Hi my name is Paolo, I'm an electronic engr. I've been happily using a Vivotek 6122 camera quite for some time, the camera still works fine regarding the video and network section, but the PTZ section developped a fault. That is at power up it initialisizes very sluggshily the PTZ touring but just just in a cople of seconds it stops! Then no matter if PTZ commands are sent via network or via infrared remote control, it simply doesn't respond at all! Since I'm very familiar with repair works I would like to fix the camera myself but would need a schematic diagram or else some hint on the parts to be replaced. Thanks so much for any help you can give me.Paolo Cauli
