Technical person to install a dash cam, front and rear.

I bought a NextBase dash cam from Halfords in the UK.
Front and rear. Had my car left wing damaged.
Need some one to fit it. Wired in.

Try Lynn & her Hubby as if my memory is correct hes an expert at fitting & fixing them as he did that in the UK but just in case im wrong Apologies in advance.

I have had it fitted by an auto electrician from a garage. With receipt and everything. Just for insurance reasons.
I need to be shown how to do the technical things. Need to be able to see my car from indoors or away from the car. I have downloaded the manual, but is always easier to be shown how. So if you could help I would really appreciate it.
