Applies to Models: All Hanwha Multi-Sensor Cameras that use plug-in modules

Summary:

This article will go over some causes of video loss on the channels of some of our multi-sensor cameras.

Explanation of Behavior:

• Normal channel booting looks like the following:

Resolution:

• Make sure the firmware is up to date

Note: If your camera is integrated with a third-party VMS, always use their
recommended firmware

• Some multi-sensor units have status indicator lights Figure 2
• If the indicator is red this indicates a problem with the module in that socket Figure 2
• Green is a normal function Figure 2

Note: Some cameras have status indicator LEDs for the modules, some
stay on continuously, and some turn off after about a minute in order
to not cause a reflection inside of the dome.

• Figure 3 has an example of Sensor module boot failure
• If reseating the module and initializing the camera does not clear the error, try moving one of the working sensors in the other sockets to the module socket reporting errors Figure 3

• If the problem follows the module, then the module is bad
• If the problem always exists on the same channel. Then the camera body is not functioning normally.
