PTZ Controller supports Sony VISCA protocol. It works with Sony cameras.
About Preset Position of PTZ Camera, PTZ Controller only supports what the camera supports.
Only 6 Preset Positions are supported by Sony’s camera. That’s why you can not save more than 6 Positions on your Sony camera, though PTZ Controller provides 127 presets.
You also need to turn on BACKUP switch on you camera to save the Preset Position when the power is turned off. Otherwise, all settings return to initial values when the power is turned on the next time.
