  U3 4K
Remote Head

The U3_4K is a small pan and tilt head developed specifically for the new ALCM 460 4K camera and has both a camera power supply, lens control, and CCU protocols built in.

Connections to the unit are twin ST fibre plus power or BRADLEY standard RS485 data. One fibre is dedicated to returning the quad 3G pictures and the other is for control data and genlock to the camera and head. using fibre connections enables ranges of up to 20km. All the fibre interfaces are built-in with matching connectors for direct connection to teh ALCM 460 camera.

The U3_4K is extremely quiet, smooth, fully featured for both live action moves and preset positions together with full camera and lens control using BRADLEY standard protocols. The head is weatherproof and can be used externally without further protection. A slip ringed option is also available for continous 360 degree pans.

Fully proportional joystick control enables moves from 90 degrees/sec to 0.02 degrees/sec or less. This gives smooth moves even with long lenses. The preset positions are achieved quickly and with accuracy of better than 0.5degrees.

A matching Base Station is available for returning the quad 3G pictures and multiplexing control data with genlock up to the camera. SMPTE hybrid cable versions are also available, making 4K migration as simple as possible.

A number of joystick controllers are available from BR Remote, along with various RCP options for camera CCU control. Up to 99 cameras can be controlled on a single system.
