PTZ Camera Keyboard Controller Clear control and reliable communication for PTZ surveillance systems. This compact keyboard provides precise three dimensional joystick control, a readable LCD, and long distance RS485 connection for professional monitoring environments. Key benefits Precise, intuitive control: Three dimensional joystick moves the PTZ up, down, left, and right, and twisting the joystick provides smooth zoom control for fast target acquisition. Long range communication: RS485 bus interface supports communication up to approximately 1500 m / 4921 ft using 0.5 mm twisted pair cable, enabling centralized control across large installations. Broad compatibility: Compatible with Linux systems and most dome and network cameras. Supports common PTZ protocols for easy integration into existing surveillance setups. Flexible configuration: Selectable baud rates and standard communication parameters ensure interoperability with a wide range of PTZ devices. Low power, compact operation: Operates from DC 12V 500 mA with power consumption under 5 W, making it practical for control stations with constrained power budgets. Ready to use: Simple out of the box setup for immediate deployment. Main functions and performance Joystick: Three dimensional control for pan, tilt and zoom; twist action controls optical zoom for smooth operator input. Display: Built in LCD provides status and menu navigation for setup and operation. Communication interface: RS485 bus for reliable serial control in industrial and security networks. Communication distance: Approx. 1500 m / 4921 ft with 0.5 mm twisted pair cable. Communication protocols: PELCOD, PELCOP, and AD compatibility for standard PTZ devices. Baud rates supported: 1200, 2400, 4800, 9600, 19200. Communication parameters: 8 data bits, 1 stop bit, no parity. Electrical Input voltage: DC 12V 500 mA Power consumption: Less than 5 W Package contents 1 PTZ Camera Keyboard 1 Power Plug 1 User Manual Typical use scenarios Urban or city surveillance control room: Centralized operators manage multiple dome cameras across long cabling distances using RS485 links and selectable protocols. Financial or government facilities: Precise pan, tilt, and zoom control for bank counters, secure entrances, or courtroom surveillance where reliable, low latency control is required. Campus or transportation monitoring: Control point for parking lots, transit hubs, and campus perimeters where compatibility with a variety of dome cameras simplifies system integration. Technical notes Designed for use with PTZ dome and network cameras that support RS485 control and the listed protocols. Use 0.5 mm twisted pair cable to achieve the specified communication distance. Default communication parameters are 8 data bits, 1 stop bit, no parity; verify device settings when integrating with other equipment. This PTZ Camera Keyboard Controller delivers straightforward operation, stable long distance communication, and protocol flexibility for professional surveillance installations.
