PoE Network Switches — Power Over Ethernet

PoE/PoE+/PoE++ switches for IP cameras, wireless APs, and VoIP phones

About PoE Network Switches

Power over Ethernet (PoE) switches deliver both data and electrical power over standard Ethernet cables, eliminating the need for separate power adapters at each device. This is essential for deploying IP security cameras, wireless access points, VoIP phones, and IoT sensors — devices that are often ceiling-mounted or installed in locations without convenient power outlets.

PoE standards determine how much power each port can deliver: PoE (802.3af) provides 15.4W per port for basic devices like VoIP phones, PoE+ (802.3at) delivers 30W for IP cameras with pan-tilt-zoom and outdoor heaters, and PoE++ (802.3bt) supplies up to 60-90W for high-power devices like digital signage and LED lighting panels.

PoE Switch Options by Use Case

8-Port PoE+ Unmanaged — small office, 4-8 cameras or phones
24-Port PoE+ Managed (370W budget) — branch office, 20+ cameras + APs
48-Port PoE+ Managed (740W budget) — enterprise floor, campus deployment
Cisco Catalyst 9300 PoE+ — enterprise-grade with UPOE and SD-Access
HPE Aruba 6300M PoE — layer 3 PoE switch for Aruba CX ecosystem
Juniper EX3400-48P — 48-port PoE+ with Virtual Chassis support

When sizing a PoE switch, calculate total power budget — not just port count. A 24-port PoE+ switch with a 370W budget can only power 12 devices at full 30W each. Tell us your device list and we will recommend the right switch with adequate PoE budget.

Frequently Asked Questions

What is the difference between PoE, PoE+, and PoE++?

PoE (802.3af) delivers 15.4W per port, suitable for basic IP phones and low-power cameras. PoE+ (802.3at) delivers 30W per port, needed for PTZ cameras, outdoor cameras with heaters, and 802.11ac/ax access points. PoE++ (802.3bt Type 3/4) delivers 60-90W, required for digital signage, LED lighting, and high-power APs. Most modern deployments should use PoE+ switches as the baseline.

How many cameras can a PoE switch power?

Divide the switch's total PoE budget by the power consumption of each camera. A typical fixed IP camera draws 10-15W, PTZ cameras draw 20-30W, and outdoor cameras with IR and heaters draw 25-40W. A 24-port switch with 370W budget can power approximately 24 fixed cameras (15W each) or about 12 PTZ cameras (30W each). Always leave 20% power headroom for peak draws.

Do I need a managed or unmanaged PoE switch?

Unmanaged PoE switches are plug-and-play — ideal for simple camera or phone deployments under 16 ports. Managed switches add VLANs, QoS, IGMP snooping, and port security — essential for enterprise networks with mixed traffic, surveillance video that needs QoS prioritization, or environments requiring 802.1X authentication. For IP camera deployments over 16 cameras, managed switches are strongly recommended.
