Losing a video surveillance system password is a common and extremely frustrating situation faced by both home camera owners and system integrators. When a device stops responding to traditional login credentials, access to live video and archived recordings becomes impossible, jeopardizing the security of the facility. In most cases, this isn't a case of hacking someone else's system, but rather of restoring administrator rights to one's own equipment, whether it was installed long ago or has been acquired by a new owner.
Modern IP cameras DVRs and video recorders have a sophisticated security structure that prevents unauthorized access by intruders. However, this same security becomes a barrier to legitimate users if login credentials are lost. Several proven methods exist for bypassing or resetting forgotten settings, restoring the device to working order. It's important to understand that restoring access requires physical contact with the device or access to the local network where it's located.
In this guide, we'll cover detailed procedures for various types of equipment, from budget Chinese models to professional security systems. We'll cover software and hardware reset methods, the use of specialized software to scan for configuration vulnerabilities, and standard factory reset codes. Please remember that the methods described below are only applicable to restoring access to your personal devices or equipment for which you have official permission from the owner.
Finding factory default credentials and passwords
The first and simplest step, often overlooked in haste, is checking the manufacturer's default settings. Many users either don't change the factory password when first installing the camera, or change it but then forget it, relying on the browser's auto-save feature. Knowing the device model allows you to select the default login and password combination, which often remains unchanged if the device hasn't been manually configured before.
To find the necessary information, you'll need to find the exact camera model, which is usually indicated on a sticker on the device's body or packaging. Once you know the model, you can consult the documentation or specialized databases that contain information. default passwords For thousands of devices. Manufacturers often use predictable combinations such as "admin/admin," "admin/12345," or an empty password for the "admin" login.
Below is a table of the most common factory credentials for popular brands of video surveillance systems. Please note that new firmware versions from some manufacturers require a password change upon initial startup, so this method may not work on recently released models.
| Brand / Manufacturer | Default login | Default password | Note |
|---|---|---|---|
| Hikvision | admin | 12345 | New models require activation |
| Dahua | admin | admin | Often used in older firmware |
| TP-Link Tapo | admin | admin | Account linking required |
| Reolink | admin | (empty) | The password is often not set initially. |
| Generic (China) | admin | 123456 | Universal combination |
If the default combinations don't work, it means the password has been changed by a previous user. In this case, you'll need to resort to more complex recovery methods, including a hard reset. Avoid brute-force password attempts over the network, as modern cameras block IP addresses after several unsuccessful login attempts.
Where else to look for passwords?
The password can be written on a sticker under the camera's battery or on the bottom of the box. Sometimes installers leave their business cards with the password written on the recorder or router itself.
Hard reset using the Reset button
The most effective and universal way to regain access to the camera is to perform a full factory reset (hard reset). This process erases all user configurations, including network settings, changed passwords, and recording schedules, returning the device to its out-of-the-box state. This method requires physical access to the camera body.
On most models, the reset button is located directly on the circuit board inside the housing or exposed through a small hole. In some outdoor cameras, the button may be located inside the SD memory card slot, requiring the card to be removed to access the reset mechanism. This typically involves holding the button for 10-30 seconds while powering on the device.
⚠️ Attention: After the reset, the camera's IP address will return to the factory default (often 192.168.1.10 or 192.168.0.10). You'll need to change your computer's IP address so it's on the same subnet or use special utilities to find the device on the network.
It's important to follow the reset sequence, as the process may vary on different devices. Some models require you to hold the button before connecting the power supply, while others do so after. If the reset doesn't work the first time, try varying the amount of time you hold the button or the moment you connect the power supply.
☑️ Hard reset algorithm
Using Onvif Device Manager to restore
If physical access to the reset button is difficult or impossible (for example, the camera is mounted high on a mast), software methods can be tried. Protocol ONVIF (Open Network Video Interface Forum) is a standard for IP security systems and often allows device management even if the manufacturer's web interface password is lost. The Onvif Device Manager (ODM) utility is a free tool that scans the network and displays all compatible cameras.
Sometimes, users change the password only for the web interface, forgetting to update the ONVIF user, or leaving the default "onvif" user with the factory password. By running the ODM program on a computer connected to the same network as the camera, you can see a list of devices. If you're lucky, you'll be able to log in to the camera automatically or using the default credentials.
The Onvif Device Manager interface not only lets you view the video stream but also change network settings or reset the password if the camera has a corresponding vulnerability or feature. The "Profiles" or "Snapshot" menus often conceal options for visually interacting with the device. This is a powerful tool for diagnostics and initial setup of equipment.
Restoring access via cloud services and QR codes
Modern IP cameras increasingly operate using P2P technology, eliminating the need for complex router port configuration. Access is provided through the manufacturer's cloud service using a unique QR code or UID number. If you've forgotten the password for the local interface but the camera is linked to your mobile app account, you can reset the settings remotely.
Open the app on your smartphone (e.g., Tuya Smart, Tapo, Mi Home), find your camera in the list of devices, and go to Settings. There's usually an option to "Delete device" or "Reset settings." After deleting a camera from your account, it often resets the local password or allows you to set a new one when you re-link it. This is the easiest method for home devices.
However, if the camera was linked to another person's account (the previous owner), you will need their participation to unlink the device. Without this step, the camera may remain locked by the "Device Binding" feature, which prevents it from connecting to another account even after a physical reset. This is a security measure to protect against equipment theft.
Specifics of resetting passwords on Hikvision and Dahua recorders
Professional video surveillance systems from brands Hikvision And Dahua These cameras have a more sophisticated security system than simple Wi-Fi cameras. Since 2016-2017, these devices have had an active security system installed that requires a password upon initial activation. You can't simply reset the password with a button on newer models—authentication is required.
To restore access, use an export file or XML file generated by the device itself. This file must be sent to the manufacturer's technical support or imported into a dedicated utility (for example, SADP Tool for Hikvision). After processing the file on the manufacturer's server, you will receive a key file that unlocks the device.
There's also a recovery method using security questions, if you set them during activation. If you've forgotten the answers to these questions, your only option is to contact technical support and provide the serial number and proof of purchase. Some older models allow you to reset the password by shorting the contacts on the board (EEPROM), but this requires soldering skills and carries the risk of damaging the electronics.
⚠️ Attention: The SADP Tool and ConfigTool interfaces are constantly updated. The algorithm for obtaining a reset file may be changed by the manufacturer at any time. Always check the latest instructions on the manufacturer's official website before beginning the procedure.
Finding the camera's IP address on a local network
Before attempting to connect to the camera, you need to find it on the network. After a factory reset, the camera receives a factory IP address, which may not match your local network's address range. For example, the camera may have an address of 192.168.1.10, but your router distributes addresses from the 192.168.0.x network. In this case, a direct connection is impossible without changing the subnet.
To find the device, use network scanners such as Advanced IP Scanner or Angry IP Scanner. These programs will quickly scan the entire address range and list all active devices, displaying their MAC addresses and manufacturers. By finding a device with a vendor that matches your camera, you can determine its current IP address.
If the camera is found but has an address on a different subnet, you need to temporarily change the IP address of your computer's network card. Go to the TCP/IPv4 protocol properties and enter a static address, for example, 192.168.1.100 with a mask of 255.255.255.0. You can then open the camera's web interface using its address and reconfigure it to work on your network.
Frequently Asked Questions (FAQ)
Can I connect to a Wi-Fi camera if I don't know the Wi-Fi network password?
No, you need to know the wireless network password to use the camera via Wi-Fi. However, if the camera has a LAN port, you can connect it directly to the router with a cable, set up data transfer, and then enter the required Wi-Fi information in the camera interface. Some cameras also support Wi-Fi setup via a temporary access point (AP Mode) created by the camera itself.
What should I do if after a reset the camera asks for an activation code that I don’t have?
This means the device was previously activated and linked to a cloud account. You'll need to either remember the account details or contact the previous owner to unlink the device. For professional equipment (Hikvision, Dahua), you'll need to recover the password via an export file and contact technical support.
Is it safe to use cameras with factory passwords?
Absolutely not. Cameras with passwords like "admin/12345" are easy prey for botnets and hackers. Attackers scan the internet for such devices and can use them for spying or attacks on other servers. Immediately after restoring access, be sure to set a strong, unique password.
Will the video recordings on the memory card be erased when the password is reset?
A standard software reset (Reset Settings) doesn't affect files on the SD card or hard drive. However, if you select the "Factory Reset" or "Format Storage" option, all archives will be deleted. Be careful when selecting the reset type in the device menu.
How to log into the camera if it has no IP address (DHCP is disabled)?
If DHCP is disabled on the camera and a static IP address is assigned that doesn't suit your network, use the manufacturer's search tools (SADP, SearchTool). These tools operate at the MAC address level and can find the device regardless of its IP settings, allowing you to change them to the correct ones.
