I have the same problem with my boyo camera. I just ordered some LED lights for the license plate lamps - i'll see if they produce less glare. If not, I guess you can tint the lenses to help some.
yeah i was thinking about doing this, My crimestopper has LED's on it for night vision and it really had great picture quality when i had taped off the bulbs for my license plate. I've tried different angles and nothing helps. Guess i'll give this a try and if it doesnt work i'll try tinting the bulbs to let out less light.Try fabbing a small plastic shield that fits around the camera housing and only protrudes a 1/4" or so. That might shield the cam from direct light from the plates bulbs enough.
I'm about to do a complete infrared illuminator setup for the front and rear of my T. IR illumination helps low light visibility for the cams, and gives me B&W video while in complete darkness.
