I think that
@2000rpm has a Cobra 840. He may have some advice for you.
Yes, I have a CDR840E, along with several other cams (Nextbase 402G, Mio Mivue 538, Mio Mivue 528, Transcend Drive Pro 100, Cobra 820, Nextbase 101).

Chip set? Imager? Lens? General description claims "Full HD (1920x1080)". But specs section shows 1440x1080 30fps. What's the truth here?
I haven't been able to find definite answers to those, but based on what I see in its recordings.....
The chipset seems to perform the cam's tasks well.
The imager according to Cobra's manual claims 5MP.
The lens is probably F2.0.
Resolution is claimed 1440x1080/30fps (but seems to be 1920x1080) or 1280x720/60fps - and it's genuine 60fps (plus some low-resolution options which most people won't use except to economise on memory space).
Peculiarly, as I mentioned on another topic, the field of view is wider on the 720p settings than on the 1080p setting. I'd say F.O.V. is the stated 118 degrees on 720p but is probably closer to 100 degrees on 1080p.
However, the narrower F.O.V. means a more zoomed-in image and more concentration of what light the lens manages to gather, which can mean the ability to capture more details at longer distances than wider-angle cameras - but at the expense of capturing less of what's going on at the sides of the vehicle.
The specs don't sound particularly outstanding - and to be fair, nothing is outstanding - but the cam seems to capture details well in daylight.
A highly adjustable mount gives more mounting options than most other cams, although its shorter than average power cable can be a problem - I replaced my power cable with a longer one which I tucked around the windscreen trim.
