Hi Guys,
I have my Lukas now for a few month and the car is sitting in full sun. Since I drive only ~600 miles a year (yes a year) the car is sitting. I get +120F here in Florida (once checked at 2 PM 135F) in the car in daytime and the camera works perfect, did not shut-off. The front windshield on the car has no shaded area in front of the mirror either. Memory stick 64Gb, from time to time I take the stick out, to my laptop and it is hot, almost burns my fingers. I take the stick out to upgrade the firmware. All in all, it exceeds the max specs from Lukas. I am lucky it works that great. Picture quality is excellent except I can't get the filter to work, I have dashboard glare in my windshield and recorded too, with or without filter.
I record 24/7 parking mode, extra battery in the trunk, lasts ~ 3 weeks, camera is not connected to my regular battery.
Anybody with problems, try to exchange the camera.
George
