Re: DIY: Hard-wire your Dash Cam without expensive hard-wire kit The 70mai dashcams cannot be 'hardwired' so easily now.
Most of them recognize a real company OEM hardwire kit as opposed to just using a 5V USB solution, even if it is always powered on.
As a result, card-saving features like 'time-lapse recording' are disabled unless one uses the aforementioned hit.
However, nextdigitron now makes their own in-house alternatives.
There has to be a way to bypass such a 'guard'. Often, companies do it by bridging the data pins with a fixed resistance resistor.
Any such luck/ideas? I have multiple A500S and am fed up of paying for proprietary hardwire kits that do NOT cut off at 12.2V+
They cut off at 11.4-11.6V which is VERY BAD for a diesel car long-term.
I'd rather combine it with an LVCD where I can tune that it runs only at 12.2V+ so I have enough reserve juice to crank.
