ZKTeco G4L 4G Multi-Biometric Access Control and Attendance Terminal

Overview

The ZKTeco G4L is a door access and attendance terminal for workplaces with many staff, built on Android 9.0 with visible light face recognition. It can take power over the network cable (PoE) and, with the optional 4G module, report over a mobile network, so it suits offices, factories and remote gate houses where there is one cable or no fixed line at all. Faces, cards, QR codes and optional fingerprints are all read on the same unit.

Is it right for you?

• It suits a busy entrance: 50,000 users, 50,000 faces, 50,000 cards and 1,000,000 transactions cover a large workforce.
• It suits a position with only a network cable, since Power over Ethernet (PoE) to IEEE 802.3af/at powers it, or a remote gate with no wired network, using the optional 4G module.
• It suits a place that already issues 125 kHz or 13.56 MHz cards, as both are read as standard.
• It works from -20 to 55 °C, so it copes with unheated and hot positions. No ingress rating is stated, so treat exposed outdoor mounting with care.
• If you want fingerprints, order the optional Z-ID fingerprint sensor; it is not fitted as standard.

Key features

• Recognises a face in 0.5 seconds or less at 0.5 to 3 m, so staff walk up without stopping.
• Mask detection, plus anti-spoofing against print attacks (laser, colour and black and white photos) and video attacks, on the ZKFace 5.6.2 algorithm.
• 7-inch touch screen (720 × 1280) and a 2 MP binocular camera, driven by a 64-bit octa-core 1.8 GHz CPU with 2 GB RAM and 16 GB storage.
• Built-in QR code reader for dynamic codes from the ZKBio CVSecurity mobile app, which also reads PDF417, Data Matrix, MicroPDF417 and Aztec codes in third-party projects.
• Dual-frequency 125 kHz and 13.56 MHz card module as standard, with a multi-tech card module as an option.
• OSDP v2.1.7 over RS485 and Wiegand in and out, so it also works with other access control panels.
• On-board lock relay, exit button, alarm output, auxiliary input, door sensor and external bell terminals.
• Duress mode by password and fingerprint, anti-passback, access levels, groups, holidays, schedule bell and custom wallpaper. Certified to CE, FCC, ISO9001, ISO14001 and ISO20000.

What else you need

• Either a 12 V DC 3 A adapter or an 802.3af/at PoE switch port.
• An electric lock, an exit button and a door sensor (door position sensor), which are separate items.
• A SIM and a mobile network plan, only if you use the optional 4G module.
• The optional Z-ID fingerprint sensor (30,000 templates), only if you want fingerprint entry.
• The optional multi-tech card module, only if your cards are not standard 125 kHz ID or 13.56 MHz IC.

Installation

An access control installer should fit it. The terminal is 264 × 120 × 51 mm and wall mounts beside the door. The work covers the lock relay, exit button, door sensor, alarm and auxiliary wiring, a network cable or PoE port, and setting up the link to the software.

Software and licences

Works with ZKBio CVSecurity for access control and with easy TimePro on attendance firmware. Developers can build on it through the Android LCDP tool and the PUSH SDK. Dynamic QR codes are issued from the ZKBio CVSecurity mobile app.

Before you buy

• The 4G module, the multi-tech card module and the fingerprint sensor are options to confirm at order time.
• 4G bands vary by region, so tell us which mobile network the terminal will use.
• Fingerprint capacity (30,000) applies only with the optional sensor fitted.
• For a quote, tell us which options you need and the network the unit will run on.
