Small businesses, retail stores, offices, clinics, warehouses, and residential properties increasingly rely on IP cameras for security. Unlike traditional analog CCTV systems, IP cameras use network connectivity to transmit video, making the network switch an important part of the surveillance infrastructure.
For smaller installations, an 8 port POE switch can provide an efficient way to connect and power multiple IP cameras using Ethernet cables. PoE, or Power over Ethernet, combines power and data transmission through a single network cable, simplifying installation and reducing the need for separate power adapters.

However, choosing the right switch requires more than simply counting ports. Power budget, Ethernet speed, uplink capacity, camera requirements, cable distance, and future expansion should all be considered.

What Is an 8 Port PoE Switch?

An 8 port POE switch is a network switch designed with eight Ethernet ports that can provide both network connectivity and power to compatible PoE devices.
For CCTV installations, each compatible IP camera can connect directly to a PoE port. The Ethernet cable carries the camera’s network traffic while also supplying power.
This approach can simplify surveillance installation because cameras do not necessarily need separate local power adapters or electrical connections. It can be especially useful when cameras are mounted on ceilings, walls, poles, or other locations where access to power outlets may be inconvenient.
A small PoE switch can also connect other compatible devices, including wireless access points, VoIP phones, and intercom systems, depending on the network requirements and available PoE capacity.

Why Use PoE for CCTV and IP Cameras?

PoE provides a practical advantage for surveillance networks because power and data can travel through the same Ethernet connection.
Consider a small retail store with six IP cameras. A conventional installation may require network connectivity as well as individual power arrangements for each camera. With compatible PoE equipment, the cameras can connect directly to the PoE switch.
This can reduce cabling complexity and make the installation easier to organize. It can also simplify troubleshooting because network connectivity and power delivery are centralized at the switch.
For businesses expanding their security infrastructure, PoE can therefore provide a cleaner and more scalable approach to IP surveillance.

How Many Cameras Can an 8-Port Switch Support?

An 8-port PoE switch can provide connectivity for up to eight directly connected PoE devices, subject to the specific model’s configuration.
However, the practical number of cameras depends on more than port count. You should consider the power requirements and bandwidth generated by each camera.
A basic fixed IP camera may require significantly less power than a camera with additional functions. Similarly, higher-resolution cameras can generate greater network traffic.
Before installation, calculate the total power requirements of the cameras and compare them with the switch’s total PoE power budget. This ensures that the switch can support the planned devices reliably.

Key Features to Check Before Buying

1. PoE Power Budget

The total PoE power budget is one of the most important specifications for CCTV deployments.

A switch may have eight PoE ports but still have a limited total power budget. If multiple cameras require higher power, the total consumption must remain within the switch’s available capacity.
For example, Dasscom’s DES-82MG supports IEEE 802.3af/at, provides up to 30W per PoE port, and has a 120W total PoE budget.

2. Port Speed

Camera video streams continuously use network bandwidth. Resolution, frame rate, compression, and bitrate all influence bandwidth requirements.
When selecting an 8 port POE switch, check the speed of the camera-facing ports as well as the uplink ports.
Dasscom’s DES-P82GS2, for example, provides eight 10/100/1000Base-T PoE ports and two 100/1000Base-X SFP uplink slots, offering Gigabit connectivity on its PoE ports and fiber-capable uplinks.

3. Uplink Capacity

The uplink connects the PoE switch to equipment such as an NVR, router, server, or another network switch.
This becomes important when multiple cameras transmit video simultaneously. A suitable uplink helps move aggregated camera traffic from the access switch toward the NVR or wider network.

4. PoE Standard

Check which PoE standard the switch and cameras support.
Dasscom’s DES-P82M supports IEEE 802.3af/at, with its ports supporting up to 30W per port and a maximum PoE output of 96W. It is designed to support devices such as network surveillance cameras and wireless access points.
Compatibility between the switch and cameras should always be confirmed before deployment.

These options allow businesses to select an 8-port PoE solution based on their required port speed, uplink architecture, power budget, and deployment environment.

8-Port vs. 16-Port PoE Switch

An 16 port POE switch becomes a better option when the CCTV installation has more cameras or requires additional capacity for future expansion.
An 8-port solution is generally appropriate for smaller installations where the number of connected devices is limited. A 16-port switch provides additional ports and can accommodate a larger surveillance deployment without immediately requiring another switch.
For example, a small shop with four to six cameras may not need 16 PoE ports. A larger office with 10–14 cameras may benefit from moving to a 16-port configuration.
The decision should therefore be based on the current camera count, planned expansion, and the other PoE devices that will share the network.

When Do You Need a 24-Port Managed Switch?

A 24 port managed switch is generally more appropriate for larger or more complex networks.
If CCTV is only one part of the infrastructure and the same network also supports computers, IP phones, wireless access points, servers, and other devices, additional ports and management capabilities can become valuable.
A 24 port managed switch can also provide greater control through features such as VLANs, traffic management, monitoring, and network segmentation, depending on the model.
For a small standalone CCTV installation, however, an eight-port PoE switch may be a simpler and more economical solution.

Consider Cable Distance

Camera location should also influence switch selection.
Ethernet networks have distance limitations, so the physical distance between the switch and each IP camera should be considered during network planning.
For a small office, cameras may be located close enough to the network rack for standard Ethernet cabling. Larger facilities such as warehouses, campuses, and factories may require a more carefully planned network architecture.
Some Dasscom PoE models include extended transmission features. For example, the DES-P82M datasheet specifies an extend mode supporting up to 300 metres under its stated operating conditions and limitations.
Always evaluate the actual cable type, distance, bandwidth, and operating conditions before deploying long-distance camera connections.

Managed or Unmanaged PoE Switch?

For a simple CCTV installation, an unmanaged switch can offer plug-and-play deployment with minimal configuration.
Managed switching becomes more valuable when the network requires greater control. Businesses may need to separate surveillance traffic, voice traffic, employee devices, and guest connectivity using VLANs or monitor network performance.
A 24 port managed switch may therefore be appropriate for a larger business infrastructure, while an unmanaged 8-port PoE model can be a practical choice for a compact surveillance system.
The right choice depends on the complexity of the network rather than simply the size of the business.

Common Mistakes to Avoid

The first mistake is selecting a switch based only on the number of ports. PoE power capacity and uplink bandwidth are equally important.
The second is ignoring future expansion. If additional cameras are likely to be installed, leave sufficient port and power capacity.
Another mistake is overlooking camera power requirements. Cameras with additional functions may require more power than basic models.
Finally, do not overlook uplinks. Multiple camera streams need to reach the NVR or network core, so uplink capacity should be considered as part of the overall design.
