Nikon WR-1 Wireless Remote Control Transceiver
The WR-1 Wireless Remote Control Transceiver from Nikon provides remote shooting applications for Nikon DSLR cameras. It can be used as a simple remote control to avoid camera shake when shooting or as a more sophisticated communication device between multiple cameras. This device uses the 2.4 GHz radio frequency for an extended range of 394′ (120 m) when communicating with a WR-1 enabled camera, and by using multiple WR-1’s as a relay, the range can be extended even further.
