Beware, this forum does not auto save and after writing quite a lengthy post on my experience of running front and rear dashcams, it's decided to lose it. Once bitten.........
Sorry to hear that, but the Forum didn't decide to "lose it" for you. You must have accidentally deleted it yourself somehow, or possibly your internet connection blipped. You could of course have tried to find a cached copy on your computer. Your operating system might have saved a copy in your internet history. Having just done a bit of research, there is very little evidence of any public internet forums that actually do have Autosave.
However, a salutary warning, that when making a lengthy posting it might be better to do it in a text editor such as Word and then copy & paste onto the forum.
Yes of course, I'm working on an iPad as I can't use my desktop so I'm sure it (the iPad) refreshed the page or something similar. I used the wrong term by suggesting the forum refreshed. It's a risk when alternating between this forum and photobucket. It would be better to copy it out of Word or similar program but it makes adding the tags for the photo links more difficult. Sorry for giving the wrong impression.
Rather than try and add photos which I might when I can sit at my computer, I'll just document a couple of important points that were lost as above.
When adding a front camera, you need to run the wire down the front A pillar. It is attached to the window frame with a fixing that is intended to be sacrificial and snipped off but by pulling the trim back, it is possible to use small tools or picks to release it from the window frame. It is then assembled and pushed back as one. The main point to make is that the power wire must not be tucked under the door seal but tie wrapped above the curtain airbag so that trim needs to come off.
Putting the supply cables into the accessory plugs is the best solution as the cameras power down with the key out. Take care that in a lot of cases, the voltage is dropped from 12v to 5v inside the plug and snipping the plug in order to hardwire the camera will almost certainly destroy it.
When running the feed to the rear camera, I made a mistake by running it through the right side gaiter but that also holds the wire to the DAB/radio antennas and it completely messes up the radio reception. I will modify mine to simply run a 12v twin core feed from the plug in the boot, right round the bottom, up the left side and in through the left side gaiter, well away from those antennas. I will just add an accessory plug inside the boot and plug the camera in to it inside the back door cavity.
Finally, if that back door seal is pulled back, it is sealed with a non setting white mastic that makes a proper stringy mess. Keep that in mind and remove the parcel shelf and have some decorating sheets around because it doesn't easily clean off.
