Firstly, there’s a difference between “sport” cameras and “safety” cameras. Some will conk out after an hour, some may run for two if you’re lucky.
The very popular Go Pro cameras produce beautiful footage but from a practical point of view, they are not designed to be a safety camera. When the battery runs flat, they’ll just stop, often with no warning.
For prosecution purposes, video evidence can only act as corroboration.
This means that you will need to attend a police station and give a written statement and must be prepared to attend court to give evidence in person. They must not rely on a perception of distance such as a close pass as the apparent distance will vary according to the type camera and settings.
These cameras record a series of files and when the card fills up, it starts overwriting the oldest ones.
This means if an incident occurs, you will always have the footage.
And there’s more to wearing a camera than just plonking any old bit of hardware on your head. A recent study in Australia looking at cycle-camera footage showed motorists were responsible for 87% of accidents or near-misses with cyclists, mainly due to lack of driver awareness. But if something goes wrong, wouldn’t you like to have a record of the incident that you could show to the police? With a helmet safety camera, if something happens you’ll have it all on film.Asheville On Bikes shared the video, saying the cyclist was riding legally in his lane and not impeding traffic.Watson was accused of tailgating the cyclist before trying to run him off the road.Some people have been known to carry out online naming and shaming campaigns with their footage, but see this Guardian post about what happens when that can go over the top.Others have reported that approaching the insurance companies of the third party can be a useful strategy. During the time I was putting this post together, this post on highlighted a case in which a van driver was fined and had points put on his licence as a result of video evidence.
