Misplaced your NVR or DVR password and locked out of your CCTV? It’s a common slip-up—but easy to fix without needing to replace gear or hire a pro. Most CCTV devices have a hidden reset button that lets you restore access quickly.
In this guide, you’ll learn exactly how to reset NVR and DVR without password using physical buttons, internal reset points, software tools, and more.
1. Use the Physical Reset Button (If Available)
Many recorders have a hidden reset button or pinhole on the back, underside, or side panel. This is the quickest and easiest way to restore factory settings.
If you find one on your device, follow these steps:
- Keep the recorder powered on.
- Insert a straightened paper clip into the pinhole or press the reset button and hold it down for about 5–30 seconds.
- Release when you hear beeps or see LED lights flashing. The unit then reboots and launches the first-run wizard where you can create a new password.
2. Use the Internal Reset Switch or Jumper
If your recorder doesn’t have an external reset button, there’s often an internal tactile reset switch or two-pin jumper on the main circuit board. This requires opening the device housing.
If you’re fine with opening the housing, here’s how to reset:
- Turn off the recorder and unplug it.
- Open the device casing carefully, remove the top cover, and locate the internal reset button or two-pin header marked “RESET” or “CLR.”
- Power the unit back on while holding the button or shorting the pins with a screwdriver for 30 seconds.
- Let go and allow the recorder to restart.
3. Try Default Login Credentials or a Master Password Generator
On older, unbranded H.264 DVRs—especially those generic models with no clear make used in budget CCTV setups—there are two common ways to regain access if you’re locked out. These methods rely on either default login details or a date-based master password.
Option 1: Default Login Credentials
Many legacy DVRs ship with preset usernames and passwords that users often forget to change. In some cases, entering these credentials will log you in directly or trigger the system to reset and prompt for a new password.
Common username and password combinations to try:
- Username: admin
Password: 123456, 111111, 000000, 888888
- Username: admin
Password: 6036huanyuan, ttvvtthuanyuan (these may work as reset triggers on some models)
Try these combinations one at a time and see if the system either logs in or asks you to create a new password.
Option 2: Master Password Generator
If the default credentials don’t work, many of these DVRs allow you to generate a one-time master password based on the current date and time stamp.
Quick steps:
- On the login screen, take a photo or write down the date and time displayed.
- On a separate computer, download and install a Master Password Generator tool (commonly provided on technical forums or support sites).
- Enter the date/time information into the generator and let it calculate a master password.
- Input the generated password on the DVR login screen as adminto gain access.
- Once logged in, set a secure new password immediately.
4. Request a Reset Code from the Manufacturer
Some manufacturers can create an unlock code from the recorder’s serial number or MAC address:
- Locate the serial number/MAC address on the sticker at the back of your recorder.
- Contact the manufacturer’s technical support and request a reset code.
- Enter the code provided on the login screen to unlock the system.
- Set a new password right away.
5. Factory Reset from the Web or Local GUI Session
If you’re still logged in on another device or browser tab, you can perform a factory reset from the software interface.
Here’s how:
- Open the system settings menu and go to Maintenance or System Management.
- Select Factory Reset and confirm the action.
- Allow the recorder to reboot and follow the setup wizard to set a new password.
6. Remove the CMOS Battery (Not Always Effective)
On older models, removing the CMOS battery resets the BIOS, which may include login details. But on modern recorders, passwords are often stored in flash memory, so this method doesn’t always work.
If you decide to try this, here’s how:
- Turn off and unplug the recorder.
- Open the housing and carefully remove the small coin-cell battery from the board.
- Leave it out for 30 minutes to 24 hours.
- Reinsert the battery, close the casing, and power the unit back on.
Important Considerations Before Resetting
Before performing any reset, it’s crucial to understand the potential impacts. A factory reset can help you regain access to your device—but it can also lead to loss of important configurations or data. Here are a few things to keep in mind before starting.
You May Lose Stored Recordings
Some DVRs and NVRs erase all locally stored footage during a reset. Others may retain video files but delete account information, network settings, or user preferences. If possible, back up your recordings in advance, especially if they’re stored on internal memory.
Network Settings Will Be Erased
Resetting your device usually removes custom network configurations like static IP addresses, port forwarding rules, and Wi-Fi credentials. This means you’ll have to reconfigure everything manually once the reset is complete. Be sure to jot down any current settings so you can restore them quickly.
Cameras Need to Be Re-Paired
A factory reset typically unlinks all connected cameras from your DVR or NVR. Once the reset is done, you’ll need to reconnect each camera manually. Depending on the system, this can be a simple or time-consuming task, so plan accordingly.
Firmware May Offer a Better Solution
In some cases, your issue might not require a full reset. Problems like freezing, lag, or login errors could be caused by outdated firmware. Before resetting, check whether a software update is available. Updating the firmware can often resolve the problem while keeping your settings and footage intact.
Thinking about an Upgrade? Check out NVR Setups from eufy
If your current DVR or NVR is an older, unbranded model that’s starting to freeze, lag, or throw up constant errors, it might be time to consider an upgrade. Outdated systems not only struggle with reliability but can also pose serious security risks due to weak default passwords and a lack of firmware updates.
A modern network video recorder system not only gives you the power of wired PoE cameras for rock-solid connections and 24/7 recording, but also offers intuitive and comprehensive app controls, smart AI features, and robot cyber-security.
The eufy NVR Security System S4 Max is a solid option here. Pairing the eufy 16 MP PoE Cam S4 units and the NVR S4, the system runs AI detection locally and allows you to build a future-proof setup that grows with your needs.
Standout Features of the S4 Max
- 16 MP Triple-Lens Cameras with 360° PTZ: Each eufy PoE Cam S4 unit combines dual 2K lenses for full 360° panoramic coverage and a 4K bullet lens on top for pin-sharp details. With 8× hybrid zoom and pan/tilt/zoom control, you can cover every corner of your property without blind spots.
- Local AI for Smarter Alerts: A built-in AI chip inside the NVR S4 detects people, vehicles, and pets directly on the device. No need to send video to the cloud—your data stays on-site and private.
- Live Cross-Cam Tracking: All cameras work together to track movement across your property in real time. When one camera reaches its viewing limit, another picks up instantly, ensuring uninterrupted coverage and smooth transitions.
- Colour Night Vision: Thanks to Starlight sensors and integrated spotlights, the system delivers clear, full-colour footage even in complete darkness.
- Expandable Storage and Channels: With eight built-in PoE ports and a 2TB hard drive, you can connect multiple cameras straight away. Need more? Add a PoE switch to support up to 16 channels and expand storage to 16 TB for months of continuous recording.
- Smart Video Keywords Search: Quickly find specific events by filtering recordings for “person”, “vehicle”, or “dog” rather than scrubbing through hours of footage.
Build a Hybrid System with Wired and Wireless Cameras
What really sets the eufy NVR S4 apart is its flexibility. It’s not limited to PoE cameras—you can also integrate eufy’s wireless cameras using two optional modules releasing in September:
- Wi-Fi Module: Connects the NVR to eufy Wi-Fi cameras, allowing them to share the same AI features and local storage.
- Long-Range Module: Extends Wi-Fi coverage up to 1.25 miles, making it easy to secure outbuildings, gates, or other hard-to-reach areas without running cables.
This means you can create a single, unified system that combines the reliability of wired cameras with the convenience of wireless where it makes sense.
Here are two solar-powered eufy outdoor Wi-Fi cameras to add on:
The 4K UHD eufyCam S330 combines an ultra-wide f/1.4 aperture and advanced night vision for sharp, colourful video even in low light. It comes with a built-in solar panel, so once installed, you won’t need to worry about charging.
