Hi Carlfike
The cam I have is a foscam fi8918w and that camera works connected or wireless with your internet router.. The first time you have to connect it and see on your computer the ip that it is using.. that ip is the internal IP that the cam will use on your network, now you need to go to your router settings in my case it is an airport extreme and set a port for the camera... you will add here the IP the cam is using on your network plus the port you want it to work with... example... lets say your camera connected to the IP 10.0.40 .. that port will be the one you add to your port mapping and the port you will use is 5500... this is good as no other stuff use that port..., after that you need to see the IP yout internet connmection is using, generally the ip of the ISP .. you can see it on your newtork settings
That ip plus the port will be your web address to your cam.. example
The IP of your internet connection 123.456.789
Port: 5500
Address: http:// 123.456.789:5500
You will be able to edit your settings online on your browser
It can be motion activated.. I cached a big bristleworm on my tank that way
You do not need a webhosting or a domain name, in y case that is just extra as I have plans to do some blog later..
Hope this information is of help... It as a little complicated first but once you get it is great for you to check you tank
Have a good day
Ernesto
