ACTi PPSW-1101 PoE Network Switch

We've deployed the ACTi PPSW-1101 across a range of surveillance projects — from single-building campuses (24–30 cameras) to distributed multi-site operations with cascaded switches. The value proposition is straightforward: it eliminates the complexity and cost of bolting separate PoE injectors onto an unmanaged switch. For integrators accustomed to 4-port or 8-port injectors daisy-chained with consumer-grade Netgear or TP-Link switches, the PPSW-1101 feels like a mature, purpose-built appliance. The 440W budget is generous enough to handle the full ACTi professional camera portfolio — including their PTZ units with integrated heaters — without oversubscription or the need for power negotiation trickery. On the flip side, if you're mixing brands aggressively (high-draw Hikvision turrets at 60W+ each alongside ultra-low-power Axis compacts), you'll want to audit the per-port power draw before commitment. We've also seen sites where the single AC inlet becomes a liability: a loose power cord or tripped breaker takes down the entire 24-camera infrastructure. For mission-critical deployments, UPS pairing is non-negotiable. The managed switching features (VLAN, QoS) are genuinely useful — not afterthoughts. We use them to isolate surveillance traffic during network maintenance, deprioritize bandwidth-hungry camera firmware uploads, and carve out a separate VLAN for forensic recording streams. The ONVIF compatibility is real, and we've integrated it with Milestone, Genetec, and Axis Camera Station without friction. The caveat: firmware updates are ACTi-controlled, not vendor-agnostic, so long-term support depends on ACTi's release cadence.

Technical Highlights:

• 440W PoE+ (802.3at) Budget across 24 Ports: This translates to 18–20W per port on average, sufficient for a 5MP outdoor dome with IR and heater, or a multi-megapixel PTZ unit. We've stress-tested mixed loads (10 domes + 8 PTZ units + 6 compact Axis cameras) and the switch holds power delivery flat across a full 24-hour cycle — no thermal throttling, no port fallback.
• 48 Gbps Non-Blocking Backplane: Actual throughput bottleneck is the gigabit ports themselves (2x1 Gbps per port direction). At 15 cameras averaging 12 Mbps each, you're using ~180 Mbps of aggregate bandwidth — roughly 0.2% of the backplane. The switch will never be your throughput constraint on a single-switch deployment.
• 802.1Q VLAN Support with QoS: In practice, this lets you tag camera streams, management SNMP, and NVR heartbeat traffic with different VLAN IDs, then assign priority queues. We've used this to throttle bandwidth-heavy firmware uploads so they don't starve live recording. Most managed switches at this price tier include VLAN support; the PPSW-1101 implements it cleanly via a web UI or CLI.
• IGMP Snooping: Multicast video (e.g., motion-triggered streams sent to multiple NVRs) doesn't flood every port. In large deployments, this reduces unnecessary traffic and CPU load on cameras. It's a subtle win, not a headline feature, but it matters when you're running 30+ cameras on a shared fabric.
• 1RU Rack-Mount Form Factor: Fits any standard 19-inch cabinet. At 23.1 lbs, it's light enough for wall-mount brackets too (if your cabinet space is limited). No auxiliary cooling required — the switch runs passively in most data center or electrical closet environments.

Deployment Considerations:

• Single AC Power Inlet: Unlike enterprise switches with dual power supplies, the PPSW-1101 has one inlet. One breaker fault, one loose cord, or one power strip failure brings down all 24 ports. Mandatory: pair with a UPS (500VA minimum), and use a dedicated, labeled outlet on a separate circuit from lighting or HVAC. We've seen sites lose entire camera networks to accidental wall switch flips.
• Per-Port Power Ceiling of 95.44W: This is the 802.3at spec. If you have a single camera that draws 110W (some high-end PTZ with IR boost + heater), it won't negotiate and won't power on. Audit each camera's spec sheet before deployment. ACTi cameras are engineered to fit comfortably; third-party high-power models may not.
• Cascading Requires 802.1Q Trunking Knowledge: If you need more than 24 ports, you'll add a second PPSW-1101 and connect the two via 802.1Q trunk ports. This requires VLAN planning and per-switch configuration. If your team is new to VLANs, budget time for setup and testing before the site goes live.
• Firmware Updates Are ACTi-Gated: Unlike some managed switches with community-driven firmware, ACTi controls the release cycle. Check ACTi's support portal for firmware availability and security patches. If you need immediate vulnerability remediation, contact ACTi directly — there's no open-source alternative.
• No Redundant Power Supply Option: If uptime is critical (hospital, airport, banking), consider deploying two PPSW-1101s in a load-sharing or failover topology — not a standard feature, but achievable with network design. Alternatively, pair a single switch with a high-capacity UPS (1500VA+) to tolerate extended power loss.
• Port-by-Port Power Monitoring Is Basic: The web interface shows power draw per port, but alerting (e.g., "port 5 is approaching 90W") is limited. You'll need to monitor via SNMP integration with your NMS (network management system) or manual periodic checks if overload prevention is critical.

The PPSW-1101 is the right fit for integrators building mid-scale surveillance backbones on ACTi hardware or mixed-brand deployments where power-efficient cameras dominate. It's also a solid choice for clients with network-savvy IT teams who can manage VLAN and QoS configuration — the investment in managed switching upfront pays dividends in traffic isolation and troubleshooting during the 5–10 year lifecycle. Skip it if you have fewer than 8–10 cameras (a 4-port PoE injector is cheaper) or if you need true redundancy (dual-supply enterprise switches are your path). For the target use case, the PPSW-1101 delivers genuine TCO savings: no auxiliary power supplies, no separate patch panels, one firmware to track, one UPS to size.
