Why It Works Well for AV-over-IP
- Supports multicast traffic.
- VLAN segmentation for AV and corporate networks.
- QoS prioritization for video streams.
- High backplane bandwidth minimizes congestion.
- 10G uplinks support large video distribution systems.
PoE Capabilities
The switch provides:
- Total power budget: 300W
- Maximum output per port: 30W
Typical devices powered directly include:
- AV-over-IP encoders/decoders
- Wireless access points
- IP surveillance cameras
- Touch panels
- VoIP phones
- Control processors
Example Power Allocation
| Device | Qty | Power |
|---|---|---|
| AV Encoders | 8 | 8 × 15W = 120W |
| AV Decoders | 8 | 8 × 15W = 120W |
| Wireless APs | 2 | 2 × 20W = 40W |
| Total | 18 Devices | 280W |
Within the switch’s 300W PoE budget.
Advanced Network Features
VLAN
Separates AV traffic from:
- Corporate LAN
- Security systems
- Guest networks
QoS (Quality of Service)
Prioritizes:
- Video streams
- Audio streams
- Control signals
ACL (Access Control Lists)
Provides:
- Traffic filtering
- Security policies
- Device access restrictions
IGMP Support
Important for:
- Multicast video distribution
- Efficient bandwidth utilization
- Large AV-over-IP deployments
Advantages
✅ 24 PoE-enabled Gigabit ports
✅ 4 high-speed 10G SFP+ uplinks
✅ 300W PoE budget
✅ Managed Layer 2/3 functionality
✅ Ideal for AV-over-IP systems
✅ Rackmount-ready design
✅ Supports VLAN, QoS, ACL, and multicast traffic
Considerations
❌ 300W PoE budget may be limiting for very large deployments with high-power devices.
❌ Gigabit edge ports are sufficient for H.264 AV-over-IP but may be restrictive for uncompressed 4K AV-over-IP solutions.
❌ Requires network configuration knowledge to fully utilize VLAN and multicast features.
Best Use Cases
- Corporate boardrooms
- Digital signage networks
- Universities and campuses
- Houses of worship
- Hospitality venues
- Security monitoring centers
- AV-over-IP distribution systems using H.264 encoders/decoders
When paired with the ZT-IP210E/210D platform, the ZT-IPSW24P serves as the central switching infrastructure, delivering both network connectivity and PoE power for a scalable video distribution system.
