8 Port PoE Switch: Complete Guide for Small Networks & CCTV
Author : Dasscom dasscom | Published On : 19 Oct 2026
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.
