Camera Losing Sight Close Up

[ebowla]

Well, so far we have been able to get the camera to work properly to a point. It tracks the light perfectly, and when it loses sight of it it does its search pattern to find the light again. Heres where the problem comes in. When we move it close enough to the light (which is at the height it will be at the competition) it starts acting odd. It will find the light for a moment, then instantly lose it and refind it, without doing its normal search pattern. It repeats this constantly until we move it further back. I made sure that it could see the light at all times, nothing was blocking it. I also checked the max tilt value and it is far enough back that it would allow for it to go directly under the light if need be. Any ideas of why this pattern of locking on and losing sight over and over when close to the light is happening, but not when the camera is further away?
