When setting up a network, choosing the right switch is crucial. One of the most common decisions is whether to use a PoE (Power over Ethernet) switch or an ordinary switch hub. While both devices serve as network switches, they have key differences that impact how they function in various applications, especially in CCTV systems, VoIP, and enterprise setups.


What is an Ordinary Switch Hub?

An ordinary switch hub, also known simply as a network switch, is a device that connects multiple devices within a local network. It forwards data between devices, ensuring seamless communication. However, it does not provide power to connected devices—each device must have its own power source.

Key Features of an Ordinary Switch:

✔ Transfers data between connected devices.
✔ Requires separate power adapters for IP cameras, phones, and access points.
✔ Suitable for basic home and office networks.

What is a PoE Switch?

A PoE switch functions like a regular switch but has the added ability to deliver electrical power through Ethernet cables. This means it can power PoE-enabled devices like IP cameras, VoIP phones, and access points without the need for additional power adapters or outlets.

Key Features of a PoE Switch:

✔ Transfers both data and power over a single Ethernet cable.
✔ Eliminates the need for extra power cables or adapters.
✔ Ideal for CCTV security systems, wireless access points, and VoIP phones.
✔ Supports different PoE standards (e.g., PoE, PoE+, PoE++) for various power requirements.

Which One Should You Choose?

  • If you’re setting up a simple home or office network with standard devices like computers and printers, an ordinary switch hub is enough.
  • If you're installing IP cameras, access points, or VoIP phones, a PoE switch is the better choice since it reduces cable clutter and simplifies installation.
