On the back of the ZMD-DT-SCN4 and the ZMD-DT-SCN8, the labels are confusing.

Please use the following picture to help you plug cameras into the right ports.  

• The BNC connections in the GREEN square are for your cameras.  
• The BNC connection in RED is a BNC video output to run to a display.  
• For the 8 channel, the BNC video output will be located directly above the Audio Output port.
