Hey Product Hunt! 👋 I'm Seçkin, co-founder of MobilDiafon. If you've ever lived in an apartment, you know the intercom — that little box by the door that hasn't changed in decades. Wiring, panels, constant breakdowns, a technician on speed dial. Everything else went digital… so why not this? MobilDiafon turns any smartphone into the building's intercom. A visitor scans a QR code at the door (or finds the building by location), video-calls the resident, and the door opens remotely — no wiring, no hardware per apartment, set up in minutes. It brings building managers, security, and residents into one platform, works with Shelly smart locks, and even has an "Auto" product that verifies vehicle entry by QR. We're building from Istanbul & Brussels and would love your feedback — especially on where digital building access should go next. What would make you trust (or not trust) a phone-based door system? 🙏
