I installed a B4K dashcam with the hardwire kit. It appears to only work (turning on and changing between parking and normal mode) with the voltage cutoff set to 11.8V but my car shows about 12.4V when testing voltages from the fuses. Any resason that it doesn't work with higher than 11.8V setting?

I'm planning to get a B4K which is mounted by adhesive. To prevent overheating when in the sun, I'm considering sticking a bent piece of shiny metal under the headliner and mounting the dashcam to it. The shiny metal would reflect the sun and not conduct too much heat if I use steel. Hopefully...
