Self Contained Micro Cams

Self contained cams are very popular now and getting better by the month. They offer a simple, all in one solution. No wires, no tapes, just ease of use. The two cams below are in a class I call "micro cams". There are more cams of this size out there, but these two seem to be the most popular "Micros" at the moment.

They both easily fit in the palm of your hand - on my bike double mounted for side by side testing.

Out of the box. Both cams are packaged very nicely in minimal cardboard packaging without a lot of "fluff" so I would give them both the green thumbs up for that. The Epic currently comes with more mounts than the Tachyon. Both have cables to connect to your computer and Tachyon has an additional cable to plug into your TV for viewing your video.

Cam set up and mounting. For testing or making my own videos I often make my own mounts, as this seems to be a bit of a weak area in the "sport cam" industry. For this test I made a side by side platform and installed a ball joint from RAM mounts. This way I can position the cameras in whatever orientation I wish. In this case, side by side off the back of my mountain bike seat post. Additionally, the more SOLID you can mount a camera, the more stable your video will be. Actually, I only run a helmet mounted cam if I'm going to be doing a fair amount of panning shots or need a detached camera.

Shooting video. The Tachyon has gone to simple with a single button for on/record and off. This simple approach I feel is great, it keeps you from accidentally being in the wrong mode or erasing files etc. If you want to change the mode you will need to open the back and flip a small switch. The Epic has two buttons and has a fairly sophisticated range of options. In both you really need to pay attention and learn what each beep sound means. (I wish there were an industry standard for record and stop, power on and power off beeps!).


  Epic Wide Tachyon Micro
Image Clarity fair very good
Color quality fair very good
Contrast fair good
Lighting compensation fair (flicker is evident) good
Smoothness of video fair very good
Sound quality OK, but poor inside WP housing poor (waterproof design)
Mounting system good fair
Battery life no data yet no data yet


Epic Stealth Wide - Pro's:

  • Sleek compact design

  • Good mounting system with many options

  • Comes with batteries and memory card

  • Waterproof housing included (but lens scratches easily)

  • Sophisticated menu and options (If you like that)

  • Wide 168 degree lens - if you like wide and don't mind a bit of distortion

  • Light weight (out of the waterproof case)

Epic Stealth Wide - Con's:

  • Generally disappointing video image

  • Price is high for this quality of video

  • A little flimsy on the build side, like the battery door compartment

  • 4GB SD max memory storage? (needs to be verified)

  • Does not handle low light very well

  • Uses expensive disposable batteries


Tachyon XC Micro - Pro's:

  • Excellent video - color, contrast, smoothness, sharpness etc.

  • The price is nice

  • Very rugged design (claims to be shock-proof)

  • Waterproof to 34 feet

  • EZ one button operation with LED verification

  • Large memory storage capability (up to 32GB)

  • 90 degree field of view - just about right for all around shooting

Tachyon XC Micro Con's:

  • Mounting system - only comes with one mount and that mount makes it's size 15% bigger

  • Sound - basically unusable, granted it's a waterproof cam as is

  • A little on the heavy side, but it's built TOUGH

  •  Uses expensive disposable batteries

Bottom Line:
There are a few wishes for both cams but as far as the actual video goes these two test videos pretty much tells all. Sunny bright conditions example HERE  and cloudy overcast example HERE. This HelmetCamReview shootout has a clear winner in my book: The Tachyon XC Micro. It's superior video quality and great price will be sure to sell many of these units. They just need to work on their mounting system and they will have a real winner at a bargain price. Thumbs up and good job Tachyon.

Tachyon XC Micro wish list:

  • Move LED indicator to front of camera, or add another one.

  • Maybe a 120-130 degree model for close up action (like surfing or sailing).

  • 1/4 x 20 threaded mount, bar/tube mount and vented helmet mount.

  • Rechargeable LiIon battery pack


Epic Stealth Wide wish list:

  • Improve overall video quality

  • Add record/standby LED to front of camera

  • 1/4 x 20 threaded mount

  • Include spare plastic lens cover for waterproof housing - or go to glass?

  • Rechargeable LiIon battery pack

Other notes and wishes:
One thing that happens with all these self contained cams (except the VholdR cams with their positive sliding switch) is that occasionally you are going to miss video because you are in the wrong mode or the cam isn't even on. If you mount the cam on your helmet or any distance away from your own eyes you are dependant on hearing beeps or feeling buttons. On the tests above I missed video with both cams and a bit more so with the Epic (It's two button operation is more difficult when going by feel/hearing). I would love to see a two way wireless (or wired, yes wired) control button with LED, in other words a LANC control. This would allow remote positioning of the cam with a positive way to make sure the cam is recording. Not a remote mind you, a remote cannot tell you it the cam is actually on. You need something with feedback, hence the LANC.

Threaded lens mount. The addition of threads on the lens area would allow for addition of lens covers, wide angle lens attachments and filters, or even another way to mount the camera.

External audio plug in. Wow, if one of these cam companies could figure out a waterproof plug in for an external microphone that would open up a lot of possibilities!

General notes about MOUNTING SYSTEMS
Almost all cams in this category have mounting issues, none is perfect. I tend to make my own using RAM mounts. The exception is the vented helmet mount, of which VholdR, Epic and others have gotten about right: A snug mount on two adjustable straps. Before VholdR made theirs, I made my own HERE. Don't be afraid to be creative and make your own mounts! Remember YOUR point of view might me a little more interesting!

Notes about AUDIO/SOUND
Even though I do not use much of my native audio from my cam shoots (I usually put in music instead), it's a big bonus to have it. It adds to the moment, a short chat at a break in the action with your friends or whatever. A few of these companies have opted for water-proofness over audio but I really hope they can find a way to do both!
