infrared from one trail camera interfere with the infrared from another???? for example lets say I have 2-3 cameras set up over one spot the camera is activated but so are the other cameras...will the effect be sort like a white-out of the picture? Has anyone had this happen?

As long as the subject is far enough awayfrom the cams the pic or video you are taking will only get brighter and wont white-out.think of it like two cams being 1 with double the amount of IR's.
