Vaddio 451-0400-055 – PoE+ Midspan Power Injector

Product Overview

The Vaddio PoE+ Midspan Power Injector (451-0400-055) adds IEEE 802.3at Power over Ethernet Plus capability to any standard Ethernet cable run, enabling Vaddio cameras and interface devices to receive up to 30 watts of power without requiring a PoE-capable network switch. It is the ideal solution for commercial AV installations where the existing network infrastructure does not support PoE and a switch upgrade is not feasible. The injector passes data through transparently while injecting power on the unused pairs, preserving full network performance.

Product Description

The Vaddio PoE+ Midspan Power Injector 451-0400-055 is a single-port IEEE 802.3at compliant injector that delivers up to 30 watts of PoE+ power to connected Vaddio cameras and networked AV devices over a Cat-5e or Cat-6 Ethernet cable. In commercial AV projects, not every facility has PoE-capable network switches at every camera drop — this midspan injector bridges that gap without requiring network infrastructure changes.

Installation is straightforward: the injector connects between the non-PoE network switch port and the camera or interface device, inserting power onto the cable without altering data transmission. IEEE 802.3at compliance ensures the injector negotiates power delivery safely with the powered device, protecting equipment from overvoltage. At 30W output, the 451-0400-055 supports Vaddio's full range of PoE+-powered cameras and interface boxes.

For AV integrators specifying Vaddio camera systems in rooms with non-PoE switches, the 451-0400-055 provides a cost-effective, standards-compliant solution that avoids switch replacement or additional power supply runs. It is compact enough to mount in a rack or conceal above a ceiling tile near the camera drop point.

Key Features

• IEEE 802.3at PoE+ Compliance — Delivers up to 30W of Power over Ethernet Plus to connected Vaddio cameras and AV devices, meeting the full PoE+ standard.
• Single-Port Midspan Design — Adds PoE+ to any existing Ethernet run without replacing the network switch, protecting existing infrastructure investments.
• Transparent Data Pass-Through — Passes network data without alteration, maintaining full Gigabit or Fast Ethernet performance on the cable run.
• Broad Vaddio Device Compatibility — Powers Vaddio PoE+-compatible cameras, Quick-Connect interface boxes, and other 802.3at devices in commercial AV deployments.
• Compact Form Factor — Small footprint allows flexible placement in rack enclosures, above-ceiling locations, or equipment closets.
