The Marshall VS-PTC-300 PTZ NDI Camera Controller is designed to operate seamlessly across multiple camera protocols on a single network. Used for live event production and content creation, the VS-PTC-300 offers detailed operation through a high-quality PTZ joystick, professional zoom rocker, and individual fine-tune adjustment knobs for iris, white balance, exposure, red/blue, shutter speed, focus, pan/tilt speed, and zoom speed. The VS-PTC-300 offers cross protocol mix-control on one controller operating RS232/RS422/RS485 and IP, as well as ONVIF, and VISCA over IP. The VS-PTC-300 can setup 7 cameras via RS232, 14 cameras via RS422, and 255 cameras via NDI/IP; all selectable through a single controller. Easy NDI/IP camera discovery function automatically searches for all available NDI/IP cameras on a network.
