Dahua Infrared LED Illuminator Wiring Guide

Power Cable

The power cable is a 22AWG*3C cable with three conductors: yellow-green, blue, and gray.

  • Blue Wire — Connect to the AC 220V Neutral (N).
  • Yellow-Green Wire — Connect to Ground (Earth). This wire must be properly grounded to enhance device reliability; otherwise, the unit will lose its lightning protection capability.
  • Gray Wire — Connect to the AC 220V Live (L).

Signal Cable

  • Yellow Wire — Strobe trigger signal EX+.
  • Blue Wire — Strobe trigger signal EX-.
  • Green Wire — Flash trigger signal FLASH+.
  • Gray Wire — Flash trigger signal FLASH-.
  • Orange Wire — Strobe output signal STOUT+.
  • Brown Wire — Strobe output signal STOUT-.
  • Red WireRS485_A.
  • White WireRS485_B.
  • Black WireGND.

Wiring the Strobe/Flash Illuminator to the Camera

Step 1:

Connect the illuminator’s strobe trigger wires EX+ (Yellow) and EX- (Blue) to the camera’s strobe trigger interface F1+ and F1-.

Step 2:

Connect the illuminator’s flash trigger wires FLASH+ (Green) and FLASH- (Gray) to the camera’s flash trigger interface F7+ and F7-.

Note: The camera provides a total of seven interfaces.

  • F1–F6: Default strobe trigger interfaces
  • F7: Default flash trigger interface

Wiring Multiple Flash Illuminators to the Camera

Step 1:

Connect the first illuminator’s flash trigger wires FLASH+ (Green) and FLASH- (Gray) to the camera’s default flash trigger interface F7+ and F7-.

Step 2:

Connect the first illuminator’s flash output wires STOUT+ (Orange) and STOUT- (Brown) to the second illuminator’s flash trigger wires FLASH+ (Green) and FLASH- (Gray).

Subsequent illuminators can be cascaded in the same manner until all flash units are interconnected.
