Overview

The Realtime RS20 Plus records attendance and controls one door with fingerprint, card or PIN. It suits larger offices, factories and schools.

Is it right for you?

Choose it if you need fingerprint, card or PIN sign-in for up to 5,000 people and storage for 100,000 attendance records. It works offline and also connects by network cable or Wi-Fi for live reports. For touch-free sign-in, look at a face recognition terminal instead.

Key features

  • Separate capacities: 5,000 fingerprints, 5,000 cards, 5,000 PIN users, 100,000 attendance records
  • 3 inch colour display
  • Connects by Ethernet (TCP/IP), Wi-Fi and USB drive, with optional 4G/5G
  • Built-in backup battery keeps it running through short power cuts
  • Lock relay output for one door with Wiegand output to an access controller
  • Cloud connectivity for attendance reports

What else you need

  • RFID cards or key tags for card users
  • For door control: an electric lock (EM lock, electric strike or drop bolt), an exit button and a 12 V DC access control power supply for the lock
  • A network cable point or Wi-Fi where it is mounted, if you want live reports

Installation

Mount it on the wall at the entrance where people sign in, near a power point. Door control needs wiring to the lock, exit button and power supply, which is a job for an installer.

Software and licences

Realtime offers free Windows attendance software (Realsoft and Attendance Tracker) and cloud attendance portals (Onlinerealsoft, paid, and Staff Khata, with a free attendance plan) for its terminals; the links are under documents on this page. Ask our team which one suits your setup before you order.
