Hello,
I recently purchased a Swann pro-750 PTZ camera to work with my QT428 DVDR but I'm having trouble connecting the camera to the DVDR.
At the back of the DVDR I have 4 (ports) right under the RS485 mark.
P/Z
(Y)-(Z)
K/B
(A)-(B)
And the PTZ camera have a purple and grey cable.
The PTZ controls works with the Swann infrared controller and remote, but can't seem to make it work with the QT428 DVDR.
Thanks a bunch.
