These advanced cameras come equipped with patented laser-hit detection software that enables sub-pixel accuracy when determining shot location in the virtual world of the simulation being projected. These cameras are commonly integrated into the projector to ensure constant alignment and maximum portability. Integration of the laser-hit detection camera is one of the primary features that make SIMrange simulators industry leaders in setup time and ease-of-use. Non-integrated cameras setups are also available and may be preferable if you already own a projector or if portability is not a primary concern.
