I am really, really enjoying my GoPro video camera. For $200 to $300 you can get a great 1080p video camera that you can put almost anywhere. It will also take time lapse images which [I've been really enjoying lately][youtu]. At CES this year GoPro announced a really sweet accessory for their cameras.
The Wi-Fi BacPac + Wi-Fi Remote connects your GoPro camera to your iPhone, iPad or iPod Touch through a Wi-Fi network it creates. Once connected, you can see the live video output of the camera as well as control what it's doing.
It will also connect up to 50 GoPros at a time, giving you the ability to put these small cameras all over a shooting area and control them remotely.
Controlling 50 cameras might not be the use-case of the average person, but putting the camera in a hard to reach place and then controlling it with your iPhone opens up all kinds of possibilities creatively. Imagine putting the camera on your kid's skateboard helmet and then watching what he's doing live from his point of view. Or imagine attaching the camera to the hood of your car and turning it on periodically during long road trips. There is huge potential for cool things to do with it.
The WiFi BacPac will be available March of 2012 for around $100. It will work with the new HD Hero 2 cameras, as well as the HD Hero with limited capabilities (you can control the camera but you won't get live video streaming with the HD Hero).
