The Internet is an amazing thing.īut you didn’t come here to talk about networked computers. When you clicked on the link to open this article, you used your Internet connection to read the files that I saved on that server in Washington, and you’re now able to read these words wherever you are in the world. As soon as I’m done, I’m going to hop onto the Internet so I can save these words on a server located in Seattle, Washington. I’m sitting here typing these words at my personal computer in Broken Arrow, Oklahoma. When we apply this back to the computers in our office from above, we’re talking about a giant network of interconnected networks. A grand highway which will give each neighborhood and each individual within the neighborhood access to every other neighborhood in the world. And not just any highway, but the highway. But this time instead of building a network of roads to connect these nine neighborhoods only to each other, we’re going to give each individual neighborhood access to a highway. Just like before, the answer here is going to be to build more roads. No one can go to work, no one can visit their families. There is no connection to the outside world. No one in these isolated neighborhoods has access to anyone outside of their own neighborhood. But let’s say we have six of these neighborhoods in a town. The Internet: Bridging Multiple Networks TogetherĪlright, we have our neighborhood all connected, giving our residents the ability to communicate with their neighbors. Now let’s take this idea and imagine it on a grander scale. The computers are no longer isolated entities, but can now work together in productive ways. They can also access other devices on the LAN, such as a network-attached storage unit (NAS) or an IP camera (see where we’re going with this?). They can export files, send information, and share data. When connected to one another in a local area network, these computers can now communicate in simple and convenient ways. This is called a local area network, or LAN. Like the roads connecting each house to the other, Ethernet cables can connect all nine computers together in a local area to create a network of devices. On their own, these computers are incapable of any external communication, just like the houses with no roads.īut that’s where the almighty Ethernet cable comes into play. In an office, for instance, you might have nine individual computers. You’ve probably guessed by now that the houses in this illustration represent some kind of electronic device, like a computer. Any resident could visit any of their neighbors and have a chat, borrow or lend sugar, collect information, et cetera. Once each house is connected to every other house, proper communication can take place within the neighborhood and only within the neighborhood. ![]() In order to build an effective network of communication in this neighborhood, we would need to lay some roads. (You’re right, they would probably just walk anyway since they’re neighbors, but let’s imagine for the sake of this illustration that they can’t.) If one of these residents wanted to, say, borrow a cup of sugar from their neighbor, there would be no path for them to get from point A to point B. ![]() The houses aren’t connected to any other house. Do you notice anything missing? There are no roads. Here are nine houses in the same neighborhood. A Local Area Network: Bridging Multiple Devices Together That’s where we’re headed throughout the reset of this blog post. To unpack this definition, we have to understand what a “network” is, what the “Internet” is, and how Internet Protocol (IP) cameras work. But without this Internet connection, you can only access your cameras from devices located on the same network as the cameras themselves Yes, it is possible to install your IP security camera without connecting it to the Internet. ![]() Which raises the question: is it even possible to install an IP camera without an Internet connection? That said, if you install IP security cameras on a regular basis, you’re bound to come across a situation where you need to install a camera in a place where there is no Internet access. The Internet is everywhere, and these days it’s hard to imagine a life without it.
