Bowcam (2D)
Click Image to Enlarge
The BowCam is a point to point camera system which uses cables to carry a camera platform (Dolly) between two mounting points.
The unique design of the BowCam allows it to change altitude at any given moment. Each of the two winches hold two high-tensile Aramid cables. By winding/un-winding these cables, direction, altitude and speed of the dolly are controlled.
Joysticks are used to input the commands, which are then transmitted via glass fiber cables, guaranteeing an interference-free transmission without the need for radio transmission.
In defiance of its compact size the dolly is gyro-stabilized in all axis offering unbelievable stability even at speeds of up to 9.5 meters per second.
