IR LED 4-Pin Pinout

Recommended Posts

I have disconnected and removed the 4-Pin IR LED Board from a 1080p HD Lorex Camera (LBV2531W). The camera is now in constant Night (B/W) Mode, even during the day. I can change this in the DVR Setup but I would prefer to keep the automatic mode.

 

The board had a single 4-Pin connector between the camera board and the IR LED ring. I am assuming that 2 of the 4 pins are for the IR/LEDs (V+ & GND) and the other 2 pins are for the photoresistor. Is there a way to connect just a standard photoresistor between 2 of the pins as a working bypass without the need for the IR Led board. If this is possible, is there a way for me to tell what 2 pins I need to connect it to? On the Board Pin 1 is marked as LED. Not other pines are marked.

Hi. You can do it from the menu.

 

If you go camera settings you will see two columns

 

Right is day time settings left is night settings ..... Tick the box on night setting and then enter the time you want it to switch to B/W and set time you want to go colour .... Hit save then apply
