chopperdr,
SX16 is on nose-mount, ie forward of the panel where some aircraft have the landing light fitted (ours is moved to the skid crosstube, by the dead-weight PA speakers...). Field of travel limited to just 180 degrees in azimuth, pilot has no controller on the collective - not good.
The camera is the Wescam kit mentioned in the original Eurocopter book - I'm not at work so cannot provide the part number, but it's not the modern (MX15?) turret. Be warned that the weights and arms given for this kit in Sect 6 of the FLM are completely wrong. We wouldn't have been able to fly at all if the book figures (from memory, 207kgs for the entire system) had been correct. However, after reweighing and then getting the figures checked by a Eurocopter engineer we found that the system actually weighed 90.7 kgs. Big difference. However, the customers bought the old-fashioned console (CRT screen, processor, VHS(!) recorder all on a mount IN FRONT OF the rear seats). That's what throws our CofG way forward - make sure you shove all that stuff in the boot where it belongs and get an LCD instead of the heavy tube.
You'd get better info on how the kit should be fitted either from Bond in the UK or the BGS in Germany, who both put the nightsun on the left skid-front mount.
