I have a Hikvision CCTV system installed with a DVD recorder.
I have purchased a EZVIZ DB1 video doorbell thinking that I could easily add this to my system.
However when I looked how to connect the power supply, the instructions only refer to a door chime having 3 simple connections - Transformer, Front, Rear.
My door chime is a Freidland 991 model with 4 connections - 0, 1, 2, 3 and whatever combination I try, I can't get it to work.
Anyone any ideas?
