With respect to the camera glasses:
These have very limited acceptance for video shops work. Shoppers have to be able to turn their heads to look at things being pointed out by the target, while still keeping the target in the picture frame. For that, the body-mounted camera is a MUST. Also, clients and editors report getting vertigo from the sharp changes in ascpect that come with the eye glass cams.
They are a last resort for capturing targets during a bank drive thru, for instance, or when the target is behind a very high counter (car rental scenarios). If/when they are needed, the MSCs usually will loan you a set. AND, they are of very, very limited use for those of us who actually need glasses to see to do the shop!
In other words, you will miss very little by not buying your own video cam glasses.
