XMEye App QR Code (Primary Method)If your device supports the XMEye cloud platform, you can often reset the password by clicking the QR code icon next to the password input field on the login screen. Scan this code with the XMEye app to receive a temporary unlock code or to prompt a system reset.

Physical Jumper Bridge (Advanced)For older boards or those without QR code support, you can perform a hardware reset:

Locate the "JPW" or similar jumper pins on the motherboard (often near the SATA connectors). If you have network access to the router

Use a metal tool to bridge Pin 1 and Pin 2 while the device is powered off.

Hold the bridge and power on the device. Wait for a single beep (approx. 5–7 seconds) before releasing the short.

CMOS Battery RemovalDisconnect power and remove the coin-sized CMOS battery from the motherboard for at least 30 seconds. This can sometimes revert the system clock and settings to a state where default passwords work.

Use the "Forgot Password" or QR Code Feature

Modern firmware often includes a self-service recovery option on the login screen:

Click the "Forgot Password" or question mark icon on the login interface.

If a QR Code appears, scan it using the manufacturer's mobile app (often XMeye, vMEye, or CCTV Viewer). This will usually send a temporary security code to your registered email. 3. Generate a Super Password (Serial Number Method) you can use physical hardware overrides

If the defaults fail, you can generate a one-day master code based on the system date or serial number:

Locate the Serial Number: Look for a sticker on the bottom of the unit or find it in the "Info" section of the login screen.

Check the System Date: Note the date currently displayed on the DVR's monitor (e.g., 2026-04-26).

Use a Super Password Generator: Many independent CCTV Support Sites provide tools where you input the date/serial to get a temporary code.

Contact Support: If you cannot find a generator, Eufy's Guide suggests contacting the manufacturer's technical support with your serial number to request a reset code. 4. Hard Reset (Hardware Method)

If you cannot access the software interface, you may need to open the casing:

Reset Button: Look for a small "Reset" button on the motherboard. Hold it for 15 seconds while powering the unit on.

CMOS Battery: Remove the silver coin-cell battery (CR2032) for 2–5 minutes and unplug the power. This can sometimes reset the clock to a default date (like 2000-01-01), allowing you to use a known "Super Password" for that specific date.
