Why wouldn’t they?... is a brand new camera.. Member Hulk just posted persistent issues with possible thermal induced shutdown. There may likely be others here in this very forum, as well as out in the real world, in more heat intensive climates, who do not post here, yet have related issues. My original post clearly identified its intended audience in the first sentence. Since your unit is 'behaving', then my post obviously does not apply to you.
They do have the choise of returning or exchanging it.
I had my complains about the 900 2ch cam.. and here in this group.. I said they would fix it. ... some one replied... yeah.. with a new model. ... well... they have fixed it. ... Just because your workarounds with altered settings and updated firmware work for you, does not mean you speak for everyone else.
when you buy this new.. you have 2 options..
trust the brand... or return it. No. You have a 3rd option: try and improve/hack the design. Excessive heat buildup, as you may well know, is a critical player in the accelerated degradation of components - especially the sensitive electronics inherent to this unit. Additionally, Blackvue itself identified this particular model as having a lower thermal threshold compared to previous models. Improving the housing ventilation as previously mentioned may further help. How much is uncertain. More data/testing required.
Same thing happened with my 2017 Toyota Tacoma... guess what?.... they fixed it. Irrelevant to the topic. Nobody cares about your Tacoma.
Blackvue has done... just that. Time and greater sample size post-'fix' will tell.
