Other User Interface Descriptions¶

Wi-Fi & IP Interface¶

The first screen displayed in the Panda Alarm Web UI is the Wi-Fi & IP settings page.

① Enter the Wi-Fi & IP interface
② To reconfigure the Wi-Fi connection for Panda Alarm, click the Wi-Fi Network Configuration button to return to the Wi-Fi configuration screen.

Tip: When Panda Alarm switches to a different Wi-Fi network, its local network and IP address may change. If you change this setting on a device within the same network, communication with Panda Alarm will be lost. The device will need to reconnect to the newly configured Wi-Fi. To avoid this, we recommend connecting your device to Panda Alarm’s AP hotspot first, then changing the configuration.
③ Once the network configuration is complete, we recommend connecting your phone, computer, or other devices to the same Wi-Fi network as Panda Alarm. Access the Web UI via the IP address in your browser’s address bar. You can also save the IP address as a bookmark on your home screen for easy access.
④ If your device is on the same network as Panda Alarm, you can access the Web UI using the hostname. The default hostname PandaAlarm, accessible at http://pandaalarm.local (case-insensitive). If your device is using a VPN, this method may not work, and you should use the IP address instead.

Users can customize the hostname by following these rules:
- It must consist of letters (a-z, A-Z), numbers (0-9), and hyphens (-), with the first character being a letter.
- It must be between 8 and 32 characters long.
After changing, click Set Hostname to apply the new hostname to Panda Alarm. If a pop-up window appears, the hostname has been successfully updated. The new hostname will take effect after a reboot. Click OK to reboot Panda Alarm immediately, or click the x button to close the window without rebooting.

AP Interface¶

The next screen in the Panda Alarm Web UI is the AP interface. The Panda Alarm AP is the Wi-Fi hotspot broadcast by the device, allowing a phone or computer to connect directly. If you do not want the hotspot to be broadcast, you can disable it. However, Panda Alarm will automatically re-enable the hotspot if it cannot connect to the configured Wi-Fi. This ensures a fail-safe method to reconnect if the configured Wi-Fi is unavailable.

Tip: If your device is connected to the Web UI through the Panda Alarm AP hotspot, disabling or changing the AP settings will disconnect your device. To avoid this, connect your device to the same Wi-Fi network as Panda Alarm before making any changes.

① Enter the AP interface.
② Enable/disable the Panda Alarm AP hotspot. Once disabled, you will no longer be able to connect to Panda Alarm through its hotspot. Before disabling, make sure to note the Panda Alarm IP address on the current Wi-Fi so you can still access the Web UI via IP.
③ Edit the Panda Alarm AP hotspot settings. The default configuration is:

Wi-Fi Name: Panda_Alarm_xxxxxxxxxxxx

Wi-Fi Password: 987654321

After ch~anges, no reboot is required—the device will recreate the AP hotspot in the background.
④ Change the AP hotspot IP address. If the IP range conflicts with your router (for example, if both use 192.168.254.1), Panda Alarm will be unable to bind to the printer. To resolve this, change the Hotspot IP to a different range, such as 192.168.253.1.

After modifying the Hotspot IP, you must reboot the device for the new settings to take effect. If the following pop-up appears, the Hotspot IP has been successfully updated. Click OK to reboot Panda Alarm immediately, or click the x in the upper-right corner to close the pop-up without rebooting.Wi-Fi密码: 987654321

Settings¶

① Enter the Settings interface
② Choose the language for the Web UI
③ Device sound effect audio files data. Use this method to rewrite the factory default audio files only if the pre-installed audio files are corrupted. Note: Updating the .img file will overwrite the User Custom Voice.
④ Firmware information of the device
⑤ Restore Factory Settings

Restore Factory Settings¶

Restoring Panda Alarm to factory settings will erase all configurations, including language, connected Wi-Fi, custom hostname, custom AP hotspot name and password, bound printers, light effects, sound effects, and other settings. However, the User Custom Voice will be retained.

Restore Factory Settings via Web UI¶

Enter ① the Settings interface, and click ② the Restore Factory Settings button.
A confirmation pop-up will appear. Click ③ Yes to confirm the restoration of factory settings, and Panda Alarm will restore to factory settings and reboot.

Restore Factory Settings via Button¶

Use a sharp object to press and hold the Recovery button for 5 seconds, and Panda Alarm will restore factory settings and reboot.
