Would the SG9663DR be more resistant to high temps? Or more specifically sitting in the sun all day with parking mode enabled? Since the main DVR will be able to be tucked out of the way and be out of the sun, it should have a lower temp.
I'd think that you might also be able to locate the main unit close to an AC vent. My fuse box is behind the glove box and one of the vents for the footwell happens to be located very close by. Active cooling from your vehicle's AC could make any issues of heat a thing of the past-at least while driving. Parking mode might still be an issue, but heat rises, so placing the unit lower in the car should still help.I must add that if makers could take advantage of the hidden main unit and so will have no problems making it larger, then it could also have a far better cooling solution and so for sure be able to handle / dissipate more heat.
BUT ! as i understand it SG will be sticking to a minimal main unit size and so probably also make it possible to use the DR as a motorcycle camera, in this case a am not quite sure if any additional heat tolerance will be a major difference, as the smaller housing will not have anything major in regard to being able to dissipate heat.
In this case the only gain will be that the main unit are out of the sun, and thats still a substancial heat source, so i do think there will be a plus here, just unsure of how large font size i will have to use for that plus.
Yes you can always gift the DCPRO to someone you care about, or sell it for that matter, it is just the form of the 2 that will be different, the image quality will be the same.
