Appendix A: Troubleshooting

Refer to the following for solutions to some error situations.

I.Error occurs while installing or when starting up the Mobile View Software

a.Please make sure that the old version of the Mobile View Software on the mobile device is uninstalled. Then reinstall the Mobile View Software again.

b.If the software’s version number ends in an odd number, please try to install new software with version number ends in even number.

II.Error occurs while connecting to a DVR or a Video Server

a.Basically, most errors occurred due to incorrect network settings.

1.Please check if the network function works properly on the mobile device.

2.If the network function works fine on the mobile device, please make sure that the mobile device allows the Mobile View Software to access network. (Check the network privilege settings of Java programs.)

3.Please disable proxy or select correct port for the target device.

b.For causes other than incorrect network settings, error messages will be displayed. The most frequent situations are listed as below.

1.Errors regarding failure of HTTP/ Socket connection or malformed address/ port:

i.The address of the target device may be null or inaccessible (only the device types on the supported list are accessible, such as a DVR). Please check the address and port number of the device.

ii.For some mobile devices, the DDNS may not function properly due to the DDNS is not supported by Java platform on the mobile devices. In such cases, users can only use DNS or IP address of the target device.

2.Errors regarding HTTP/ Socket Authentication:

i.Double check the username and password, then try to connect again.

ii.If the username and password are correct, please change port setting of the target device and then try to connect again.

iii.Certain mobile devices may not correctly support HTTP authentication. For these mobile devices, please do not using port 80, 8080 or 443. Currently tested mobile devices that cannot correctly support HTTP authentication are Nokia 6233, Sony Ericsson K600i, and Toshiba 810T/908A.

iv.If the mobile devices do not support authentication, the mobile surveillance is not available due to almost all network access to DVR must be authenticated. The tested case is Sharp WX-T81.
