New Canon Pan/Tilt POV Cameras Offer 2X Extender, Night Mode

Canon U.S.A. has introduced two new remote pan/tilt cameras with additional features to serve a wide range of broadcast and professional users. Canon’s new BU-46H outdoor and BU-51H indoor remote-control cameras deliver HD video imagery and non-proprietary control protocol of previous models while also adding new features that enhance their performance, according to the company.
“Television and video content creation of nearly every kind has transitioned to widescreen 16:9 aspect ratio HD,” says Larry Thorpe, national marketing executive, Broadcast and Communications division, Canon U.S.A. “Specialized applications requiring versatile and cost-effective remote-controlled HD pan-tilt cameras are no exception.”
Canon’s new BU-46H and BU-51H remote-control HD cameras include a new 2X digital extender to double the image size of distant objects captured with the cameras’ 20X Canon HD zoom lens (4.5 – 90mm). Both cameras are equipped with three 1/3-inch (1.67 million-pixel) CCD sensors (1440 H x 1080 V) and also feature an advanced Canon Auto Focus function and Canon’s Image Stabilizer technology.
The BU-46H is designed for exterior POV applications such as sports stadiums, horse-racing tracks, broadcast television “skycams,” and many others.
The imaging capabilities of the new BU-46H and BU-51H remote-control cameras are further enhanced with the inclusion of a newly designed Night Mode feature. This new feature works by slowing down the shutter speed to a minimum of 1/4 (60i, 30F) or 1/3 (50i, 25F, 24F) allowing frame accumulation that elevates camera sensitivity.
A new feature of Canon’s new BU-51H indoor remote-control camera is a built-in microphone with adjustable settings. Designed for such environments where quiet operation is essential – including recital halls, lecture rooms, and auditoriums – the BU-51H features a maximum noise level of NC30. The BU-51H is also equipped with pan/tilt/zoom focus position information output for integration with virtual-studio systems and other specialized applications.
The BU-46H outdoor remote-control camera features a weatherproof housing that meets the IP-45 specifications for dust- and waterproof-efficiency. The camera also features a remote-control ND (neutral density) filter; its housing includes a “windshield-wiper” type blade to keep its lens port clear. The BU-46H can pan through ± 340 degrees and tilt + 30 degrees ~ -50 degrees in highly precise and smoothly choreographed movements specifically designed to address multiple applications.
Both the BU-46H and BU-51H cameras feature a non-proprietary control protocol that enables users and system integrators to interface the camera with their own control system or that of third-party providers to create a versatile remote-control system. Both cameras can be operated in automatic or manual mode and can pan, tilt, and zoom simultaneously to up to 32 preset coordinates.
Both the BU-46H and BU-51H remote-control cameras provide genlock input for broadcast video-system synchronization. Video outputs include HD-SDI with embedded audio for HD recording and a simultaneous analog composite output for monitoring. Short- and long-distance control systems interface via RS-422 connections. An optional third-party E/O (electrical-to-optical) converter is available to enable worldwide connectivity via fiber optics or a connection to the Canon Canobeam DT-150 HD wireless video transceiver for transmission at distances of up to one kilometer.
The total weight of the BU-46H is 17 kg. (approx. 37 lbs.); the total weight of the BU-51H is 11 kg. (approx. 24 lbs.).
