How do the latest network-attached IP audio systems work? The latest digital IP systems use protocols that are similar to Voice over IP (VoIP) protocols. This communication method also uses Power over Ethernet (PoE) to power the telephones, IP paging systems, and IP intercoms.
These IP audio systems use the network cable rather than using individual wires that go from an amplifier to a speaker. What is the magic behind sending multiple paging announcements on the same wire at virtually the same time?
Arthur C. Clark said, “Any sufficiently advanced technology is indistinguishable from magic.”
Computers are all around us. These sneaky little critters are not only on our desks, they are in our phones, cash registers, refrigerators, stoves. They are also in IP cameras, door access control readers, and network attached paging amplifiers. The world is certainly getting smarter, but have you ever thought about how these computers actually work? Probably not. And, you’re probably saying, ‘Why do I need to know any of this?
Bloomberg Business Week recently published a complete issue dedicated to “Coding”. Why go to the bother? Well the Business Week article says that learning about technology, is good, it’s important, and sometimes essential for helping you keep your job.
Here’s some basic information that could help you stay current. It will help take the magic out of the computer technology we use every day.
Bug, now that’s a word that covers a lot of ground.
Eeck, there’s a bug on the table.
I’m sick. I have some kind of bug.
Don’t bug me!
I love my Volkswagen bug.
And then there’s dreaded. There’s a bug in the system. Our customers rarely find a bug in the IP cameras Kintronics sells, but in the rare instances one finds its way in, they can rest assure we won’t rest until we’ve debugged the system.
