22 Troubleshooting
Symptom
Cannot access the camera via the URL of the “Viewnetcam.com” service.
Authentication window is displayed repeatedly.
It takes time to display the screen.
Cannot access the camera from a cellular phone.
Cause/solution
•Are you accessing the camera using the local address (the IP address used in a local network)? When accessing the camera, use the global address (or the URL registered in the DDNS service) and the port number of the camera as the IP address to be used in the Internet.
•Is the global address of camera (or router) notified to the “Viewnetcam.com” service server?
Log into the “My Account” page of “Viewnetcam.com” website (http://www.viewnetcam.com/) to check the information of the registered camera. If the global address is not displayed for the IP address field, access the camera, and register the user information for the “Viewnetcam.com” service on the [DDNS] tab on the “Network” page of the setup menu. In addition, check the “Status” of “Viewnetcam.com” (on the [Status] tab) and the system log (on the [System log] tab) of the “Maintenance” page of the setup menu.
•Is the user name and password changed? While accessing the camera, when changing the user name and password of another user logging into the camera on another web browser, the authentication window will be displayed each time the screen is changed or refreshed.
•Have you changed the [Authentication] setting? When the [Authentication] setting has been changed, close the web browser, and then access the camera again.
•Are you accessing the camera in the HTTPS mode? In this mode, the refresh interval becomes slower due to decode procession.
•Are you accessing another camera in the same local network via a proxy server?
Configure the web browser to not use the proxy server.
•Are two or more users browsing the camera images simultaneously?
It may take time to display the screen or refresh interval may become slower when two or more users browse the camera images simultaneously.
•Is the URL correct? Or is “/mobile” missing at the end of the URL?
Check if the URL is entered correctly. When accessing the camera from a cellular phone, it is necessary to enter “/mobile” at the end of the URL that is used for the camera access from a PC.
