The practical difference
The mainstream 4K two-channel install, where the front camera has to read plates and the rear has to hold up in court. By contrast, the BlackVue DR770X-2CH II: highway driving where motion blur, not resolution, is what loses the plate.
On heat, the Viofo A229 Pro 2CH is a supercapacitor camera rated -4°F to 149°F, and the BlackVue DR770X-2CH II is a supercapacitor camera rated -4°F to 176°F.
