The Dahua VTO6521H is an advanced IP video intercom outdoor station, specifically designed for use in apartment complexes. It features a 2MP HD color camera, a 4.3-inch IPS display, an illuminated numeric keypad, and an integrated Mifare card reader. The VTO6521H uses Dahua's proprietary SIP protocol firmware and connects via a network cable (LAN) and a separate power supply (12VDC/2A, not included).
Possibilities
Thanks to its wide 113.79-degree horizontal field of view and infrared night vision, the camera provides clear images, even in low light. The outdoor station supports audio and video calls via an indoor monitor, the free Dahua app (iOS/Android), or SmartPSS software for Windows. If no one answers, visitors can leave an audio/video message, provided a microSD card is inserted in the indoor monitor.
The keypad allows you to easily call an apartment, while doors can be opened with a Mifare card, PIN code, an indoor monitor, an app, or SmartPSS software. Images can be continuously recorded to an NVR or NAS.
Assembly
The VTO6521H is suitable for both flush-mounting (with VTM121) and surface-mounting (with VTM130). Enclosures, power supplies, and Mifare cards are available as options.
