The company behind the GoPro wearable HD video camera has released its much-anticipated Wi-Fi BacPac + Wi-Fi Remote Combo Kit, allowing people to control multiple GoPro cameras at a time using either a smartphone, tablet, or the included waterproof Wi-Fi Remote.

The Kit will offer live streaming video from GoPro cameras to smartphones, tablets and directly to the web via a software update that's due 'soon'. Additionally, a free, soon-to-be-released GoPro App will enable GoPro cameras to live video stream to – as well as be controlled by – iOS and Android smartphones and tablets.

The Wi-Fi BacPac attaches to the back of GoPro cameras.  The waterproof and wearable Wi-Fi Remote can control up to 50 GoPro cameras at once from a range of 600 feet (180m).

To promote the launch, GoPro gave a Wi-Fi BacPac + Wi-Fi Remote Combo Kit to skateboarder Ryan Sheckler so he could skate an area of New York City that he’d always dreamt about and document his experience using 50 GoPro cameras positioned along his path.

The resulting short film, New York City, documents a “day-in-the-life” skate from the top of the Manhattan Bridge through Chinatown, finishing at the entrance to the storied Lower East Side skate park. the film was shot entirely on GoPro cameras.

The Wi-Fi BacPac + Wi-Fi Remote Combo Kit costs $99.99 (around £65).
