Scanner | Zkteco Ip

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 .

While the official ZKTeco scanner is reliable, there are situations where you need alternative methods.

To manage a ZKTeco device, it must be discoverable on your Local Area Network (LAN). Default IP Configuration

: Go to the Device tab and click Add .

Some high-end controllers stop responding to discovery broadcasts if configured for static server polling. zkteco ip scanner

Discover the current IP addresses of all connected ZKTeco hardware.

If your ZKTeco IP scanner returns zero results, run through this troubleshooting checklist:

If your ZKTeco device is on a private network behind a firewall (NAT), and you need to access it from the cloud, an IP scanner will only find the local address. To bridge this gap, administrators are increasingly using ngrok to create reverse TCP tunnels. By running ngrok tcp <Local_IP>:<Port> , you generate an external address (e.g., 8.tcp.ngrok.io:18274 ) that the cloud software can connect to, effectively scanning and connecting across the internet. The Windows Firewall often blocks incoming and outgoing

Before diving into scanning, it helps to understand what you are scanning for. ZKTeco's product line is vast, ranging from simple fingerprint readers like the and SLK20R models to advanced facial recognition systems like the SpeedFace-V5L TI and ProFace X . The company also manufactures complex access control panels such as the C3-100/200/400 series and video surveillance units.

: Provides real-time visibility into whether a terminal is online, its current firmware version, and its serial number for easier inventory.

| Feature | Description | |---------|-------------| | | Scans a user‑defined IP range or the entire local subnet for active ZKTeco devices. | | Device Information | Displays IP address, MAC address, device model, firmware version, serial number, and connection status. | | Mass Configuration | Allows simultaneous network settings changes (e.g., switching from DHCP to static IP) on multiple devices. | | One‑Click Access | Directly opens the device’s embedded web interface or launches the ZK BIOS tool for advanced settings. | | Export Reports | Saves detected device lists as CSV or text files for documentation or auditing. | | Cross‑Platform | Available for Windows (most common) and, in some versions, for Linux and macOS. | To manage a ZKTeco device, it must be

ZKTeco devices are usually connected via Ethernet cable to a network. However, they may come with a default IP address that does not match your current network subnet. The ZKTeco IP Scanner is a lightweight utility that acts as a "device locator," scanning the LAN to find any connected ZKTeco hardware regardless of its current IP configuration.

This is where a tool becomes indispensable.

: Includes "Scanner Logs" (S Logs) to track how many times a device has been triggered for verification, helping troubleshoot sensor issues. Common Default Credentials for Discovered Devices

Run the setup file and install the application on a computer connected to the same network as the device. 2. Connect Your Device

The package automatically handles the backend discovery process. It attempts a TCP connection first, falling back to UDP if needed. This is a powerful way to build custom dashboards for device management.
