This is another purchase from Andy @EMPIRETECANDY

Haven't been able to test much yet, so far:

IR is very good
Great microphone
4k quality is outstanding (footage to come)

Below are a few pictures.. Had some difficulty finding the reset button but was easily found by unscrewing the board. Its located underneath along with the sd card slot. (My first turret, plus got some touch up work to do. Just got rid of satellite and they butchered the house )

Thanks to @giomania for the advice to remove board.

The sound quality is very good as well ...
Would be interesting to see how this camera works with no IR at night.

Thank you for sharing.

Don't want to speak for anyone selling but they are around the same as I paid for the 2mp varifocal starlight. $150-$170 each. Got a great price from Andy on 2 of these 8mp but I don't know if we are supposed divulge the info. I emailed him and he got back to me right away. Haven't received them yet.
