If you are locked out of your H.264 DVR, the first step is to try common default credentials, as many generic systems use standard factory settings. 1. Common Default Credentials
Most H.264 DVRs use "admin" as the username. Try the following password combinations: Username: admin | Password: (Leave blank) Username: admin | Password: 123456 Username: admin | Password: 888888 Username: admin | Password: 000000 or 111111 Username: admin | Password: admin 2. Alternative Login Methods
Pattern Unlock: Some systems use a graphical pattern instead of a text password. A common default is a backwards "C" (starting from the top left, dragging to the top right, down the right side, and then across to the bottom left).
QR Code Reset: Modern units often display a QR code on the login screen. You can scan this using the manufacturer's app (like Hik-Connect) to receive a temporary reset code via email. 3. Physical Hardware Reset
If software defaults fail, you may need to manually reset the device to factory settings:
Internal Reset Button: Power down the unit, open the casing, and look for a small button on the PCB (Printed Circuit Board) labeled "Reset." Press and hold it for several seconds while powering the device back on.
Battery Removal: Removing the CMOS battery (small silver coin cell) from the motherboard for 2–5 minutes can sometimes reset the internal clock and system settings, potentially reverting the password to the factory default or allowing a "super password" bypass based on the date.
Remote Control Method: For certain models, you can hold any button on the infrared remote while powering on the unit until you hear a series of beeps to trigger a factory reset. 4. Super Passwords by Date
Many generic H.264 DVRs (often using Xiongmai/XMeye firmware) use "Super Passwords" that change daily. You can find "DVR Password Generators" online or in app stores that calculate a bypass code based on the current date shown on your DVR's monitor.
Safety Tip: Once you regain access, immediately navigate to Setup > Advanced > Account (or similar) to set a new, secure password. To help you find the exact reset method, could you tell me: The brand or model name on the front of the DVR? The date and time currently displayed on your monitor? How to Log Into Your DVR
Before diving into passwords, it helps to understand the hardware. An H.264 DVR converts analog camera footage into a digital format using the H.264 compression standard. Unlike modern H.265 or cloud-based IP systems, these DVRs typically run on a proprietary Linux-based operating system from manufacturers like Hikvision, Dahua, Zosi, Annke, and Lorex. Admin : 12345, admin, or password Username :
The login password is the gateway to:
If you lose or forget this password, your security system becomes a brick.
Most H.264 DVRs from common brands (e.g., Hikvision, Dahua, Zmodo, Annke, Q-See) ship with default credentials:
| Field | Default Value |
|-------|----------------|
| Username | admin |
| Password | admin / 12345 / (blank) / password |
Note: Some newer models force password creation during first-time setup.
Unlikely. If the DVR boots but rejects all passwords, the firmware may be corrupted, or the password was set via a remote CMS (Central Management System). Try these last steps:
As a last resort, reflash the firmware (requires a USB drive and firmware from the manufacturer). This will wipe everything, including the password.
Once you have regained access to your H.264 DVR, do not leave the password as default. Default credentials are public knowledge, and leaving them unchanged is an open invitation for hackers to view your cameras remotely.
| Action | Why |
|--------|-----|
| Change default admin password immediately | Prevents basic takeover |
| Use a strong 8+ char password (if firmware allows) | Resists brute force |
| Disable remote access (UPnP / port forwarding) unless needed | Reduces internet exposure |
| Write down password in a secure place (e.g., password manager) | Avoids factory reset |
| Update firmware if available | Fixes known backdoors |
| Consider upgrading if DVR lacks password lockout | Protects against online brute force attacks |
Previous owner changed the password. You need a factory reset (see Section 5).
