That is in fact a Fire Department Connection (FDC) on the OP. They are used by the fire dept to supply water to the stand pipes (water hose outlets in a complex or building), a fire sprinkler system, (to augment or straight supply) or both stand pipes and sprinklers.
The little red pipe is a PIV - Post Indicator Valve (A simpler one pictue ). It is used to control the water to the system and show if the system is open or closed. That's is what is in the little glass window is for on the pipe. The little red box on the side with the black cable coming out of it is the tamper valve. If you shut down the system - say to burn the building down - it will will sound off at the alarm monitoring company.
I hope this helps
