How to host video doorbell wiring and indoor extension? A total of eight lines.
This is a 7" LCD Color Hands Free Video Door Phone & CMOS Camera
 

I'm sorry, I don't understand the question: Do you mean extension cables ? We had to trail a door intercom's phone & lock release multi-core wire around the outside of the house. IIRC, we used a drum of 'alarm' hook-up cable. For video, we went wireless...
 

I wish to take an ordinary intercom doorbell ,but i dont' know what was happened, not see video.
I check it and voltage stability....
thank you
