PoE Switches for IP Security Cameras

Q: What's the difference between IEEE 802.3af, at, and bt standards?

These are PoE power standards: 802.3af (PoE) — 15.4W, 802.3at (PoE+) — 30W, 802.3bt (PoE++) — 60-90W.

PoE Switches — For IP Cameras in Tbilisi

PoE switches (Power over Ethernet) are network switches in Georgia that supply power and data to IP cameras over a single Ethernet cable. This simplifies installation (no separate power supplies needed for each camera), reduces costs, and allows camera placement anywhere without access to electrical outlets. LAGI offers PoE switches in various configurations: 4-port PoE switches for small systems (2-4 cameras), 8-port PoE switches for medium systems (4-8 cameras), 16-24 port PoE switches for large systems (12-24 cameras). All models support IEEE 802.3af/at/bt standards, Gigabit speed, VLAN configuration, and PoE budget 120W-370W.

Key Advantages of PoE Switches

Single cable — power and data over one Ethernet cable, simplified installation.
Cost savings — no separate power supplies needed, reduces costs by 40-50%.
Flexibility — place cameras anywhere without electrical outlet access (ceiling, facade, pole).
Centralized power — all cameras powered from one PoE switch, UPS protection for entire system.
Gigabit speed — 1000Mbps ports for 4K cameras, no bottlenecks.
IEEE 802.3 standards — support for af (15.4W), at (30W), bt (60-90W) for all camera types.

FAQ — Frequently Asked Questions

What is PoE and how does it work?

PoE (Power over Ethernet) is technology that allows transmitting power and data over one Ethernet cable. PoE switch supplies DC power (48V) over unused pairs of Ethernet cable, and IP camera receives this power and converts to required voltage. Maximum distance — 100m.

What's the difference between IEEE 802.3af, at, and bt standards?

These are PoE power standards: 802.3af (PoE) — 15.4W per port, sufficient for standard IP cameras. 802.3at (PoE+) — 30W per port, required for PTZ cameras with IR illumination. 802.3bt (PoE++) — 60-90W per port, required for powerful PTZ cameras, multisensor cameras.

What is PoE Budget and how to calculate it?

PoE Budget is the total switch power for all ports. Example: 8-port PoE switch with 120W budget — if each camera consumes 15W, you can connect 8 cameras (8×15W=120W). If cameras consume 30W (PTZ), you can connect only 4 cameras (4×30W=120W). Always leave 20% reserve.
