Canon Advances Remote-control HD Pan-Tilt-Zoom Cameras With BU-46H And BU-51H

Building on the success of its remote-control HD pan-tilt camera systems, Canon 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 of previous models while also adding new features that enhance their performance in situations where remote control operation is essential.
The cameras include a new 2X digital extender to double the image size of distant objects captured with the camera's 20x Canon HD zoom lens (4.5mm-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 Stabiliser technology.
The imaging capabilities of the new BU-51H remote-control cameras are further enhanced with a newly designed Night Mode feature. This 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 environments where quiet operation is essential - including recital halls, lecture rooms and auditoria - 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 systems and other specialised 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 neutral density filter, while the housing includes a 'windscreen 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 for multiple applications. The BU-46H is designed for exterior POV applications such as sports stadia, horse-racing tracks, broadcast television skycams and many others.
Both the BU-46H and BU-51H cameras feature a non-proprietary control option that enables users and system integrators to link the camera with their own control system or that of third-party providers to create a completely versatile remote control solution. Both cameras can be operated in automatic or manual mode and can pan, tilt and zoom simultaneously to up to 32 pre-set coordinates.
Both the BU-46H and BU-51H remote-control cameras provide genlock input for broadcast video system synchronisation. Video outputs include HD-SDI with embedded audio for HD recording and a simultaneous analogue composite output NTSC or PAL for monitoring. Short and long-distance control systems interface via RS-422 connections. An optional third-party electrical-to-optical converter is also available to enable worldwide connectivity via fibre optics or a connection to the Canon Canobeam DT-150 HD wireless video transceiver for transmission at distances of up to one kilometre. The total weight of the BU-46H is 17 kg (approx: 37 lbw); the total weight of the BU-51H is 11 kg (approx: 24 lbw).
