ag22plug 0 Posted January 27, 2011 Hi All, I have one camera which switches to IR and one which doesnt ; so apart from testing them how do you know which type you have when you are buying a board camera ? Does the term HAD have anything to do with it ? cheers Chris. Share this post Link to post Share on other sites
Soundy 1 Posted January 28, 2011 Depends what you mean by "switches to IR". Some cameras have a "night mode" when they switch from color to B&W. Some have IR LEDs that add extra illumination when they're in night mode. It's easy to tell those from looking at them. "HAD" has nothing to do with the difference.
