If you cannot login to your camera because you have forgotten the root username password, you will need to manually restore the camera to its factory default settings. To do this, get a paperclip and insert it into the pin sized hole on the back of your camera and hold for 20 seconds. After the initial 20 seconds, remove the power, while still holding the paperclip in the back of the camera. After 10 seconds, plug the power back into the camera and wait for another 30 seconds. After the 30 seconds remove the paperclip and your camera will reset to its factory settings. From here you will need to run the IP Installer to reconfigure your camera.
