Control up to 255 IP PTZ cameras with the PTZ Camera IP/NDI Controller from Marshall Electronics. This controller is designed to operate across multiple camera protocols on a single network, including via IP, NDI, USB, and RS-232/422/485 serial protocols. The controller is equipped with a precise joystick for one-handed PTZ control, an alphanumeric keypad, a tactile zoom rocker, an iris knob, and an LCD screen for navigating keyboard settings. You can control up to seven cameras via RS-232, up to 14 cameras via RS-422 (via daisy chaining), and up to 255 cameras via IP/NDI. You can also auto-discover NDI cameras on a supported NDI network.
