1. RE-USE THE CAM First it had to have USB added to take videos off. I prefer to do this by sticking a male connector right out of the side of the camera instead of a port.
2. MAKE IT INFRARED Then the infrared filter was removed. I found instructions somewhere on the camerahacks forum for doing this; it’s extremely easy. You unscrew the lens on the ccd and use a knife blade to pry the infrared filter out, then screw the main lens back on (to the exact same spot it was at originally to maintain focus). Now the camera can see in infrared light (and visible light, but with night vision you want anything you can get). All you need to be night vision is an illuminator. This is wicked easy to do with IR LED’s.
this is a simplified version of what the author writes about this project, as you can see there are 2 main aspects of this project.
