I bought this camera to experiment with, mostly based on the fact that it is considered to be a "Night Vision IR" camera. Now that I've received it, I am having a hard time finding out certain information about it.
Specifically, why does it have the extra pair of wires going to the lens cover housing? I have other similar PCB cams that lack the wires and have no claims of IR Night Vision. The wires go to a to wire connection on the PCB labelled "IR CUT", which says to me that it somehow filters IR. Now, I know that practically any CMOS camera is sensitive to IR light, but they are fitted with IR filtering lenses in order to give better (clearer) pictures in the visible spectrum.
If I hook it up to a transmitter, it works just like a visible spectrum camera does. I see no benefits when using it in the dark. I am thinking I somehow need to activate the IR CUT (or rather I suppose I would be deactivating it). Do I just simply apply a voltage to those pins?
If those wires do activate/deactivate the filter, how does it work?
There is another two pin connector on the PCB labelled CDS (images can be found at the link). Would they be for a photoresitor? How can I use those pins? I have searched for spec sheets online, but haven't had any luck. I don't really know what control chips it would be using. Does anyone have any similar equipment whose spec sheets could offer some hints?
