The camera was installed and used to work with no issues. I had an issue with my battery in the bike and had to replace it. I'm not sure when but since then I think the DVR stopped working, hence I have no led light and no indication of power. I tried to check the 3 pins plug and it seems that it delivers the 5V power to the adopter. (didn't check if it's 5, or 5.3)
At that point, I was sure that the DVR was damaged and not working, but today I used the USB port to provide electricity to the DVR and it shows the led lights.
I can't see the wifi network, but I read somewhere that it is expected when using the USB as a power supplier.
My question - is there a difference between the USB and the dedicated plugin terms of power input to the DVR unit?
Should I conclude that I need to replace the power exchanger unit?
any other suggestions or ideas??
