Camcorders a generally designed for well lit scenes, using the light to create a quality color image for recording. To ensure that the image is seen by the camera in a similar way to our eyes, only the portion of the light spectrum that is visible to our eyes is processed.
Unfortunately, you cannot simply add an infrared illuminator to your camcorder and use it to capture night vision video because the CCD imager contains a glass filter that blocks out most of the infrared light.
Most video camcorders allow an external video source to be plugged in, essentially replacing the built in CCD imager with some other compatible video source. This video input will often have some custom manufactured input jack with a label of "external", "line input", or "AV input".
You will have to identify both the external video input and acquire the proper input cable in order to build this project, but if you kept all of the accessories from your camcorder, then that odd cable will probably be still sitting in the box, as it usually not used.
