I apologize for going off topic.Boy talk about some members going off topic!
If you're happy with your camera that's great.
If you're concerned about the heat then I believe it would be a sensible move to remove it from the dash when not in use on hot days.
I think the ability to handle hot temperatures is one major differentiator of Korean vs Chinese made dash-cams, or at least was in the past. The Korean ones actually list the max temperature as part of their specs. Not sure about the other ones.
A 1080 resolution dashcam.My old Lukas never let me down for more than 6 years in the super hot Arizona sun.
I hope my new Blackvue will last as long as well.

All major manufacturers (70mai, Garmin, Viofo, ...) state the operating temperature, and it ranges from 60° to 65°C, regardless of whether they use a capacitor or a battery. Viofo for the A119 mini 2, for example, states the maximum non-operational temperature, but only 70°C, which is not enough in the summer, so the camera should be removed from the windshield. It is similar with other manufacturers.I think the ability to handle hot temperatures is one major differentiator of Korean vs Chinese made dash-cams, or at least was in the past.

The issue on this thread is the use of lithium ion batteries in 70mai dashcams. Cars also use batteries, you can expect to replace the main car battery at around 6 years, sometimes less, and the car keyfob battery at every service, so I think it is reasonable to expect to replace the dashcam battery occasionally. Some dashcams, such as Viofo, have the advantage of not having a battery, so no need to replace it when it wears out, but for those that do use batteries, they are going to wear out.Not trying to be argumentative, but if a dashcam is being sold for use in a car, it should be a given that it must operate wherever a car operates.
Anything else means poor engineering and customer deception.
The customer doesn't need to, but if they do then they will extend the life of the battery, and it doesn't take much effort to extend it from around 18 months to 5 years.It is not reasonable to expect the customer to remove the dash-cam from the windshield because of heat,...
I think it is reasonable for it to shut down in parking mode if the air temperature in a locked car is getting up to 90°C.or for the camera to shut down to "protect" itself.

Personally I'm in the same camp. Protect the car, not the dashcam. Ideally you want a dashcam that's always there, set-it-and-forget-it, so you never have to putz with it, forget to reinstall it and plug in the cables, etc. What are you gonna think if you take down your dashcam one day, only to come back to your car and find that something happened and now you've got no evidence? Sure it can be a pretty extreme situation to deal with high heat, no doubt about it, so if that's an issue, ideally you'll want a dashcam with a supercapacitor that's optimized to handle higher temperatures and then handles its own thermal management and overheat shutoff protection as needed.Not trying to be argumentative, but if a dashcam is being sold for use in a car, it should be a given that it must operate wherever a car operates.

Image a car alarm doing that.
Excellent. I agree. But I don't know of any commercially available cameras with a capacitor that can withstand higher temperatures (for example 75-80C). So far, I have not been able to find a single camera that would work at over 60-65C, regardless of whether it is with a capacitor or a battery.Personally I'm in the same camp.

How do DVRs maintain time & date when turned OFF?
RTC BatteryAnd if so, are they effected by heat and should be replaced once a year or two?
Seems like Viofo is using a tinny battery. Too bad.
