Alongside the D7100, Nikon announced the WR-1 Transceiver, a unique wireless remote control. Able to remotely control multiple cameras capturing stills and videos, even time-lapse sequences, the Nikon WR-1 Transceiver mounts on the camera's hot shoe, yet is controlled via a cable attached to the master camera. Communicating with other remotes via its 2.4 GHz radio, the device can control other WR-1 units as well as other elements of Nikon's wireless remote control system, like the WR-10.

Mounted on the hot shoe, the WR-1 can lean forward 90 degrees, or stand upright for easier access to the controls and LCD. The WR-1 can be used as a transmitter or receiver, with a range of 394 feet. Overall range can be doubled by adding at least two additional WR-1 units, with the middle unit acting as a relay controller. The range of possibilities is extensive, including controlling cameras in up to four groups simultaneously, with each group performing different functions, including interval shooting, stills, bulb exposures beyond the usual limitation of 30 seconds, and even video capture.

Other options include staggered release using multiple WR-R10 units as receivers for multi-shot animations as seen in movies like The Matrix. With multiple WR-1 units you can even remotely adjust settings on other WR-1-equipped cameras, including ISO, shooting mode, shutter speed, and aperture.

Expected to retail for £649.99 in the UK, the WR-1 will ship in March 2013 (US pricing has yet to be announced).

Press Statement:

WR-1 Transceiver

In addition to the D7100, Nikon also announced the WR-1 Transceiver for Nikon D-SLR cameras. This device uses 2.4 GHz radio frequency for maximum range when communicating with the camera, extending the range and functionality2 for remote shooting applications. The communication range between WR-1 units is approximately 394 feet3, and 15 channels are available. Users also have the ability to remotely control a camera (with a WR-1 used as a receiver) attached by operation of another WR-1 (used as a transmitter), and also perform simultaneous or synchronized release of shutters on several cameras using the WR-14. Furthermore, there are a wide variety of options for remote shooting, which include dividing remote cameras into groups and controlling each group separately and interval timer photography. Remote shooting by combining the WR-1 with WR-R10/WRT10 wireless remotes is also possible5.

2 Functions limited.
3 Approximate range at height of about 1.2 m/4 ft; varies with weather conditions and presence or absence of obstacles.
4 Only a camera with a ten-pin remote terminal can be employed as a master camera.
5 This requires pairing of the WR-1, WR-R10 and WR-T10 units in use. Maximum number of controllers that can be paired: 20 (WR-1) or 64 (WR-R10)
