I bought a townhouse and the previous owner replaced the front gate bell with an Aiphone. The inside unit is a JK-1MD and outside is a JK-DV I believe. The only thing that works is the gate release. The video and intercom and bell do not work.
They used twisted cabling (like phone cabling- probably Cat3). The manual says not to use twisted cabling.
I brought the camera part inside and wired with twisted cabling (only 2 m long) to the receiving unit and it worked.
I did a continuity test on the wiring to the gate (maybe 15-20m) and the wiring is good.
There is no way to replace the wiring to the gate as it goes underground and through many walls. Is there anything I can do to get this working? If I can even get the buzzer and voice to work without the video, I'd be happy.
