I would like to install an intercom on a building with 3 apartments.
So I thought of this Dahua VTO2000A-C + VTO2000A-B (3 button module).
They must be connected to their POE switch VTNS1060A and to 3x 7'' internal monitors.
Both external unit + 3x internal monitors are to be connected to the switch that must also be connected to one router with Internet connection (to show video also on the smartphone).
Well, the point is, one of the tenant must provide the Internet connection to all the system (it should be absurd paying for a dedicated line only for this task...): that way, hypothetically, one in other apartment could disconnect its monitor and connecting to the RJ45 cable will have access also to its LAN! Besides, even someone that could reach the site of the switch, could access the private LAN.
1) Is it correct? It seems a bit too much insecure system, isn't it?
2) Are there other solutions to avoid this situation? I saw one Dahua 2-wire system: could this solve the issue? In that, are each monitor connected to the own private LAN, so you can't access it from the 2-wire cable?
Which modules do I need (also with 3 dedicated buttons)?
Which are the disadvantages respect the direct IP one?
