Ikegami’s new wireless portable UHK-X700RF a robust camera
Ikegami has announced a new addition to its UNICAM-XE product range with the introduction of the UHK-X700RF wireless portable camera; it has the same feature set, operational ergonomics, compact size and light weight as its wired sister model UHK-X700.
Gisbert Hochguertel, Ikegami Europe Product Specialist, said, “UNICAM-XE series cameras are designed to allow fast and easy set-up, 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, outside broadcast (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.”
The UHK-X700RF is equipped with a native Ultra HD (UHD)-sensor (3840 x 2160 pixels) with a global shutter architecture designed to capture natural images even under challenging situations. The wireless camera supports UHD (2160@50p/59.94p) and HD (1080@50p/i, 59.94p/i) frame rates as a standard feature.
Like all other cameras within the UNICAM-XE family, the UHK-X700RF incorporates a dual filter wheel enabling separate control of incoming light and colour temperature. Space is included to mount any desired effect filter or an optical low-pass filter to further reduce aliasing and moiré artifacts.
The transmitter in the UHK-X700RF operates in the 2 to 2.7 GHz band, accessible in 250 kHz tuning steps, with an output power of 100 mW. Two antennas mounted at the rear of the camera 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 fast, typically just 40 ms input to output at UHD or HD resolution. Transmission range in a standard configuration is approximately 500 metres, and up to 22 transceivers can be used in a single system.
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.
In its basic configuration, the receiver/decoder can connect directly to eight down converters (four pairs of antennas) via conventional BNC cables; up to 100m cable extension can be supported.
