A 4.3-Inch Apartment Station for 20,000 Users

The VTO6521H is a multi-tenant apartment station with a 4.3-inch IPS display, touch button entry and capacity for 20,000 users and 10,000 cards. It supports SIP servers, which is what lets it work as part of a managed building platform rather than a standalone door.

Key Details

• 20,000 users, 10,000 cards — Building-scale capacity, administered centrally rather than per door.
• Full-duplex talk — Both parties can speak at once, like a phone call rather than a two-way radio. Half-duplex intercoms are a constant low-level irritation for residents.
• Duress and tamper alarms — Reports duress entry, tampering and a door left open past its timeout — the events that matter in a managed building.
• SIP server support — Registers to a SIP platform so calls can route to apps, desk phones or a concierge rather than only to fixed monitors.
• True WDR and auto illumination — A 2MP camera with true WDR and automatic lighting, rated IP65 and specified from −30°C to +60°C.

Where It Fits

For apartment buildings and multi-tenant sites needing a managed, auditable entrance. If the building needs a more vandal-resistant panel, the stainless VTO6521K is the same platform in 316 steel.
