Ikegami has unveiled its UHK-X700RF wireless TV camera.
Featuring a native UHD-sensor (3840 x 2160 pixels) with a global shutter architecture, the UHK-X700RF wireless portable camera is the latest addition to the company’s UNICAM-XE product suite. Designed to enable the capture of natural images in a range of conditions, the camera has the same operational ergonomics, feature set, and compact size as its UHK-X700 wired sister product.
UHD (2160@50p/59.94p) and HD (1080@50p/i, 59.94p/i) frame rates are supported as standard and as with all other cameras in the UNICAM-XE family, a dual filter wheel is incorporated, enabling separate control of incoming light and colour temperature. Any desired optical or low-pass filter can be mounted, further reducing aliasing and moiré artifacts. Automatic optical vignetting correction is supported when using OVC-compatible B4 bayonet mount zoom lenses, said the company.
Operating in the 2 to 2.7 GHz band, the transmitter is accessible in 250 kHz tuning steps, with an output power of 100 mW. Two rear-mounted antennas comprise one for the main video signal plus a smaller one for telemetry data. Multichannel antenna diversity is a standard feature, providing robust signal delivery in a wide range of transmission environments.
Encoding is typically 40 ms input to output at UHD or HD resolution and in standard configuration, transmission range is around 500 metres, said Ikegami.
The receiver/decoder for the main video signal occupies a 19 inch half-rack width chassis. It employs DVB-T modulation in QPSK, 16QAM and 64QAM. Bandwidth is switchable between 8 MHz, 7 MHz, 6 MHz and 5 MHz.
The DVB-T guard interval can be switched in four discrete steps: 1/32, 1/16, 1/8, 1/4, aiming to ensure robust signal quality, even in critical conditions. Forward error correction is also flexibly selectable from 1/2, 3/4, 5/6, 7/8 and 2/3 as a default value. H.265-HEVC, H.264-AVC and MPEG-2 video coding are selectable via the control menu. Almost all conventional broadcast frame rates for HD and UHD are supported in ITU-R BT.709 SDR and ITU-R BT.2100 HDR as well as BT.2020 wide colour gamut. The receiver/decoder comes equipped with four SDI outputs and supports 1.5G, 3G and 12G SDI formats including embedded audio. It also features two XLR three-pin analogue audio outputs, a BNC genlock input and a four-pin XLR 12 volt DC power input.
Gisbert Hochguertel, Ikegami Europe product specialist, said, “UNICAM-XE series cameras are designed to allow fast and easy setup, versatile operation and secure delivery of broadcast quality video. They share the robust build quality and intuitive control structure that have made Ikegami UNICAM camera systems a popular choice among television control producers in Europe and around the world. The UHK-X700RF opens a wide vista of creative perspectives for applications such as news, OB sports and coverage of stage events. Even in fully rehearsed studio projects, it offers producers the freedom to introduce unusual-angle shots at short notice.”
