Will IR Illuminator work with any CCD Camera?

[wdoe999@xxxxxxxxx]

I want to setup some night surveillance cameras.  I notice that some
CCD night cameras have the IR LEDS right on the camera.  Do these
cameras have anything special about them that makes them work well with
IR illumination (do they have circuitry to switch to B/W etc).  The
reason I ask is that I would prefer to use standard CCD cameras and a
separate IR illuminator, and am wondering if they will work together
properly.  Thanks.
