First CGO ET Camera I received was broken right out of the box, bent gimbal. Returned it and received a replacement last week. Installed it on the H520 today, ST16S see's it, asks for a password, I put in the "1234567890", and the ST16S says "Invalid Password". I've repeated 10 times with the same result. Anyone have an idea on how to fix this? Is there a "Master Password" that the Tech's use to get around a forgotten password? Oh, I have no problem with my E90 camera.
