ZKTeco C3 Plus Series IP-Based Access Control Panel (1/2/4 Door)

Overview

The ZKTeco C3 Plus series is a network door controller for small and medium businesses that lets people in by card, password or QR code at one, two or four doors. The board sits in a cupboard or riser, the readers sit at the doors, and everything is set up through a built-in web server or ZKBio CVSecurity. Typical uses are office floors, server rooms and shared building entrances wired back to a network switch. The range covers the C3-100 Plus (1 door), C3-200 Plus (2 doors) and C3-400 Plus (4 doors), which share the same Linux platform and differ in door and reader count.

Is it right for you?

• It suits card and QR code access: there is no biometric option on this panel. For face or fingerprint at the door, the InBio Pro Plus series is the biometric equivalent.
• Choose 1, 2 or 4 doors so the panel matches the real door count; several panels can be mixed across a building.
• It works with ZKTeco RS-485 and OSDP readers and with third-party Wiegand readers, so existing readers can often stay in place.
• It is for indoor use, 0 to 45 °C, in a secure location.

Key features

• Verifies by card, password or QR code, with capacity for 100,000 cards and 100,000 static or dynamic QR codes.
• Holds 100,000 users and 500,000 transactions as standard.
• Reader connections: C3-100 Plus takes 2 RS-485 readers and 2 Wiegand readers; C3-200 Plus 4 and 4; C3-400 Plus 8 RS-485 and 4 Wiegand. RS-485 readers use ZKTeco RS-485 or OSDP (Open Supervised Device Protocol) version 2.1.7, and the QR50, QR500 and QR600 QR code readers are supported.
• Wiegand input accepts 26, 34 and 66-bit cards, so third-party readers can be kept.
• Per door: a lock relay, a door sensor input, an exit button input, an alarm output, an auxiliary input and an auxiliary output (Form C relays).
• Up to eight EX0808 I/O expansion boards over RS-485 take it to 64 inputs and 64 outputs.
• AES 256-bit storage encryption, AES 128-bit encryption between the controller, readers and expansion boards, and HTTPS with TLS 1.2 to the web client.
• Built-in web server, 14-digit user IDs, access levels and groups, holidays, anti-passback, anti-tailgating, linkage and global linkage.

What else you need

A 12 V DC supply (the board accepts 9.6 to 14.4 V DC); readers for each door; an electric lock, exit button and door sensor per door; and a network connection. The optional metal enclosure in SPCC steel (350 x 90 x 300 mm) includes a 110 to 240 V AC power supply unit with 12 V 4 A plus 1 A DC output and space for a backup battery (recommended size 151 x 94 x 65 mm). Only if you use dynamic QR codes, you also need ZKBio CVSecurity and its mobile app.

Installation

An access control installer should fit it. The job involves mounting the board on a wall or in the enclosure, wiring readers (RS-485 or Wiegand), locks, exit buttons and door sensors to each door, connecting the 12 V DC supply and the network, then configuring doors, access levels and users through the web server or ZKBio CVSecurity. Board sizes are 175 x 99 x 19.3 mm (C3-100 Plus and C3-200 Plus) and 215.88 x 99.14 x 19.3 mm (C3-400 Plus).

Software and licences

Standalone set-up through the built-in web server over HTTPS. ZKBio CVSecurity manages it with the rest of a ZKTeco system, including access control push from the firmware and dynamic QR codes issued through its mobile app. A USB Type A port takes a USB drive only.

Before you buy

• The panel ships as a board; the metal enclosure with its 110 to 240 V AC power supply unit and backup battery space is an option.
• Tell us your door count, reader type and whether you need the enclosure so we can quote the right model.
• No biometric readers: for face or fingerprint, choose the InBio Pro Plus series.
