Just as with network switches, there are no real standards for midspans In general terms, a midspan is a power over Ethernet (PoE) power source that is placed between a network switch and the device being powered, hence the term midspan. The real question is, with almost all network switches providing PoE power, why do we need a midspan? The answer is, in some cases we don’t, but in others we do. As with any other product we have discussed, we need to first consider that...

Layering as applied to computers is a made up term having no relationship to any particular standards When it comes to setting the criteria for network switching, we often hear “I only want a layer 3 switch.” We naturally assume that since the number 3 is bigger than the number 2, a layer 3 switch must be better than a layer 2 switch. It may surprise you, but when it comes to video security applications, this may not be the case. In fact, just the opposite may...
