After internet researching to find out how to connect 2 or more IP cameras or other devices to a single PC, I bought a network switch. A switch is sort of opposite to a router. This would hopefully achieve connection to the IP camera and an Ethernet-equipped Arduino (EtherTen) in the ROV. It would also mean that a microcontroller connected directly to the IP camera serial out would not be required, as all control would be done by the Ethernet-equipped Arduino. Maybe time for a new thread called IP camera for video only....
Recently I have be learning about Arduino programming. The EtherTen has an SD card in it containing a simple webpage I created for a SONAR project. Anyway, I plugged the EtherTen and the ROV with camera inside and the PC into the switch and it all worked straight away with no changes to anything
