Question: Do you have to server to use this product (Go-pro Wifi Bac Pac AWIFI-001)
Document: The go pro wifi bacpac turns your gopro 2 into a go pro 3 well almost but its great. Use your smart phone or remote to control and view what your camera sees. Only down side is i forget to charge the wifi bacpac when i charge my camera, and camera doesn't charge the wifi.pro*EZ to use*Android and IOS*Must havecons*has its on battery
Got a Hero 2 for Christmas and this was a good deal so I picked it up. Updated the firmware on the camera and the Bac Pac before hooking it up and then the rest of the setup was easy. The picture you see in the app is delayed about 4 seconds, but it is still nice enough to use to position the camera.One very nice perk is that you can control ALL of the functions of the camera from the app when you have the Bac Pac attached!!!
Recd product defective,however Go pro sent me another under warranty but still unable to work. Questioning if these are refurbished makes? will followup with go pro.
spent hours online and with go pro online support, why sell a product you have to update online to get to work then if you get an on;ine glitch spend hours trying to fix and no solution available.I do computer programing as a hobby and have a lot of comp savvybut had nonsuccess. Item should work right out of the box.
This is a fantastic product, and I can't say anything poor about it. I will however tell you this. It fits my Go-Pro 2 Hero camera, however, it is not without issues. This device was developed as an afterthought to the Hero 2, and because of that the Hero 2 camera does not work with it. However, the Go-Pro customer service people will walk you through several firmware updates for your camera and this backpack to get them to talk to one another.
All is good except for a slight problem. Wished the wifi bac pac has an on off control remotely from the phone app too. The app can control the camera but not the wifi and the life of battery of the wifi bac pac is quite short and without the wifi, the unit is as good as dead even if the camera battery is full especially when the unit is fixed on a difficult to reach position. However hooking up the unit to a powerbank helped a lot :-) lasted almost 10 hours.
I have it running off my android phone and it is miles better than using that small menu on the go pro unit. I also love the live shot but it works but there is a small lag. will have to use it more but for now I see a useful unit that will help me in my time-lapse.
GoPro WiFi Bacpac AWIFI-001 is the way to make your GoPro truly useful. I highly recommend it. Money well spent.
I've been watching this item for awhile, I just never ordered. When I saw the price drop to 18.99, I immediately made the purchase. I think all Go Pro user have some frustration that they are unable to view what the camera. Using an GoPro app, I am able to view my camera's shot. The wifi range is okay. I placed my Go Pro w/ the wifi bacpac on my car's front bumper area.
It works very well with my Android phone. While I have my phone mounted on the stem of my bike is easy to control my go pro 2
Answer: I use this product with the wifi turned on my phone. The GoPro app allows you to use the camera and with the latest firmware update, you can view images and videos shot. When I am at home, I just take the card out and transfer my files to my computer.
