You likely have insight into Power over Ethernet (PoE) if you are reading this. PoE is a technology that transmits data and electric power via twisted-pair Ethernet cables to VoIP phones, IP cameras, and wireless access points. It allows a single RJ45 patch cable to provide both a data connection and electric power to connected edge devices, eliminating the need for a distinct cable for each function.
Conversely, a network switch is a hardware device that establishes connections between devices on a local area computer network. It enables the connection of printers, PCs, wireless access points, and other network-capable devices.
This brings us to the subject of our discussion today: what is a POE switch? This is a standard Fast Ethernet or Gigabit network switch that includes Power over Ethernet functionality. In reality, it facilitates communication among network clients and supplies power to PoE-enabled edge devices via the same RJ4 network cable.
Why do I need a POE switch, you may be wondering. Cost savings associated with installation are among the most noteworthy advantages. It is important to remember that bringing conventional power to locations where it is not available can be very expensive.
This assumes that you wish to install cameras in the warehouse’s section that lacks power outlets. In the absence of a POE switch, it would be necessary to consult a certified electrician, as it is highly probable that a network administrator would be unable to complete the electrical installation.
The low-voltage application of PoE typically results in distinct circumstances, as it is feasible for virtually anyone to connect network cables from the cameras to a PoE switch. You can save even more money by using PoE because you won’t need to install power receptacles, electrical wiring, or breaker boxes.
It does not conclude there, as PoE devices can be effortlessly installed in locations that lack power receptacles. Those previously difficult-to-reach locations can now be accessed with greater simplicity, as they no longer require a standard outlet to function.
Since you only need one network cable to get power and network connections, installing a PoE network camera high up on the wall or roof is no longer a daunting task. You should never overlook the simple fact that you can access them via the internet or a local network. You now have insight into the advantages of POE switches, so why not think about installing one?
