Need help replacing old BPT 200 Surf video intercom
Hi guys, I found a client with this old BPT 200 Surf video intercom system that apparently stopped working.
I’m trying to understand if I can replace only the indoor unit with something universal, or if I must use another BPT/CAME compatible monitor.
The system has many wires and doesn’t look like a simple standard analog intercom, so I’m afraid of buying the wrong replacement.
Does anyone know if this is a proprietary BPT system or if there are universal compatible monitors?
Can I replace only the handset/monitor or do I need to change the whole system?
I attached photos of the wiring and monitor. Any advice would be appreciated because I don’t want to mess up the installation.
