This model allows you to detach the camera from the mount, so if I park in the sun that is what I do. Although I park undercover 99% of the time. If you require a dashcam that is better at withstanding the heat, you need one with a capacitor and not a battery and one that attaches with double-sided (3M) tape is better than the one with a suction cup, but then you can't remove it as quickly.
I had two GS98C's that I imported from China and they both broke down within the first week, so local support is important. These ones that TopCCTV sells have a 1 year guarantee, so that should give you some peace of mind.
And you don't
have to shop at TopCCTV, I am a registered dealer with them, so I get a better price.
You can also buy the same model at:

or just google Eagle Eye Dash Cam V2.
For interest sake, you can find sample videos here:

But there are also other thing to consider like resolution (4K vs 1080P vs 720P), FPS (30fps vs 60fps), GPS enabled, one camera or two, quality of night time video, field of view, clarity of sound recording, price, etc.
Another recommendation that I can make is to buy a good quality micro SD card. I always buy the Samsung EVO range and never had any issues with them. They are a lot quicker than other class 10 cards with writing HD video and they are more tolerant to the warm environment.
