The GoPro Hero line of “active” HD camcorders has been hugely popular about extreme enthusiasts, but there’s only so much you do with one camera. The newly announced Wi-Fi BacPac and Wi-Fi Remote take care of that.
They work in tandem with existing GoPro cameras, so you can go ahead and use all the different mounts for all sorts of interesting camera angles. Use the helmet cam, the chest cam, the handlebar cam… whatever tickles your fancy. Then, with the Wi-Fi BacPac and Wi-Fi Remote combo kit, you can then control multiple (up to 50!) GoPro cameras from your smartphone or tablet. You can also use the included waterproof Wi-Fi remote.
You get an ideal wireless range of 600 feet. While you can currently stream the video from the GoPro cameras to your smartphone or tablet, a future update will let you livestream that video onto the web. A multi-camera action-enthused livestream! GoPro’s wireless combo is available now for $99.99.[Source]
