 is connected to a HDCVI camera and Channel 3 is connected to a CVBS camera, Channel 3 will display the error message but if a HDCVI camera is connected to Channel 3 there will be no error message. 

Example Scenario of FUSION-5x4-832-i where Channel 1 and 3 are paired together: 

• Channel 1: HDCVI (HD camera) 

• Channel 3: CVBS (SD camera) 

• Result: Channel 3 shows "Invalid Camera Video Format." 
  
  
  
  • Avoid Using Dual Channel ADC with Mixed Formats: 
    Do not connect two channels using different camera formats (SD and HD) to the same Dual Channel ADC to prevent incompatibility issues. 
  • Use Compatible Camera Formats: 
    Ensure that both cameras connected to a paired BNC channel are of the same format. 
  • Refer to Channel Pairing Table: 
    Always consult the following table to understand which BNC channels are paired on the same Dual Channel ADC across different models.
