The problem with your Hikvision DVR camera is that it is connected to the internet but shows a disconnected status on your mobile phone.

Here are some steps you can try to resolve the issue:

1. Make sure that the DVR device is properly connected to the internet. Check the cables and ports to ensure they are properly connected.

2. Check the network settings on the DVR device. Make sure that the IP address of the device is correctly configured and compatible with your local network.

3. Restart both the DVR device and your router. Sometimes a simple connection conflict can be resolved by restarting the devices.

4. Check the firewall settings on your router. There may be security rules that prevent the DVR device from connecting to the internet. Check the firewall settings and ensure that they allow the device's connection.

5. Check the surveillance application on your mobile phone. Make sure you are using the correct application and that the connection settings are correct.

6. It may be necessary to update the drivers or software on the DVR device. Check the manufacturer's website for the latest software versions and updates.

If these steps do not solve the problem, it is recommended to contact the technical support of the manufacturer for further assistance and more detailed instructions based on the specific DVR device you are using.

To check the firewall settings:

To check the firewall settings on your router, you can follow these steps:

1. Open a web browser on a computer connected to the local network.

2. Type the default IP address of the router into the browser's address bar. The address is typically "192.168.1.1" or "192.168.0.1," but you may have a different address. If you are unsure of the address, you can refer to the router's user manual or search online using the model name to find the correct address.

3. You will be directed to the login page of the router device. Enter the correct username and password. If you don't know the login information, you can check the user manual for the default credentials or contact the manufacturer's technical support.

4. After successful login, you will see the router's settings interface. Look for the Security, Protection, or Firewall section. The section names and options may vary depending on the router device you are using.

5. Check the firewall settings. You may have options to allow connections from the DVR device through the network. Make sure the firewall is not blocking or hindering the connection between the DVR device and the internet.

6. If you cannot find the firewall settings in the router interface, you may need to consult the user manual or contact the manufacturer's support.

How to check network settings on the device?

To check the network settings on a DVR device, you can follow these steps:

1. Power on the DVR device and make sure it is connected to a display monitor or TV.

2. Look for the Menu or Settings button on the DVR device. There may be a dedicated button to access the main menu.

3. Use the navigation buttons (Up, Down, Right, Left) to navigate the menu and look for the Network section or Network Settings. You may have a dedicated network section or a general section that includes network settings.

4. Inside the Network section, you may find options such as IP settings, Connection settings, or DHCP. Make sure the current settings are compatible with your local network and internet service provider.

5. If you have a static IP address for the DVR device, ensure that the entered address is correct and does not conflict with any other IP addresses on the network.

6. If you are using DHCP to obtain an IP address automatically, make sure it is enabled and functioning correctly.

7. You may also need to input the default gateway and DNS server settings of your internet service provider.

8. Once you have verified and properly configured the network settings, save the changes and restart the DVR device.

Please note that the interface and network settings may vary depending on the DVR device you are using.

After performing a factory reset, it is easy for an average user to log in and establish an internet connection again. The factory reset process restores the default settings of the device, including the default username and password to access the control interface.

After the reset, you should use the default username and password to log in to the camera's control interface. Refer to the manual or documentation that came with the camera to obtain the default username and password. Once logged in, you can reconfigure the internet connection through the network settings in the control interface, such as setting a static IP address or using DHCP to obtain an IP address automatically.

It is important to change the default password to a strong and complex password after logging in to ensure the security of the camera and protect access to it.
