3G Routers Providing Remote Access for CCTV
A 3G Router combined with a fixed IP SIM card provide an easy, low cost and reliable way to remotely connect to your CCTV equipment using the 3G wireless broadband services in the UK.
Once a Fixed IP SIM card has been inserted into the SIM slot of a 3G router, lets take the proroute H820 as an example, and the antennas connected and power supplied, the router will connect to the 3G network and provide a high speed (up to 21Mbps) 3G connection.
To connect to the router remotely, simply open a web browser and type in the IP address and you can manage the router settings remotely.
Using Port forwarding settings within the router you are also able to connect to your devices on the LAN side of the router, for example if you have a DVR connected and the LAN IP address of the DVR is 192.168.8.100 and the DVR uses port 80 then you would set the port forwarding up to maybe use an external port of 5555 (becuase the router uses Port 80 also so you do not want to use extenral port 80) so when remotely connecting you would enter the IP address followed by colon folowed by the port eg 18.104.22.168:5555, whgen this gets to the router, the port forwarding settings will route this inbound traffic to LAN IP address 192.168.8.100 port 80 so you can connect to your DVR.
You can see an example below of using the Teltonika RUT500 with Port Forwarding using a standard 3mobile SIM ie. not using a Fixed IP SIM card.
