We have installed three analog cameras that are going to monitor the signal-recycling mirrors (i.e. SR2, SR3 and SRM) on HAM4 and HAM5. We put a good TV lens on each of them and adjusted the aperture and focus.
The detailed location of the cameras are described in the viewport final design document (page 54 and 55 in DCC-T1000746-v7) and we followed it.
