Remotely operated camera head with three axes of rotation (pan/tilt/roll) for filming in inaccessible or hazardous locations. Payload capacity 15–150 kg with brushless servo motors.
Technical Details
Current remote heads carry payloads of 15-150 kg and feature brushless servo motors with encoder feedback. The Libra Head V, for example, carries up to 27 kg with a tare weight of 18 kg. The three axes of rotation offer movement ranges of 360° (Pan), ±180° (Tilt), and ±270° (Roll). High-quality models integrate gyro stabilization and can be synchronized with motion control systems. Power is supplied via 12-48V DC with power consumption between 50-200 watts.
History & Development
The first commercially successful remote head was developed in 1985 by Libra Head Systems, after camera technicians sought solutions for hazardous shooting locations. In 1992, Hot Head introduced blimp-free technology, which eliminated motor noise. The breakthrough came in 2001 with Technocrane's integration into crane systems. Since 2010, digital encoders and CAN bus communication have enabled programmable camera movements with millimeter accuracy.
Practical Use in Film
Remote heads allow for shots in inaccessible areas: explosion scenes, underwater housing setups, or extreme crane positions. In "Mad Max: Fury Road" (2015), Russian Arm-mounted remote heads were used for dynamic chase sequences. A typical workflow: the camera assistant monitors focus remotely, while a second operator controls the head movements. In studio shoots, they significantly reduce crew size and ambient noise on set.
Comparison & Alternatives
Unlike gimbals, remote heads operate with greater mechanical precision but are less mobile. Fluid heads offer direct tactile feedback, while remote heads can program repeatable movements. Motion control systems enhance remote heads with repeatability for VFX shots. Modern alternatives such as the Bolt Cinebot combine robotic arm technology with remote head precision for more complex motion sequences.
