View or edit the assigned IP address, Subnet Mask, and Gateway.
When scanning and subsequently connecting to the device, ensure your data is protected. Most modern ZKTeco devices support HTTPS configurations (port 1443) for web encryption. However, the primary attendance data stream (port 4370) often relies on legacy TCP protocols. If your network spans multiple buildings or connects via the internet (using ngrok or port forwarding), this data should be encrypted via a Virtual Private Network (VPN) rather than exposed directly to the internet.
Verify that the Link LED light on the ZKTeco network port is illuminated green or amber. If dark, replace the network patch cable or check your switch port. zkteco ip scanner
The Windows Firewall often blocks incoming and outgoing discovery packets. Temporarily disable your firewall or add an exception for your ZK software and UDP port 4370 .
Identifying these devices allows administrators to open the web management interface, modify IP configurations, update firmware, and link hardware to centralized management software. Primary Tools for Finding ZKTeco Devices View or edit the assigned IP address, Subnet
Standard tools like ping or nmap check if a device is online via ICMP. Many ZKTeco devices disable ICMP ping responses for security or power saving. The ZKTeco scanner uses the SDK handshake protocol; if the device has the ZK biometric server running (even with ping disabled), the scanner will find it.
Ensure your ZKTeco device is connected via Ethernet cable to the same switch/router as your computer. However, the primary attendance data stream (port 4370)
Centralized software suites like , ZKBioSecurity , or ZKBio Time feature built-in device discovery tools.
Windows Firewall or antivirus software may block the scanning tool. Add an exception for the tool or temporarily disable the firewall.
While the official scanner is excellent for discovery, advanced users or integrators managing 50+ devices may need more features.
For those who have invested in the full ZKTeco security suite, the scanning functionality is built into the management platform. In and ZKBioAccess MTD software, the process is menu-driven:
