How to Reset CCTV DVR & NVR Password: A Complete Guide

Locked out of your CCTV system after forgetting the NVR or DVR password? You're not alone—it happens more often than you'd think. The good news is that most systems offer built-in recovery methods, so you can typically restore access without swapping out hardware or calling in a professional.

This walkthrough covers several reliable CCTV password reset techniques: physical reset buttons, internal jumper points, manufacturer recovery utilities, and software-based approaches.

Safe Ways to Reset Your DVR or Recorder

Getting locked out of your DVR doesn't mean you're out of options. Depending on the model you own, your technical know-how, and the tools at hand, you can pick the approach that suits you best. Here are the most widely used and dependable methods.

If you're searching for how to reset DVR to factory default without password, the techniques below cover the most trustworthy ways to do it safely.

1. Try the Physical Reset Button (Where Available)

A large number of recorders include a concealed reset button or pinhole located on the rear, bottom, or side panel. This tends to be the fastest and simplest route back to factory defaults.

If your unit has one, follow these steps:

1. Make sure the recorder stays powered on.
2. Take a straightened paper clip, insert it into the pinhole or press the button, and hold it down for roughly 5–30 seconds.
3. Let go when you hear audible beeps or see the LED indicators flash. The device will reboot and present the initial setup wizard, where you can define a fresh password.

2. Access the Internal Reset Switch or Jumper

How to reset NVR without reset button is a frequent question from users whose recorder lacks an external reset control. In many units, there's still an internal tactile switch or a two-pin jumper on the mainboard—though reaching it typically means opening up the enclosure.

If you're comfortable removing the housing, here's the process:

2. Power down the recorder and disconnect it from the mains.
3. Open the casing with care, take off the top cover, and find the internal reset button or the two-pin header marked "RESET" or "CLR."
4. Power the unit back up while keeping the button pressed or bridging the pins with a screwdriver for about 30 seconds.
5. Release and let the recorder restart.

3. Attempt Default Login Details or a Master Password Generator

On older, unbranded H.264 DVRs—particularly those generic units with no identifiable make, commonly found in budget CCTV installations—you've got two standard routes back in when locked out. These approaches lean on either factory-default credentials or a date-driven master password.

3. Option 1: Default Login Credentials

A lot of legacy DVRs ship with preset username and password combinations that owners neglect to update. Occasionally, entering these details logs you straight in or triggers a reset sequence that asks for a new password.

Authorities such as CISA and the FBI strongly recommend changing all default passwords immediately after regaining access, since weak or factory-default credentials are a major target for cyberattacks against CCTV systems and IoT devices.

Username and password combinations worth trying:

• Password: 123456, 111111, 000000, 888888
• Password: 6036huanyuan, ttvvtthuanyuan (on certain models these may act as reset triggers)

Work through these combinations one by one and see whether the system either grants access or prompts you to set a new password.

4. Option 2: Master Password Generator

When the default credentials fail, many of these DVRs let you produce a one-off master password using the device's current date and time. In day-to-day use, this kind of utility often goes by the name DVR password reset tool, particularly for ageing generic hardware.

Quick steps:

5. At the login screen, snap a photo or jot down the displayed date and time.
6. On a separate computer, download and install a Master Password Generator utility (widely shared on technical forums and support sites).
7. Feed the date/time values into the generator and let it compute a master password.
8. Enter the generated password on the DVR login screen as admin to gain entry.
9. Once inside, create a secure new password without delay.

4. Obtain a Reset Code from the Manufacturer

Certain manufacturers can produce an unlock code from the recorder's serial number or MAC address:

6. Find the serial number/MAC address on the label affixed to the back of your recorder.
7. Reach out to the manufacturer's technical support and ask for a reset code.
8. Key in the supplied code on the login screen to unlock the device.
9. Set a new password straight away.

5. Factory Reset via the Web or Local GUI Session

If you're already signed in on a different device or browser tab, you can trigger a factory reset straight from the software interface.

Here's how:

7. Navigate to the system settings menu and head to Maintenance or System Management.
8. Choose Factory Reset and confirm the operation.
9. Wait for the recorder to reboot, then follow the setup wizard to create a new password.

6. Pull the CMOS Battery (Not Always Reliable)

On older hardware, removing the CMOS battery clears the BIOS, which might include login data. But on contemporary recorders, passwords tend to live in flash memory, so this approach isn't guaranteed.

If you still want to give it a shot:

8. Power off the recorder and unplug it.
9. Open the enclosure and gently take out the small coin-cell battery from the motherboard.
10. Leave it out for anywhere between 30 minutes and 24 hours.
11. Put the battery back, close the casing, and power the unit on.

Key Points to Consider Before Resetting

Before you carry out any reset, it's worth understanding what you stand to lose. A factory reset can get you back into your device—but it may also wipe important configurations or stored footage. Keep the following in mind before you begin.

• Recorded Footage May Be Erased: Some DVRs and NVRs delete all locally saved video during a reset. Others preserve recordings but remove account details, network preferences, or user settings. If you can, back up your footage beforehand, particularly if it's held on internal storage.
• Network Settings Will Be Wiped: Resetting usually clears custom network parameters such as static IP addresses, port forwarding rules, and Wi-Fi passwords. Make a note of your current settings so you can restore them quickly afterwards.
• Cameras Will Need Re-Pairing: A factory reset generally unlinks every connected Security Camera from your DVR or NVR. After the reset completes, you'll need to reconnect each camera individually. Depending on the system, this can be quick or fairly involved, so plan ahead.
• Firmware Might Offer a Simpler Fix: In some situations, a full reset may not be necessary. Issues like freezing, lag, or login failures can sometimes be traced to outdated firmware. Check whether a software update is available—updating the firmware can often sort out the problem while leaving your settings and recordings untouched.

FAQs

How to reset DVR password if forgotten?

If you've misplaced your DVR password, begin by checking whether your unit has a physical reset button or pinhole. With the DVR powered on, hold this for 5–30 seconds until you hear a beep or notice the lights flash—the system should then reboot and let you configure a new password. If there's no button, look for a password reset option in your device's GUI or get in touch with customer support. For generic H.264 DVRs, generating a one-time master password based on the on-screen date is another option.

What to do if you forgot your NVR admin password?

If you've forgotten your NVR admin password, start by checking for a physical reset button or pinhole that can return the unit to factory defaults. Many contemporary devices also support password recovery through an app or web portal, typically using email verification or QR code scanning. Another route is to contact the manufacturer directly, supplying the serial number, to request a one-time reset code.

What is the default password for NVR DVR?

Default passwords differ considerably by manufacturer and model. For older or unbranded hardware, common combinations include admin/admin, admin/123456, admin/12345, root/root, or user/user, along with simple strings such as 000000 or 888888. For branded equipment, check the manual or look for login information printed on the label or unit. Most recorders default to admin with a blank or straightforward numeric password.
