GeoVision - 84-AS21200-0010 - IP Control Panel
Product Overview
The GV-AS2120 is a versatile IP access controller for doors, gates, and elevators. It manages up to 4 doors one-way, 2 doors two-way (Wiegand), or 4 doors two-way (Wiegand/RS-485/Network). The panel supports 4 Wiegand readers (26–64 bits), 8 GV-Readers/fingerprint scanners, 8 digital inputs, and 8 relays (3A) with an onboard tampering alarm. It features dual-power options via DC12V, 3A, or PoE+ (802.3at).
Key Configuration
- • Doors: one-way control (4 doors); two-way control (2 doors by Wiegand only, or 4 doors by Wiegand/RS-485/network)
- • Reader interfaces: 4 Wiegand readers (26–64 bits); 8 GV-Readers/GV-GF Fingerprint Readers via RS-485/network
- • I/O: 8 inputs (dry contact, NO/NC); 8 relay outputs (30V DC, 3A; 110–250V AC, 3A)
- • Capacity: 100,000 user cards; 1,000,000 event buffer
- • Dimensions: 210 × 204 × 46.6 mm (8.27" × 8.03" × 1.83") with case; weight: 810 g (1.79 lb)
Key Features
Driven by a 32-bit ARM7 CPU, this network-ready controller utilizes TCP/IP communication and requires GV-ASManager V4.3 or later. For reader integration, it features one RS-485 interface (up to 8 GV/fingerprint readers up to 600m), four Wiegand ports (26–64 bit, up to 100m, providing 12V DC/200mA), and one dedicated network reader interface. The board includes a tampering alarm, a replaceable button cell backup battery, and carries CE, FCC, and RoHS certifications.
Technical Context
It features dual-power capability, accepting either direct network power via built-in PoE+ (IEEE 802.3at), supplying up to 25.5W, or local power through an external DC12V, 3A adapter.
Installation Notes
This controller measures 210 × 204 × 46.6 mm and weighs 810 g. It operates efficiently in environments from 0°C to 65°C with 10–90% non-condensing humidity. The unit offers flexible power options, supporting either PoE+ (IEEE 802.3at, 25.5W) or an external DC12V, 3A adapter (not included). For peripheral deployment, it supports long-range wiring distances up to 600 m for RS-485 interfaces and up to 100 m for Wiegand connections.
