A22
The A22 is ATRIUM’s powerful Web-Based IP hybrid module. The flexibility of the A22 module allows it to be set either as a 2-door controller or expander (2 in 1).
The A22 includes an embedded web server that combines performance and simplicity enabling you to manage Users/Cards, lock or unlock doors, view system events and display controller information from anywhere in the world! Industry-unique and effortless card enrolment mode minimizes system start up and simplifies your life. A pre-assembled universal power supply is included with every A22, making this unit an industry leader in efficiency and simplicity. Web-Based IP Controller
