It appears to be a set of 3-6 cameras, lights, a small flat-faced square emitter, cabling, and a small metal storage box. They are set up on either side of the road so that you must drive thorough them.
I would like more information regarding this contraption.
Is there any possibility that you can take a picture the next time you go through it?
Plan B is: Can you post the approximate location? Is there a town nearby or a milemarker for the checkpoint? If the satellite imagery on Google Earth or commercial imagery web sites are current, I might be able to find it and do some "Imagery Analyst" work (wow -- what a nostalgia trip! Maybe I'll have to use a light table!)
