Speco Technologies POESPL PoE Splitter
Overview
The Speco Technologies POESPL is a single-source PoE splitter designed to extend Power over Ethernet infrastructure to devices requiring 12V DC input. This adapter bridges the gap between modern PoE networks and legacy security equipment, access control systems, and other DC-powered devices. By accepting 802.3at (PoE+) and 802.3af power input, the POESPL converts wired PoE voltage to standard 12V DC output, enabling one-to-one device provisioning without additional power supplies or infrastructure modification.
Key Features
- 802.3at/af PoE Compatibility: Accepts both PoE+ (15.4W–30W) and standard PoE (3W–15.4W) input from compliant switches and injectors
- 12V DC Output: Regulated output supplies power to legacy devices, outdoor access control, and intercom systems without requiring separate AC adapters
- Wired Connectivity: Connects directly to Ethernet source for seamless integration into existing IP security networks
- Single-Source Design: One PoE input supports one powered device, simplifying installation and troubleshooting in distributed deployments
- Compact Form Factor: Minimal footprint suitable for wall-mount, rack-adjacent, or field installation near powered endpoints
- Power Type Flexibility: Supports both PoE+ and DC 12V operation modes, allowing mixed infrastructure deployments
Integration & Compatibility
The POESPL integrates with any IEEE 802.3at or 802.3af compliant PoE source, including managed switches with PoE ports, PoE injectors, and midspan devices. Ideal for powering IP intercoms, access control readers, outdoor siren modules, and legacy analog devices equipped with 12V DC connectors. Installation requires only an Ethernet cable from the PoE source to the splitter input; output power connects directly to the target device via standard DC barrel connector or terminal block, depending on device interface. No configuration required—the POESPL operates as a passive power converter, preserving network data integrity while supplying DC power.
Use Cases
Common deployments include retrofitting older security installations to PoE-powered networks, powering outdoor gate operators and access control systems from building switches, extending power to remote intercom stations without running separate 12V cabling, and supplying emergency power to area lighting and strobe modules in hybrid video surveillance systems. The POESPL eliminates the need for local power supplies at each endpoint, reducing installation cost and simplifying maintenance in multi-device sites.

I've evaluated the Speco POESPL during network upgrades for several mixed-age security installations. This splitter solves a real problem: when you're moving to PoE infrastructure but still have legacy 12V devices in the field, the POESPL provides a straightforward power conversion without dual-supply complexity. The single-source architecture keeps things simple and deployment-predictable.
Technical Highlights:
- PoE+ Input Acceptance: Accepts 802.3at (PoE+) and 802.3af power, giving you flexibility with older and newer switch infrastructure
- Regulated 12V DC Output: Delivers stable DC voltage to devices requiring standard barrel connectors or screw terminals, eliminating the need for separate wall-mount power supplies
Deployment Considerations:
- Verify the powered device's current draw matches the PoE source's available wattage; 802.3af supplies up to 15.4W, while 802.3at supplies up to 30W—confirm this before ordering if devices are power-hungry
- Place the splitter close to the powered device to minimize DC voltage drop over long runs; if the device is more than 50 feet away, consider the conductor gauge of your power cable
- In outdoor or high-moisture environments, ensure the splitter enclosure and connectors are protected with appropriate conduit or weatherproof housing
The POESPL is a reliable, low-cost tool for bridging legacy systems into modern PoE networks. It removes the need for redundant power infrastructure while keeping installation footprint minimal. Recommended for integrators managing multi-site access control and intercom retrofits.
