In a home, there are 5 users, of which 2 are desktop users and remaining wireless. All users should have access to the internet. An IP camera is to be integrated in the home network which should be accessible from the internet.
There are 5 users on the network, of which 2 are desktop users for which 2 physical ports would be required. The IP camera would require 1 physical port. A switch with minimum number of 3 ports would be required. A wireless access point is also required for accommodating the wireless users. An ADSL wireless router with inbuilt modem, 4 port switch and wireless access point can be used for the purpose. The LAN interface of the router is configured with the IP address 192.168.1.1.The WAN interface of the router either receives a public IP address or is configured with a static IP address based on the settings provided by the ISP. The IP camera is configured statically with the IP address 192.168.1.2. The IP addresses for the PCs and laptops along with the gateway addresses are assigned by the DHCP server on the wireless router. Port forwarding is configured on the wireless router to the IP address, 192.168.1.2 of the camera.
The port 80 is forwarded for the IP address, as the web interface of the camera is used for viewing activities. The port number may vary based on the camera make and model. Users from the internet open the browser and connect to the public IP address of the router, which would then be forwarded internally to the camera on the inside
