Sure thing. Keep the unit solid – use a hardened chassis, sealed ports, and a battery that runs at least 24 hours. Add a manual override switch that works even if the power’s out. Put a basic two‑way voice lock so a hacker can’t hijack the line. Use a simple keypad with a one‑touch emergency code, and back it up with a local speaker that plays a clear alert when the system’s offline. That way the intercom stays a reliable, comforting voice even when the rest of the building is in chaos.
