Okay for What You Pay
on July 30, 2013
I purchased these to see if I could find a better way of documenting processes that were somewhat complex and that were not done frequently. Of course, you can always write stuff down, or record audio and video with a hand-held camera. Writing is too hard for me and too often you cannot go back later and understand what you wrote. An audio/video recording would be okay except that you only have one hand free since you have to, in general, hold the camera.
So, a solution might be to use glasses like these to record audio/video without having to actually hold the camera. Surprisingly, when I started looking at these, there seem to be quite a selection of products and widely varying prices. I decided to not buy the cheapest and bought these glasses based upon mostly "good" reviews and the price was okay for "testing".
I thought the quality was quite good. As noted by a previous reviewer, the instructions are just about useless, but, you can figure out most everything through trial and error. I inserted a micro SD card that I had laying around and connected the glasses to my laptop. They were automatically recognized as a computer "drive" as expected. There were several file folders in the drive, but, since I didn't know what they were, I tried to re-format the SD card. I got an error message from Windows 8 saying "reformatting had failed".
So, now what? Are the glasses or the car bad? I decided to try the glasses as is. They took photographs and played music ok. I did not do an extensive test of the music playback since I was really only interested in the camera. Next, I walked around outside for about 20 minutes. When I got back and hooked the glasses back up to the laptop, the SD card showed that data had been stored. So, it is probably unnecessary to format the card because the glasses does this automatically.
Playing back my video started out well. But, after only about 2 minutes into the 29 minute video, the video stopped playing even though the "slide" bar on the bottom of the media player indicated that there was much more data. So, I recorded another, shorter, outdoor video. Playback results were the same - the video would stop playing about a minute or so after starting. The stop time looked purely random.
I decided to purchase another micro SD card since I didn't really know anything about the one I was using. SD cards are rated by "classes", up to 10. The higher the class number, the faster the card. I ordered a Class 4 card. This did the trick! The full video I recorded, short or long, played without stopping. Interesting, I recently had a similar SD problem while trying to get a Raspberry PI microcontroller working. So, be sure to consider speed whenever using these cards.
Video quality outside is probably usable but recording while walking may be problematic. First, of all, the glasses (camera) are jerking around just because you're walking. Then, when you turn your head to look at something, there is another jerking to the video. A marvel of human life is that your brain takes care of all this jerking and what you see is more or less steady. More expensive glasses may include some kind of stabilization.
The next problem I noted was with exposure. It changed from "too dark", to "just right", to "too bright" frequently as I walked and was somewhat annoying. When it was "just right", the color was very good. I didn't notice any "white balance" problem as noted by another reviewer.
As also previously noted, the camera is located higher than you might be normally looking. So, if you want to have something more centered in the view, you'll have to lower your head. Maybe not such a big deal. I was never able to update the file date but you could probably do that when you move the file from the camera to Windows.
Now, back to my intended usage to document processes, all indoor. Of course, the dark lenses create a problem but I could pop them out. I tended to have "exposure" problems here as well and since I was much closer to the subject, the image at times became unusable for my purpose. Having to tilt your head down was also a problem.
The last thing I didn't like was that it takes about a 3 second button press to get functions to start and stop. 2 seconds is a more common time. I'm older and only have a limited number of "3 seconds" left.
Summarizing, this was a fun toy to play with, but, I won't be using it for my intended purpose. The next thing I might try is to mount my IPAD around my neck and record with it!
