Registrar for the Volga 3110 with features. In which direction to dig?

Question

Electronics

The situation is the following. Need a video recorder. Three cameras. Salon, front and back. Conclusion of the desired camera on an external display (useful when moving ass). Shooting day and night. But damn, that's not the problem. How to implement the display on the camera of the included turn signals? I was just in a situation where the usual registrar is not enough. I walked along my line and decided to overtake. Behind me was a truck. I turned on the turn signal and started accelerating. Making sure that Kruzak sees the signal and continues to move along our own line. Gaining speed began rebuilding and then I kissed the sidewall of the miracle of the Japanese car industry. Since it was concentrated on the forward transport. In fact, it was all a matter of three seconds. But it turns out I'm to blame. He will say that I did not turn on the turn signals. And he turned on and went to overtake. At a speed of about 200 km per hour.
So I’m wondering how to avoid this and duplicate the turn signal from our Russian auto industry from the times of the USSR))). What functionality are you looking for? And is there such a thing at all.

Answer 1

How can a registrar help you?
If you, while overtaking, flew into the side of another car, this is your joint. And whether the turn signal was turned on or not does not matter.

Answer 2

There is a special class of industrial recorders for several cameras and the ability to receive external signals + GPS https://ru.aliexpress.com/item/DVR-4-1080-P/329599...
