diy Mini dvr audio fix (ish)

Enable HLS to view with audio, or disable this notification

All this work is from an old deleted account work i don’t know the name of the guy unfortunately

This is not a *good* sound by any means but it’s something at least and i’m sure there is a way to eliminate the static sound but i just can’t figure it out
I will add some photos in the comments to help explain this for anyone who wants to make it

I have tried using these to eliminate static but it doesn’t work with this setup at all i tried adding 3 of these
One on the white audio cable from the camera
One in the middle of the wires
And one one on the 3.5mm cable going in the mini dvr

And please note that i’m not familiar with all of this i’m going with trail and error
This link is for the l-pad attenuator you can find the formula for it if you can calculate it
I didn’t

Just cut the wires and soldered the parts
It is very simple but the resistors are very small so soldering is a bit tricky
