Chapter 9: Remote Access
The CamSS system provides the remote access functions to users. The system transmits the video images
through the following three media to achieve the purpose of remote monitoring.
1. PSTN (Public Switched Telephone Network), i.e. modems plus common telephone lines.
2. LAN (Local Area Network supporting TCP/IP protocols).
3. Internet (supporting TCP/IP protocol), and Intranet (supporting TCP/IP protocol)
Transmission speed varies depending on the transmission/receiving quality of telephone lines and modems.
Comparatively, LAN provides relatively broader bandwidth, which is good for video transmission. When
LAN is used as a transmission medium, the receiving speed at the remote site is almost the same as the local
site.
Click the button. The Remote access selection window will appear. If the Address Book has
already been set up as instructed in Section 3.5, the CamSS system can connect to the available CamSS
Server or modem.
9.1 Remote Access Via TCP/IP
The names and passwords must first be defined. Log in the name and password to the local CamSS system
then connect to the CamSS Server Program. Finally, connect to the remote CamSS system. Those three
groups of user names and passwords must be completely identical for the program to automatically complete
the user auto-login. For defining user access auditing, please refer to Section 3.3.1.
