TLDR. Super light. Pretty good video, easy configuration, can be hard to use.
I was asked to review the Mobius ActionCam since I was getting a GoPro Hero 3 around the same time. It was handed to me in a plastic bag with no packaging or software. I'll save you some time,http://www.mytempfiles.info/mobius/index.html is where both the config software and a .pdf of the manual are. Looks like the config software is only available for windows. You can also print the manual from within the config tool. Read on for the full Mobius ActionCam Review.
I would recommend at least taking a look at the manual. You can run the config software without a camera attached so you can take a look at the options before you buy. Actually, I'll save you some time. Here are the two main screens of the config software.
My camera came with the v0.34 firmware. I repeatedly tried using the app to upgrade to both v0.39 and v0.41 with no success.
1080P HD Video Quality
The Mobius can record in gorgeous 1080P H.264. HD video quality at 30 frames per second. At the highest video quality, the bit rate will be nearly 18,000 kpbs in wide angle recording. There is also a 720P 60 frames per second option suitable for extremely fast action recording, and WDR (Wide Dynamic Range) recording for low light scenarios. A Time Lapse mode, where the camera will automatically take Time-Lapsed still images is also included.
The Mobius can record for approximately 80 minutes at a time. Add a power bank (not included) to increase the battery life. The Mobius is capable of recording live video while plugged in as well.
The Mobius records audio with 3 volume settings at 512 Kbps PCM (CD quality).
Use it as a Car Camera
With the car mount and car adaptor (not included), the Mobius makes an effective dash cam. As soon as the Mobius is plugged into the car power adaptor it will start / stop record based on driving, no need to press record. With the Mobius’ video quality and wide angle view, you can read any license plate on the road with ease.
Mounts and Accessories
Included with the Mobius is an attachment sleeve, a Velcro mount and a USB cable. Optional accessories include: bike handlebar mount, car mount, mini tripod, car adaptor, and helmet mount & waterproof case (coming soon!).
A couple of interesting things; The Amazon listing says that it weighs "only 1 pound". It weighs only 1.7 ounces in its holder. You'll never even notice the weight. Most likely any RC vehicle you put it on won't really notice it either. In this respect it's much better than my GoPro Hero 3. (The GoPro Hero 3 needs the plastic case in order to have a mount. Out of the box that'll weigh 6.5 ounces and be a lot bigger.) Also, the Mobius ActionCam description says microSD card up to 32G. The software didn't want to format the used 64G card that I had lying around but when I dropped a new 64G microSD card in I had no problem formatting and using that.
The Mobius ActionCam is sold by a company called Spy Tec. I think that unless you're mounting on a small RC vehicle or on a helmet and you don't want to look like a teletubby (like a GoPro user) that the spy features are what make it compelling. You can set it so that there is no recording indicator and so that it will start recording when you turn it on. You can even set it so that there is a slight delay between when you turn it on and when it starts recording. This would let you get out of the picture in time to not be in the video. However, the same things that make it good for "spy" purposes are what make it something that I'm not likely to use. I found it pretty hard to use in more than just a "turn it on and forget it for an hour" way. You have to use the LED color and blink combinations to figure out what mode it's in. I ended up needing to keep a hard copy of the manual handy. You can find a number of videos on YouTube but since YouTube recompresses video that won't tell you what you'll get at home. However, if you're going to upload to YouTube anyway then go look at the videos to see what quality to expect.
