The RLC-423 camera, as well as the RLC-423WS and RLC-423S, has 6 LEDs in total, when at night, different amount of LEDs will light up depending on the different focus position of the camera.
If you find that the IR LEDs of your camera are partly lit, don't worry, there is nothing wrong with your camera.
There’re three modes of IR LEDs for RLC-423 depending on the different focus position as explained below:
1. Two IR LEDs on the bottom are lit.
Please note these 2 LEDs are high beam lights, if the camera is focusing at a far scene, these 2 LEDs will light up like picture below.
2. Four LEDs on the top are lit.
Please note that these 4 IR LEDs are Low beam lights, if the camera is focusing at a close position, these 4 IR LEDs will light up as shown in the picture below.
3. All the 6 IR LEDs are lit.
if the camera verify the current scene is in the middle of the focus position, all the LEDs will light up as shown in the picture below.
The camera will light different amount of LEDs according to its different focal length, if there are only 2 or 4 LEDs are on, it does not mean the camera is defective but indicate the camera is on particular focal length.
