There is not such thing as "stable firmware that recovers PTZ fault", so please no need to make excuses, just do not advice people to upgrade firmwares
Now you need to get the custom firmware for this board, that has PTZ enabled.
Great advice - upgrade firmware on a custom-hacked camera and guaranteedly lose PTZ :) That's what he has done already, because there's no PTZ firmware with that release date
What do you mean?
if it has simple light board, then all leds turn on at same time. If board has PWM input, then maybe it's dual light board? 4 IR + 4 white leds.
P.S. Alright, i see now what you mean, send me a private message with MAC and SN
