CT-5322F/CT-5642F User and Installation Guide62Accessing a Remote Unit over the Webioi Thermal cameras enable IP access to a camera that does not have built-in IP capability. Furthermore, it ispossible to remotely access a unit that is located behind a firewall at a remote site. ioi Thermal does this byusing port forwarding, which enables three functions:1. Transmitting videos over remote networks.2. Remote configuration of the unit over the web. The web setup supports login, all setup functions,and video display configuration.3. Remote configuration of the video analytics module.Port forwarding maps and enables communication between an external IP address (accessible over theInternet) and an internal IP address (assigned to a unit on a private network located behind afirewall/router with or without a firewall), which is not directly accessible over the Internet. ioi Thermalcameras enable IP access to a camera that does not have built-in IP capability.Figure 66: Remote Access SystemThe following port forwarding table displays an example of the mapping between the external IPaddress/port and the internal IP address/port:Camera # External IP Address:Port Number Internal IP Address:Port NumberCamera 1 172.168.123.30:180 10.30.75.10:80Camera 1 172.168.123.30:181 10.30.75.10:8080Camera 1 172.168.123.30:182 10.30.75.10:554Camera 2 172.168.123.30:280 10.30.75.11:80Camera 2 172.168.123.30:281 10.30.75.11:8080Camera 2 172.168.123.30:282 10.30.75.11:554Camera 3 172.168.123.30:380 10.30.75.12:80Camera 3 172.168.123.30:381 10.30.75.12:8080Camera 3 172.168.123.30:382 10.30.75.12:554
