The XXCamera application doesn't have its own username and passwordб which means that the username and password used are for the cameras you added to the database through XXCamera. This little program simply allows you to add CCTV or remote cameras to watch the live stream. If you have an issue with the camera, then local maintenance needs to be performed for the camera. Try removing the camera from application, then add it back and retype your credentials. If it still doesn't work, connect a PC to the camera and access the administration menu to change the password.
Additionally, consult the manual of the camera to learn how to reset it.
