This is another purchase from Andy @EMPIRETECANDY
Amazon.com: empiretech
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.
