The camera positioning apparatus according to claim 7, wherein a camera is secured to said gimbal bracket assembly. 14. A camera positioning apparatus comprising: (a) a mounting bracket; (b) a gimbal bracket assembly having three orthogonal axes, wherein said first axis is roll, said second axis is yaw and said third axis is pitch and wherein said gimbal bracket assembly is secured to said mounting bracket; and (c) a plurality of locking mechanisms, each of said locking mechanisms operative to lock said gimbal bracket assembly about a respective one of said three orthogonal axes, wherein said locking mechanism operative to lock said gimbal bracket assembly about said first axis is on said first axis; and wherein said locking mechanism operative to lock said gimbal bracket assembly about said third axis is on said third axis. 15. The camera positioning apparatus according to claim 14, wherein said gimbal bracket assembly comprises: (a) a ring bracket, rotationally secured to said mounting bracket and operative to rotate about the first axis; (b) a square bracket, pivotally secured to said ring bracket and operative to pivot about the second axis; and (c) a carrier bracket, pivotally secured to said square bracket and operative to pivot about the third axis. 16. The camera positioning apparatus according to claim 15, wherein a first of said locking mechanisms locks said carrier bracket relative to said gimbal bracket assembly and a second of said locking mechanisms locks said square bracket relative to said gimbal bracket assembly. 17. The camera positioning apparatus according to claim 16, wherein said first and second locking mechanisms include interleaving of ridges on adjacent bracket surfaces. 18. The camera positioning apparatus according to claim 15, wherein said mounting bracket includes a plurality of clips to removably and rotationally secure said ring bracket to said mounting bracket. 19. The camera positioning apparatus according to claim 15, wherein said ring bracket is locked relative to said mounting bracket by a screw. 20. The camera positioning apparatus according to claim 14, wherein a camera is secured to said gimbal bracket assembly.
