The PTZoptics camera line has 12 different selectable resolutions. These are changeable using the rotary dial on the back of the camera. Remember, each time you make a change to the rotary dial, be sure to power cycle your camera for the change to take effect. Here are the 8 different resolutions available on the PTZoptics camera line. The 576i and 480p resolutions are limited to only come out of the CVBS port on the camera, so they do not work using HDMI, USB, or SDI.
