Commercial The Comatra commercial systems are in a class of their own. Designed from the ground up to ensure a lifespan that is up to 5 times longer than other systems. A favorite with our customers is the CMT5600HD monitor. The CMT5600HD combines one of the best digital displays used in a rearview monitor together with a ALU body that is water-dust-vibration and shock proof.
