If you have cameras that say invalid username or password or account locked there are a couple of ways to fix this.

This error can happen for a few different reasons explained here.
This usually occurs for a few different reasons. When you set up your NVR and cameras the NVR will share its password with all of the cameras that are connected to it. This means that the cameras will have the same password as the NVR. If you forget the password to the NVR and log in using a unlock pattern then perform a factory reset of the NVR this will not change the camera passwords. So when the NVR reboots and you enter a new password the NVR will then attempt to log into the cameras that are connected to it using this new password which will be incorrect for the cameras. This is one way that you can get this error. The next way this can happen is if you have multiple NVR’s and attempt to move a camera from one NVR to another NVR. Another way this may happen is if you forgot your password and performed the forgot password function. Generally, when you do this the NVR should change the camera passwords as well. However, in rare occasions, some or all of the cameras may not receive the new password information and will still have the old password.

To fix this issue your options are limited.
If you know what the old password is then the fix is fairly simple. You will go to the main menu on the NVR and select Camera in the lower left. Then click on registration from the menu on the left. You will see a list of the cameras that are on your NVR toward the bottom of the screen. Any cameras with errors will have a red dot under status. You will also see a pencil icon next to them. Click on this pencil icon. You will then get a pop up that will allow you to modify the password that the NVR is using to attempt to log in to the camera. Change this password to the previous password or the password that you believe that camera is using. Click connect, apply and ok. If this is the correct password then you should see the camera image appear in a minute. Note that once there has been 3 failed login attempts the camera will lock the account and you will get a message that says account locked. To continue attempting to log in to the camera you will need to unplug the camera or remove the power source from the camera and plug it back in. This will reset the account so you can continue to attempt to log into it.

IF you do not know the old password and you have a PoE switch or a way to power the camera separately from the NVR then you can connect the camera or switch to your router. Then connect a desktop or laptop to that same router. Find the IP address of the camera by using the IP config tool. Then enter the IP address of the camera into your web browser. You will then be presented with the login screen. Click on Forgot password and follow the instructions to reset the password. Note that if an email address was not entered during setup then this function may not work on the camera.

If you do not know the old password and do not have a PoE switch then the only way to reset the password is to manually reset the camera. This is done by disassembling the camera and pressing the small reset button on the motherboard of the camera and holding it for 30 seconds. The camera will need to remain powered when performing the reset. listed below or the locations of the reset button inside various camera models

unscrew the lens portion of the bullet. Then carefully pull out the internals of the camera. The reset button will be located on the side of the motherboard underneath the camera lens as illustrated below. while the camera is still plugged in, press and hold this button for 30 seconds. The camera will reset to the factory defaults and should automatically be recognized by your NVR if it is plugged directly into the NVR. If the camera is plugged into a switch then you will need to perform a device search to add it and possibly modify the cameras IP address to match your default gateway.

unscrew the mounting bracket and remove the eyeball from the mount. Use the provided hex wrench to remove the screws from the back of the camera. Carefully separate the two halves of the camera taking care not to damage the gasket. The reset button will be located on the camera’s motherboard underneath the lens as illustrated below. While the camera is still plugged in, press and hold the reset button for 30 seconds. The camera will reset to the factory defaults and should automatically be recognized by your NVR if it is plugged directly into the NVR. If the camera is plugged into a switch then you will need to perform a device search to add it and possibly modify the cameras IP address to match your default gateway.

Remove these two screws and lift the board out of the mount being careful not to pull on the wires. The reset button is located on the underside of the board as illustrated in the second image below. While the camera is still plugged in, press and hold the reset button for 30 seconds. The camera will reset to the factory defaults and should automatically be recognized by your NVR if it is plugged directly into the NVR. If the camera is plugged into a switch then you will need to perform a device search to add it and possibly modify the cameras IP address to match your default gateway.

There is a small notch at the bottom of the camera’s faceplate as illustrated in the image below. Use a small flat head screwdriver to carefully pry the faceplate off. The faceplate is lightly glued on so you will need to slowly work the plate off. Once you have removed the faceplate there are 4 screws that hold the lens on. Remove these four screws and carefully remove the front lens being careful not to damage the gasket. The reset button is located in the lower left underneath the motherboard as illustrated in the second image below. While the camera is still plugged in, press and hold the reset button for 30 seconds. The camera will reset to the factory defaults and should automatically be recognized by your NVR if it is plugged directly into the NVR. If the camera is plugged into a switch then you will need to perform a device search to add it and possibly modify the cameras IP address to match your default gateway.

Remove the four screws on the back of the PTZ’s dome as illustrated in the image below. The reset button is located in the middle of the motherboard as illustrated in the second image below.
While the camera is still plugged in, press and hold the reset button for 30 seconds. The camera will reset to the factory defaults and should automatically be recognized by your NVR if it is plugged directly into the NVR. If the camera is plugged into a switch then you will need to perform a device search to add it and possibly modify the cameras IP address to match your default gateway.
