@nayr can you get out your ruler and give me the diameter of the mounting holes in the base and the distance between centres? I've got both these and their 4mp brethren on the way but the specs don't have that detail. Have to order stainless steel security torx screws to mount them and don't want to order m6 if they wont fit. The 2mp will be the overview / driver cam and the 4mp will be the plate cam. I've also got external ir on the way. What shutter speed did you need to run to eliminate the flare on the plates? Also what diameter is the lens?
