Repairing the Sercomm RC8230 PTZ Camera

by @edent | # # # # # | Read ~300 times.

I've been busy writing the definitive Sercomm Camera API documentation. (No, you need a hobby!) While doing so, I noticed that I couldn't get my Pan/Tilt/Zoom camera to... well... pan! No lateral movement whatsoever. It'd move up and down - but its left and right movement was non-existant. I could hear the stepper motor whirring,… Continue reading →
