Polecam to debut GoalCam, StadiumCam at NAB Show

At the 2011 NAB Show, Polecam will introduce its GoalCam and StadiumCam stadium-sports OB system.

The package is a three-component system consisting of two GoalCam cameras and a StadiumCam with an extremely wide viewing angle. The GoalCam/StadiumCam system provides high image quality, true portability, fast installation and easy operation.

Once set in position, each camera can be left to supply video for the entire duration of a game. The system is a logical complement to standard Polecam rigs as well as the long-range zoom cameras traditionally used to get close to the action.

Each GoalCam and StadiumCam incorporates a 1/3in CMOS HD-SDI imager allowing the use of ultra-wide-angle lenses with high corner resolution. Both GoalCams are fitted with 125-degree low-distortion lenses that provide images of the entire goal mouth without visible barrel distortion. An adjustable bracket equipped with a weather housing allows the GoalCam to restabilize quickly if struck by a ball. Suspended from a single point, the mount will flex if a player collides with it. The 125-degree lens allows the entire goal mouth to be seen even when the output video is cropped from 16:9 to 4:3. This gives commentators the ability to report accurately that a ball has indeed crossed the line.

StadiumCam is equipped with a 170-degree fisheye lens that captures the entire stadium in a single view. Like the GoalCams, StadiumCam can deliver 1080i resolution at 50/59.94Hz. An optional downconverter is available to provide SD-SDI output where required.

All three cameras, plus two auxiliary cameras, can be operated via a single Polecam RCP remote-control panel. Integral data receivers allow full control of camera functions, including motorized iris adjustment. The data signal can be sent along standard audio cable, over optical fiber or via a radio link, and control data can be embedded into, or extracted from, an HD-SDI stream.

WMUR-TV Says FAA Drone Rules Preclude ENG
The FAA’s current rules and proposed ban on flight over people, requirement of visual line of sight and restriction on nighttime flying, effectively prohibit broadcasters from using UAS for newsgathering. ~ WMUR-TV General Manager Jeff Bartlett
