The Wi-Fi BacPac is compatible with both the HD HERO Original and the HD HERO2 camera. It is not compatible with the HD HERO 960 camera.
The remote function of the Wi-Fi BacPac is compatible with the HD HERO Original camera. This allows you to remotely power the camera on/off, and start/stop recording.
The smartphone application is not able to sync to the HD HERO Original camera, so live preview and mobile device functionality is not possible with this camera model. This feature is available with the HD HERO 2 camera. HERO 3 and HERO3+ cameras have Wi-Fi built in and do not require a BacPac.
