PoE vs Non-PoE Switches — Which Network Switch Is Best for IP Cameras?

Introduction

Setting up IP cameras, connecting computers or expanding your office network? Choosing the right Ethernet switch can make your installation simpler and more practical.

One common question is: Should you buy a PoE switch or a Non-PoE switch?

The main difference is power delivery. A standard Non-PoE switch connects devices to a network but does not supply power through its Ethernet ports. A PoE switch can deliver both network data and electrical power over a compatible Ethernet cable, making it especially useful for IP cameras and other supported devices.

Let's compare both options, their benefits, use cases and suitability for CCTV installations.

What Is a PoE Switch?

PoE stands for Power over Ethernet. A PoE switch allows compatible devices to receive network connectivity and electrical power through a single Ethernet cable.

For example, a compatible PoE IP camera can connect to a PoE switch using one Ethernet cable for both data and power. This can reduce cabling complexity and the need for a separate power adapter near each camera.

Main benefits of a PoE switch:

One Ethernet cable can carry power and data to a compatible device.
Fewer separate power adapters and nearby power outlets may be needed.
Flexible installation for ceiling-mounted or outdoor cameras.
Centralised power management for supported devices.
A compatible UPS can provide backup power to the switch and connected devices during a power interruption, within the available power budget.

PoE switches can also power compatible wireless access points, VoIP phones and other network device

What Is a Non-PoE Switch?

A Non-PoE switch is a network switch that connects devices through Ethernet but does not provide power through its network ports.

It is suitable for devices that already have their own power source, such as desktop computers, printers, servers and other powered network equipment.

Main benefits of a Non-PoE switch:

Often a cost-effective option for basic network expansion.
Suitable for connecting multiple computers, printers and other wired devices.
Useful when connected equipment already has its own power adapters.
Available in a range of port counts and network speeds for home and business use.

If you want to connect an IP camera to a Non-PoE switch, the camera will still need a separate compatible power source. Another option is a suitable PoE injector, provided it matches the camera's power requirements.

PoE vs Non-PoE Switch: Key Differences

1. Which Switch Is Best for IP Cameras?

For an IP camera installation, a PoE switch is often the more convenient option if your cameras support PoE.

It can carry power and video data over one Ethernet cable, simplifying the connection between the camera and the network. This is particularly useful when cameras are installed on ceilings, exterior walls, shop entrances or other locations where a nearby power outlet may be inconvenient.

However, check these details before buying:

PoE compatibility: Confirm that the camera supports the same PoE standard as the switch.
Power budget: Add up the power requirements of all connected cameras and ensure the switch can supply enough power across its PoE ports.
Number of ports: Choose enough ports for the cameras you plan to connect, with room for reasonable expansion.
Network speed: Check whether 10/100 Mbps or Gigabit Ethernet meets the requirements of your cameras and wider network.
Recording setup: Confirm compatibility with your NVR, router and overall network design.

PoE standards offer different power levels. For example, IEEE 802.3af standard PoE supports up to 15.4W supplied by the power source per port, while IEEE 802.3at PoE+ supports up to 30W per port. The usable power at the connected device is lower due to cable losses. Higher-power devices may require IEEE 802.3bt support.

2. When Should You Choose a Non-PoE Switch?

A Non-PoE switch is a sensible choice when your main requirement is to connect wired devices that already have their own power supplies.

Consider a Non-PoE switch for:

Home networks: Connecting desktop computers, printers, TVs and other wired devices.
Office networks: Expanding Ethernet connections for workstations and independently powered equipment.
Small shops: Connecting computers, billing systems and other networked devices.
Existing installations: Adding network ports where camera or device power is already provided separately.

If you plan to install PoE IP cameras in the future, factor that into your decision. A Non-PoE switch can still be part of the setup, but you may need additional power equipment.

3. Can You Use a Non-PoE Switch with an IP Camera?

Yes, provided the camera receives power separately and the rest of the connection is compatible.

There are two common approaches:

Option A: Separate power adapter

Connect the IP camera to the Non-PoE switch using Ethernet, then power the camera using its supported power adapter.

Option B: PoE injector

Use a compatible PoE injector between the switch and camera. The injector supplies power over the Ethernet cable while the Non-PoE switch handles network connectivity.

Always check the camera's supported power input, injector specifications and cabling before connecting equipment. A standard Non-PoE switch alone will not power a PoE camera.

4. Where Should You Use Each Switch?

PoE switch : CCTV and connected devices

Best suited to compatible IP cameras, wireless access points and VoIP phones. It is especially helpful when devices are mounted far from convenient power outlets.

Non-PoE switch: Everyday wired networking

Ideal for connecting computers, printers and other independently powered equipment at home, in offices, shops and classrooms.

5. What About Managed and Unmanaged Switches?

PoE and Non-PoE describe power delivery, while managed and unmanaged describe network control. These are separate features.

Unmanaged switch: Usually the simpler option for basic plug-and-play connectivity.
Managed switch: Offers more control over network settings and may support VLANs, traffic prioritisation, monitoring and other advanced functions.
Managed PoE switch: Can be useful for larger camera networks that need more visibility and control over connected devices.

Choose the combination that fits your network requirements rather than assuming every PoE switch has advanced management features.

Final Verdict: PoE or Non-PoE?

Choose a PoE switch when you want a simpler installation for compatible IP cameras or other PoE-powered devices. Choose a Non-PoE switch when you primarily need network connections for equipment that already has its own power supply.

For CCTV installations, a PoE switch is often the more convenient choice—but only when its PoE standard, power budget, port count and network specifications match your cameras.
