Web Interface is available on port 85 as http://camera-ip:85. Default login and password are admin and 12345, respectively.
In some cases, especially if it seems that something is not working, you might need to re-install the web interface update by checking the "Install even if matches the existing version." checkbox.
Double updating of the web interface can be necessary if we've made some changes to the code of updating procedure per se. In such case, the first update routine will install the modified code, and the second round will be performed using that updated code.
