Been looking into something like this for a while. How long have you had this unit and how reliable has it been?
I have 2.
One is the original unit which I believe was designed and developed by a company here in the UK called DogCam.
This had a few issues which were resolved around the same time that the unit started to be marketed by RoadHawk.
In particular, with the early DogCam and a couple of other units that I have had - although the unit itself has been sturdy, the mini-usb type connections have been fragile, and it is these that have failed.
However, with the RoadHawk R+ Moto, this has been sorted. The hardwire kit to the bike battery comes with a special cap. The power lead plugs into the rear of the camera, and the cap holds it in place. However, it is designed with a locating pin which locates in its hole before the Mini USB makes contact with its socket. In this way, no strain is ever put onto the USB socket when the cap is being put on or removed.
One issue with the earlier DogCam unit came about by turning off the ignition before the camera had finished initialising, and then turning on again. It happens sometimes when starting out on a ride. The camera would freeze and stay frozen until its reset button had been pressed. Mine did it to me on Friday for the first time in ages, but the RoadHwak R+ Moto continued recording. I have both cameras switch on with ignition whenever i go out. So I am pretty sure that this fault with the original dogcam has been fixed. Certainly the RoadHawk has never frozen on me.
Picture quality is pretty good - better when the way ahead is lit up in strong sunlight, but not bad at other times either. There are some models around that are better quality though - at a premium price. With the better quality comes larger file sizes, greater expense in larger memory cards, and extra time processing the files afterwards. You pays your money an takes your choice.
For me, I'm perfectly happy with them. They are compact, work on internal battery and with battery power, the auto light balance is pretty good, and the sound records OK even with the waterproof cap on the rear.
Disadvantages - you cannot see what you record, nor can you delete files from the camera - you have to access the card, or remove the card, and use a computer. I looked at options to provide this facility, but decided that the cheapest way was to buy a whole load of 32Gb Micro SDHC cards for long tours. I just switch them out every day.
To answer the question directly - I bought the DogCam version about 4 years ago. The RoadHawk 2 years ago. I had issues with the Mini USB socket, and that camera was replaced - but as already noted, the RoadHawk unit has solved this issue.
I put them both on the bike every time I go out, and apart from that glitch with the usb socket, they have both served me well . I take the cap off each time I return and replace the memory card. They have both remained completely waterproof, and the units themselves are very sturdy - both having been dropped from seat height onto concrete and tarmac many times without any ill effects.
The camera needs fast memory cards - Class 10 or up really. It also responds well to having the cards formatted rather than just deleting the files. Quick format is good enough. I don't know why, but it does.
Let me know if you would like video in different conditions, or what else comes with the kit, I'll see what I can do.
(Nb - looks like the Roadhawk USA site doesn't list the R+ Moto camera. I found a couple of Amazon sites that claim to have it at around $250.)
