LAKE SUCCESS, N.Y., November 3, 2010 – Building on the success of its remote-control HD pan-tilt camera systems, Canon U.S.A., Inc., a leader in digital imaging, has introduced two new models 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 the exceptional HD video imagery, versatile performance, and non-proprietary control protocol of previous models while also adding new features that enhance their performance in locations where remote-control operation is essential.

“Television and video content creation of nearly every kind has transitioned to widescreen 16:9 aspect ratio HD,” observed 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. These applications include POV (point-of-view) cameras for traffic and weather monitoring, houses of worship, legislative chambers, and many other uses. Canon U.S.A. responded to these markets recently with its BU-45H and BU-50H outdoor and indoor remote-control HD pan-tilt camera systems. Now Canon is following-up on those very successful products with the new BU-46H and BU-51H, which provide additional features for even greater functionality.”

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 sophisticated Image Stabilizer technology.

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. The BU-46H is designed for exterior POV applications such as sports stadiums, horse-racing tracks, broadcast television “skycams,” and many others.

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 (NTSC or PAL*) 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.).
