How to resolve the conf.loginerrorNo-20 in Dahua (error code 20)

conf.loginerrorNo-20

Compatibility concerns are the root cause of the Dahua conf.loginerrorNo-20, and it manifests itself most often when more recent Dahua IP cameras are linked to more established (PoE or conventional) NVRs.

Error 20 may be shown on the NVR itself (on the monitor that is linked to the recorder) under some circumstances. However, the cameras may function normally when viewed via the web interface (Internet Explorer or Mozilla) or using the Smart PSS tracking software.

This issue may be remedied in a few different ways: the firmware of the NVR can be updated to the most recent version (if there is one), or the camera can have its settings restored to their factory defaults, after which it can be activated via the menu on the NVR (this method works on certain models only).

Fix Dahua conf.loginerrorNo-20 problem

Improve the NVR system.

According to what we’ve established so far, the majority of the time the problem is due to compatibility concerns, which arise when the camera is more recent and the NVR is older. To put it another way, there is a compatibility issue with the software, and as a result, the cameras are unable to interact effectively with the NVR.

In the event that you receive error code 20, the very first thing you need to do is locate the most recent version of the NVR’s firmware and then upgrade it. You may get the firmware by visiting the official website of Dahua or by contacting your vendor or reseller.

Give them the model number of the NVR, put the firmware on a USB stick, and then insert the disc into the NVR. After that, follow the on-screen steps (or, you can update via the website).

After the update is complete, the NVR will restart, and once it is back online, you should find that the cameras are functioning normally.

In the event that there is not a new firmware update, you will need to either upgrade the NVR to a more recent model or degrade the cameras (older cameras, lower the resolution).

Perform a factory reset on the camera, then activate it using the NVR.

Occasionally, the Dahua error 20 is brought on by problems with the camera’s password; specifically, the NVR is unable to activate the camera using the password. The problem may be fixed by resetting the camera to its factory settings and activating it through the NVR (the camera and the NVR will have the same password).

You are able to reset the camera in one of two ways: either by using the reset button, as described in this article, or by visiting the camera directly using a web browser (using its IP address) and selecting the Default Factory option, which is located inside the camera’s settings.

When you are through with the reset, you will need to enable the camera using the NVR. Assuming you have a PoE NVR, you would first connect the camera to the rear of the recorder. Next, you would go to the Gadget Search part of the interface and search up the cameras that were detected by the recorder. Mark the camera that has the white logo on it, and then choose to Initialize from the menu.

You will be prompted to confirm that you would want to use the NVR’s email address and password. If you choose this option, the NVR’s password will be used for the camera, and the camera’s recovery email will be the same as the one used for the NVR.

To put it another way, the password and email address for the camera as well as the NVR will be the same. After you have done so, restart the NVR, and after it has come back up, you should be able to see the picture from the camera displayed correctly on the screen.

Note: In addition, you may activate or initialize the camera by using the Config Tools, which also allows you to create a password for the camera.

You need to manually add the camera.

Another option is to add the camera to the NVR using the manual interface. Sometimes the NVR is unable to automatically add the camera to the recording (or adds it with errors). Simply go to the Device/Remote area, and then pick Manual Add from the drop-down menu.

Please provide the requested information, including the IP address of the camera, the access, and the password. Leave the rest of the settings as they are. After clicking the Add button, you will need to wait to check whether the camera becomes online.

You may add the camera by using ONVIF.

The camera is just added as an ONVIF gadget for this approach to function properly. If both the NVR and the camera are manufactured by Dahua, then they should be able to communicate with one another through the “private” protocol.

If, on the other hand, the cameras are more recent and the NVR is older, we may sidestep the compatibility problems by installing the gadgets as ONVIF.

To do this, go to Device/Remote and then select the Add Manually button. Complete the required fields, which may include “ONVIF” as the manufacturer, “554” as the RTSP port, “80” as the HTTP port, your username, and password, and so on (as shown on the screenshot below).

After clicking the OK button, you will need to wait for the camera to switch to live mode. In order for the modifications to take effect, you may sometimes need to restart the NVR.

Put the device into compatibility mode.

You may use your web browser to access the camera. You may get access to the camera in one of two ways: either by connecting it to the local area network or by putting the IP address into your browser.

You also have the option to visit the NVR, go to the Registration menu, and then choose the Internet Explorer icon that is located next to the camera that is giving you trouble.

The web application for the camera will load into a new page that opens up when you click the button. Please enter your login and password to access the camera.

To turn on the Compatibility Mode, go to the Settings menu, then choose System, then select Safety, and finally select System Service. Adjust the Private Protocol Authentication Mode so that it is compatible with the other modes.

Reduce the camera’s resolution to a lower setting.

There are occasions when the NVR is unable to manage the resolution that is being sent from the camera. Let’s assume the resolution of the camera is 4 megapixels, but the NVR only supports 2 megapixels. In this scenario, you will need to reduce the resolution of the camera so that it is compatible with the NVR’s capabilities.

Right-clicking the Live View display will bring up the Quick Menu; from there, choose Main Menu to access the rest of the menus. After clicking the gear icon, choose the Recording section from the menu that appears. To start recording, choose the Recording tab from the top panel.

At this point, you will need to reduce the camera’s resolution until the image appears on the screen. In addition, you may try slowing down the frame rate and experimenting with various compression options until the image appears on the screen. You should, in essence, experiment with the parameters until you find the optimal combination.
