Hi, I'm Henry and new to the forum, I am an automotive technician
Some may think this should be in the automotive thread, but I think I'll get better results here.
So, I installed a dash cam that is basically a bigger rear-view mirror, this:
https://www.amazon.ca/TOGUARD-Waterproof-170°Wide-G-Sensor-Detection/dp/B07DN8Q8Q6
It is powered by a USB that runs off the cars ACC plug(cig lighter), so 12-14 volts to (usb) I think about 5 volts converter.
It only runs while the ACC socket is powered, and the dash cam shuts down when acc socket is live.
What happens is when the dash cam initially turns on, there is a display in the mirror glass of what the cam is recording, then after 30 seconds that image turns off so you can use the rear-view as its intended for.
My 2017 Ford Escape is wired so the acc sockets are always powered on, so the cam would never shut down.
I bought USB hardwire kit that only is powered with key on, and it works great: This:
https://www.amazon.ca/SHISHUO-Dash-...+volt+kit&qid=1553553104&s=electronics&sr=1-5
So here's my problem;
My vehicle has a feature called Auto Start/Stop, basically when you stop with your foot on the brake pedal and vehicle is in gear( waiting at a stop light) the engine shuts off and will remain off until you lift your foot from the brake pedal or put it in park, then the engine automatically restarts and away you go.
What's happening is there must be a momentary voltage drop in the fuse panel when the engine auto re-starts and what happens is the recording image pops back on the display for the 30 seconds which is annoying and blocks my rear-view for that time.
It will not do this if I use the provided ACC plug, but I want to use the hardwire kit I installed so I don't have to keep unplugging and plugging in that ACC plug, I bought the hardwire kit so it is a " set it and forget it"
Would a capacitor in-line with the 12 volt feed hold the voltage momentarily while the vehicle re-starts? I know something greater than 15 volts is needed but, What rating of cap would you use?
Thanks
