Rear facing camera.
I have been toying with the idea of buying a rear facing camera for my
commute in case of a hit and run event. However, obviously the cheap ones are low res and you are looking at 300 quid for a decent hi-res sports based camera. For a couple of quid though you can buy a standard 35mm camera screw mount which can then be attached to the bike. In this way you can get a 12 MP camera resolution for a few quid. On a test run it gives very good coverage of following traffic. http://img230.imageshack.us/img230/5528/pict0001gz.jpg http://img99.imageshack.us/img99/4459/pict0003r.jpg http://img176.imageshack.us/img176/4294/pict0004g.jpg -- Simon Mason http://www.simonmason.karoo.net/ |

Obviously the camera you have is not weatherproof and I'd be somewhat surprised if any consumer camera survived that vibration environment for any length of time. It might be better to fit it on a bracket attached to the saddle springs to ensure it has some vibration protection and is well damped by the riders mass. Alternatively if you like the complex approach try http://www.instructables.com/id/Upda...ted-steadicam/ The tripod attachment is usually a coarse 1/4in Whitworth thread, I'd be inclined to put a drop of low strength Loctite on it to prevent it coming loose with vibration. What sort of frame rate and resolution are you looking for? Not sure how successful it would be but alternatively you could do as I saw on a bike some time ago where the rider had got one of the large external security camera boxes (this sort http://www.alibaba.com/product-gs/22...amera_box.html ) and modified it to act as a storage box/carrier. He mounted it above his rear wheel and had pasted a picture of a security camera in the glass window complete with working flashing LED light. On it he had a sign saying "RECORDING". I never did find out how well it protected him. |

I'd like to be able to remove the fitting though. What sort of frame rate and resolution are you looking for? It depends on what size card I have. I have ordered a 32 GB card which will give 170 minutes at a setting of 1280x720 30fps. That gives a very good quality video image.

I think you must be suggesting that there must be a fair possibility of someone running in to you on your commute to work. Are you saying that it is dangerous? I suppose if you are going to go to all that trouble - then it must be. Will this be one of the 20 cars you see on your commute every day - or is it 35? You will be able to look at the footage and count them when you get home. Don't forget you will also be able to refine your figures for 6 or 7 having a headlamp out on every journey. -- Stopping distances for bicycles do not appear in the HC ... and so cannot be of any consequence.

I probably wouldn't use it in the wet as the lens would get obscured by spray anyway. So you won't use it when it is raining - when accidents are more likely to happen. Good value !! You must be quite worried about being hit. Do you think one of the 6 or 7 vehicle you see every day, on your way to work, with a headlamp out may not see you from behind? Did you say that you only saw about 20 vehicles on average on a journey. Now what's 6 or 7 out of 20 - that's quite a high percentage. Are you sure that's right? -- Stopping distances for bicycles do not appear in the HC ... and so cannot be of any consequence.

I can recommend the Kodak Zx1 which can manage 720p resolution at 60fps and is available hehttp://www.amazon.co.uk/Kodak-Zx1-De.../dp/B001SN72TK for £62.99. In red or pink it's even less, at under £50. You will need an SDHC card, and if you choose to record at 60fps it will need to be at least class 6, but if you record at 30fps you can manage with a class 4 card. Pretty much anything will do if you record at VGA quality. The camera comes with windows software, LSD NiMH AA batteries and charger, USB2 cable, HDMI cable, composite video cable, and a bag to keep it all in. A pair of AA cells gives about 2 hours of recording, which needs around 8GB of capacity on the card. A quick search of YouTube will easily find examples of footage from it, although it should be noted that YouTube compresses the hell out of it, and the original quality is much better. Cheers. I'll have a go with the Canon I've got first and see how that goes. I've got a 32 GB card now, so that is plenty big enough for the Kodak if I get that instead. -- Simon Mason |
