Is their any length limits on the composit cable you can use ? I am running a Speco CVC-6705 bullet cam which has a 1.0 Vp-p 75 ohm composite output. I see they make a 150' which would be long enough for my application, I just did not know if I would lose any quality. Thanks for any advice on this.

If there is no extrenal interference (eg b/c the cable is running along other cables with high Amps) RG59 cable will easily take you to 300 ft (even to 750ft). Make sure you have 75Ohm termination at both ends. Only other thing to consider is possible ground loop, which would typically result in horizontal banding and can be resolved by use of a ground loop isolator.
