open topic, for anything cycling related.
It's important to look at the cameras specs. There are some sellers out there that are selling cameras that are advertised as being HD but are only SD. So it pays to be careful when buying a camera.
HD (High Definition) is much more preferable to SD (Standard Definition). When using a HD camera videos are clearer and sharper than SD and when you are trying to capture number plates, the more detailed the better.
Things to look for are video format. High Definition will typically have a movie format such as .MOV, H.264 compression. Resolution will be something like 1080p = 1920—1080 pixels (16:9), 30 fps, 960p = 1280—960 pixels (4:3), 30 fps, 720p = 1280—720 pixels (16:9), 60 fps, 720p = 1280—720 pixels (16:9), 30 fps.
Standard Definition will typically have a video format that is either AVI, or MJPEG. The Resolution is something like, 640 x 480 or 720 x 480 and some maybe up scaled from 640 x 480 to 1280x960.
Try to avoid cameras that use M-Jpeg video format.
Motion Jpeg is one of the oldest video formats, unlike MPEG or H.264 formats, M-JPEG takes a very different approach to video compression. Instead of compressing the entire video as a whole, each frame is compressed as an independent JPEG image, and strung together to make a video sequence.
The downside of Motion JPEG is, video playback can also be quite jerky and it does not use any compression, because they are already Jpeg images, so the resulting video files can be quite large. A H.264 encoder can, reduce the size of a video file by more than 80%, compared with the Motion JPEG format and as much as 50% more than MPEG-4, without any loss of image quality. JPEG also has a problem with sharp edges which is unavoidable, partly because the standard was meant to compress natural images like scanned photographs.
Lens Viewing Angle
Some cheap cameras will have a viewing angle of approx 70º, this is pretty narrow. While others such as the GoPro have a viewing angle of 170º ultra wide angle in 720p and 127º wide angle in 1080p.
The advantage of wide angle is that it allows for a lot more action to be captured on camera. Depending on what you use the camera for, 70º maybe to narrow, while a viewing angle of 170º tends to give a Fish Eye affect and some people don't like this, but it captures the most action. 127º is the probably the best all round viewing angle.
Another thing to keep in mind, is the narrower the field of view, the harder it is to line the camera up properly. The cheaper cameras do not have a built in screen, so it can take a few tries before you find the correct recording position. The mid to high end cameras usually come with either a screen or laser, this makes lining up a lot easier. If the camera has a viewing angle of 170º all you need to do is face the camera forward and chances are it will be capturing what you want. Although after viewing the footage you may need to alter your mount to get it cantered properly.
Here is an animation I made to show you the different viewing angles.
Thanks and you are right about the corners, it was a rush job. I just wanted to show that the plastic base could be used to make the mount, If someone was to take the time to do it properly, they would have a very nice mount for the fraction of the price.
If I was going to make one to use myself, I would have the corners nicely rounded and have some thin rubber wrapped over them. I would also incorporate some elastic in the straps on the shoulders and on the side straps. This would help to make it comfortable and allow for body movements.
If you want a cheap camera get yourself a Jumbo 808 #11, I have 4 of these and they are an excellent camera for cycling, because they are small they are really easy to mount in a lot of different positions on the bike. I have mine mounted on the front wheel and rear wheel quick release. You can buy a handle bar mount for them for about $10, the mounts works very well and holds the camera nice and tight.
It looks like a remote for your car and costs approx $40. It is HD (High Definition) 720P high Definition Video 1280 x 720 H.264 30fps.mov. 5.0 Mega pixels Photo JPEG format: 2592 x1944.jpg.
Battery time is approx 1.5 hrs, but if you want to record longer you can get an external battery pack for it, this will allow a recording time of approx 4hrs.
It is not water proof but if you check out my DIY mounts section >>>Mounting FAQ’s - DIY and Third Party Mounts>>> you will find a few different types of cases for it. You will also find some easy to make mounts that are nice and stable.
It does look good on paper and seems to have everything, but I would be waiting for it to be reviewed a lot more.
Everyone's needs are different, but for me, If I wanted a camera solely for cycling I would be looking for something cheaper, I have the GoPro but use the jumbo's on the bikes, because they are cheap and small. If something happens and I lose one or damage it, it's not a big deal, they have no problems capturing plates.
I use the GoPro in the car when driving and have it mounted to the bottom of the rear view mirror and I use it as a family video recorder.
The Contour GPS was good in low light I thought, albeit a little grainy, on the low light setting. Number plates were mostly distinguishable unless moving your head through large arcs. The Swann Freestyke HD 1080P that I have in front of me isn't quite to the same standard but still quite reasonable. GoPro probably not so good, but this is subjective and based on my dodgy memory.
I had planned to do a back-to-back GoPro/Freestyle low light test with both cams going simultaneously, but not planning very well and pressing the wrong button on the Freestyle stuffed that idea. Would have caught an epic abusive moron motorist close-passing me Thursday at Taronga Zoo with reportable footage.

Most of these cameras will not do well in low light, they are designed as sports cameras and as such will function really well in bright light but will fail in low light.
Googles glasses looks to be the next evolution.

At $500 it will give GoPro a run for its money.

On the ion, I am organising a review for BNA and will involve trailgumby who (as you can guess) is pretty fluent with bike cameras.
That’s me being a smart alec
It’s Japanese meaning “different” or as I understand it “I disagree”.
I’ve used glasses with inbuilt camera’s.
Here’s a sample from my YouTube channel (apologies for music selection but .... meh, I like it)
Video camera’s mounted in glasses can’t compete with GoPro or Contour because these two camera’s have superior mounting options. For sure there is a place for glasses with video camera. If mine didn’t die I’d still roll with them.
Again, apologies for being an idiot in my previous reply. When I disagree with someone I say “chigau” much to my wife’s annoyance and my friend whom is Japanese, amusement (probably because I’m saying it wrong as well as pronouncing it wrong)

If you watch the Google Glass presentation, I notice that some of the sky divers were GoPro sponsored and one of them had one on a chest mount.
I was wondering if they were using other camera (in addition?) for the live streaming.
Have to do some more reading on the google solution to see what the headup display does. For a cyclist it could be a rear view mirror (i.e. seperate rear view camera streaming to headup display - as a glass mounted camera wouldn't see past a helmet (let alone helmet hair).
An exciting option if it was affordable.
I enjoy researching the different cameras and I really enjoy helping others with their questions.
I would think the cameras like the GoPro, Contour etc will evolve over the next couple of years, there are a lot more manufacturers bringing out action cameras and they will need to have cutting edge designs to stay ahead of the pack.
One guy also had a GoPro on his helmet, I was also wondering how much of the footage was from the glasses and if any GoPro footage was included.
The biggest problem I can see using a glasses camera is, the head is not always straight up and looking forward. It would be good if the Google glasses had an adjustable lens so one could raise or lower the lens depending on what they are doing.
Here is some information I have come across for the Ion Air Pro WiFi v's the GoPro 2.
Looking at the specifications of the Ion, it has the same size sensor as the original GoPro - 1/2.5" HD CMOS, the GoPro 2 has a slightly bigger sensor - 1 /2.3” CMOS.
The Ion's light sensitivity is 1.4 V/lux-sec, this is the same as the Original GoPro. The GoPro 2 is .84 V/lux-secs, the GoPro 2 performs better in low light.
Battery life for the Ion is equal to the GoPro which is approx 2.5 hours, you can however purchase a battery booster for the Ion which is a 1800mAmp battery the battery booster allows camera unit to charge twice without the need for an external power source to provide over 7 hours of battery life. It seems to be an external battery though and is not built into the camera
You can also purchase the Battery Backpac for the GoPro that will increase recording time to approx 5 hours, it also includes not only the battery but also a Skeleton Door and Water Proof door.
It seems that the Ion may suffer from Chromatic Aberration, colored fringing around objects in bright light, usually purple, red or blue. The audio is also reported to be worse with wind noise, to the point that audio is not usable. But most of these cameras suffer in the audio department.
What I did find out was that the mounts are supposedly very good and easy to use, apparently it is easier and quicker to attach than the GoPro.
By all accounts, the build quality is on par with the GoPro, but unlike the GoPro it does not need or have a housing and will handle a lot of punishment.
And of course there is the WiFi which when used with a smart phone or tablet lets you see what you are shooting. The GoPro 2 is purely guess work unless you purchase the WiFi Backpac.
The memory used on the Ion is Micro SD, the cards may be cheaper to buy than the SDHC the GoPro uses.
The size of the Ion would suit a lot of people, the GoPro 2 can be quite bulky looking and when you add the BackPacs it get bulkier. The Ion weighs a little less than the GoPro.
I am looking forward to Trailgumby's hands on review, it will be interesting to see how much of the above applies to the Ion. It may well prove to be up there with the high end cameras.
Music wasn't that bad, who was?
Now. IIRC, you said at one stage you didn't mind your riding being critiqued...
Sit waaaaaaaaaaaaaay over to the left like that and you give the clowns room to treat you with disdain. Seeing as we are not fitted with indicators, it has worked well for me to use my position to give the sentient smokeboxers an idea of my intention. The rest of them have to be allowed for of course but by taking an assertive position on entry, you prevent them acting on their ignorance.
...whatever the road rules, self-preservation is the absolute priority for a cyclist when mixing it with motorised traffic.

It’s “I was born to Cry” by Johnny Thunders. It’s on a compilation CD I’ve had for donkeys ages. The Video was from early January this year and thanks to the advice I received on BNA I have since improved my roadcraft at this RAB which I ride through every day on my commute. I now “take the lane” before coming up to it.
The video was taken using a pinhole camera in my glasses which are good but with limitations. The camera is in the middle of the frames (just above your nose) but the angle isn’t quite what you see with your eyes. Unfortunately the glasses died and at roughly $150 I’m not sure if I’ll replace them.

Is this the "correct" Jumbo to get? (ie are some better than others?, are some genuine 720P & other interpolated?)

Thanks Pushy, that RCGroups forum has some great info...
Seems there are 720P #11's with 120 deg lens, and new key chain style that do 1080P@30fps or 720P@60fps but with only the std 67 deg lens (120 deg lens expected later in the year)... so decisions, decisions...
720P@60fps with 120 deg lens for $50 would be ideal imo (but what do I know... I'm very much a noob on cameras)

I posted a pic of the Jumbo at the top of this page, there is also an animation that shows the different lens angles.
From what I have read, the new 1080P does not last as long as the 720P model, Mine lasts 1.5 hours and the 1080P only lasts 1 hour.
If you want the 720P grab it from here,

Some might remember the Hindsight camera that was posted quite awhile ago. For those that don't know of it, it is a safety camera, it has a lens that mounts on the rear of your bike and a video screen that is mounted on the bars. It acts as a rear view mirror. It records video in 5 minute loops and in the event of an accident it will stop and save the recording.
It has been in development for quite awhile, but is now available for purchase.
Some of the features...
The systems records video in a continuous 5-minute loop, stopping automatically if the bike is laid over.
Rechargeable internal battery offers over 5 hours of run-time (*set at highest-resolution)
3.5" Transflective LCD Screen
The 3.5-inch transflective color screen presents crystal clear, real-time rear views and is readable in bright conditions. Not for use with polarized sunglasses.
Downloadable upgrades will be available for Hindsight 35 so you will always be on top of the latest technology.
Includes speed, max speed, average speed, trip distance, odometer, stopwatch, and time. Heart-rate and cadence are optional accessories.
