mimilovell 0 Posted February 25, 2014 To control a PTZ camera, I find it easier to connect a ptz controller ( like thenone shown below) rather than using the DVR remote control. http://www.tradexguru.com/3-axis-black-joystick-cctv-ptz-controller-rs485-bus-with-blue-lcd-screen.html Share this post Link to post Share on other sites
