The VIS-3020 is a kind of high-performance product, with a 32 bit high-speed processor. It communicates with access controller via the RS-485 protocol. And a built-in tamper-proof module helps to protect card reader from malicious damage. The protective level is IP65, which is suited for outdoor installation.
A group of messy code encrypted data for the security of fingerprint storage.
Supports RS485 communication with 19200bps-N-8-1 transmission rate. There are CRC test for the protocol.
Supports EM card reading.
Card induction distance is 0 mm to 100 mm.
Supports multiple authentication modes (card, fingerprint, and card + fingerprint).
Optical CMOS fingerprint module. The characters of fingerprint can be export to the card reader.
Max. 9500 fingerprints storage.
Communication circuit is designed with optical coupling isolation and noise suppression function.
Build-in buzzer for status indication
Accurate data and time display provided by built-in electronic clock and watchdog program to ensure the basic function of the terminal
