The BacPac module adds a bit of bulk to the GoPro camera and won't fit into the stock waterproof housing, so GoPro includes two replacement rear doors with the kit. One door is completely sealed to retain the case's waterproof rating -- it even includes a waterproof button pass-through so you can still access the BacPac's Power/Menu button. The other door is ventilated for use in dry conditions where you may want slightly better audio recording quality. The ventilated door exposes the USB charging port and the Power/Menu button.
The Wi-Fi remote is the part of this combo kit that the user actually interacts with. This little black plastic module measures about 2.5 inches wide by 1.4 inches tall by 0.75 inch deep and connects wirelessly to the Wi-Fi BacPac to assume control of the connected GoPro camera.
The face of the unit features two rubber buttons that mirror the functions of the GoPro camera's Shutter and Mode/Power buttons. So once connected to the BacPac, I was able to power the camera on and off, choose between its various shooting modes, head into the camera's menu to adjust the various settings of those modes, and start and stop recording video or capturing still photos. I noticed while digging through the menus that there's a new Bluetooth On/Off option that, when selected, displays a "Coming soon from GoPro" message. This new option may come in handy with the upcoming GoPro App for Smartphones and Tablets, which we'll come back to a bit later in this review.
Next to those rubber buttons is a monochrome LCD that is identical to the one on the front of the GoPro camera and mirrors the data displayed there. So I was able to view the shooting mode, monitor the battery level of the camera, observe the amount of available storage space, and view the menus for changing the aforementioned options.
The Wi-Fi remote's sealed construction makes it waterproof down to 10 feet of submersion. A pair of slots on the back of the device accommodate an included wrist strap, making the device wearable. Users can also dangle the remote from a key-ring-like attachment ring located at one end of the device.
That attachment ring can be removed with a flick of a release switch located on the unit's back and a tug. In its place, a proprietary charging cable can be attached and plugged into any powered USB port to recharge the remote's internal battery. At this point, the GoPro user has three devices to remember to charge between sessions (the BacPac, the remote, and, of course, the camera itself), which verges on ridiculous, but I think the extra functionality is totally worth it.
The Wi-Fi combo kit retails for $99.99 and includes everything that you need to fully convert one GoPro HD Hero or HD Hero2 camera for fully wireless operation. That's not a bad price to pay to boost the functionality of one of the best sports cameras on the market and it opens up a world of creatively mounting the rugged HD camera in previously inconvenient places. (Imagine stuffing one of these cameras in your car's wheel well to watch the suspension components work under load!) However, GoPro still has a few extra tricks up its sleeve for the Wi-Fi BacPac and remote.
Additional Wi-Fi BacPacs can be purchased at $59.99 a pop, enabling a single Wi-Fi remote to control up to 50 GoPro cameras at a time (as long as they all remain in its approximately 600-foot maximum range). Eventually, GoPro says it will even release a GoPro App for Smartphones and Tablets that will allow your mobile device to do everything that that Wi-Fi remote can do and then some -- including adding the option to preview and play back media saved on one or more GoPro cameras and to live-stream video to the Web using a smartphone's data connection. We'll update this review to reflect those changes when the app is released.
