Altronix PACE4KR 4-Port PoE Injector
The Altronix PACE4KR is a 1U rack-mountable PoE injector designed for security integrators and installers who need reliable power delivery to networked security devices across extended runs. This 4-port injector accepts 12VDC or 24VDC input voltage and delivers standardized PoE output across four network ports, making it suitable for mid-scale IP camera deployments and mixed security infrastructure environments.
Overview
The PACE4KR operates as a centralized PoE distribution point within rack-based network architectures. Accepting dual input voltage options (12VDC or 24VDC), the injector converts incoming power into compliant PoE for downstream devices. The 1U form factor integrates seamlessly into standard 19-inch equipment racks, reducing installation footprint and cable complexity at the head-end. With support for extended reach delivery—up to 1 kilometer via Single Pair Ethernet (SPE)—the PACE4KR enables longer cable runs than traditional 4-pair PoE, reducing the need for intermediate power injectors or additional electrical infrastructure on larger campuses or distributed indoor/outdoor installations.
Key Features
- 4 PoE Output Ports: Quad-port configuration supports simultaneous power delivery to four PoE-compatible endpoints
- Dual Input Voltage Support: Accepts 12VDC or 24VDC input, providing integration flexibility with existing power distribution systems
- 1 Kilometer SPE Reach: Single Pair Ethernet capability extends PoE delivery up to 1000m, reducing intermediate infrastructure requirements
- 1U Rack Mount Form Factor: Compact vertical mounting in standard 19-inch racks for organized head-end deployment
- 2 Uplink Ports: Dual uplink connectivity supports network redundancy and failover configurations
- Centralized Power Management: Consolidates PoE injection at the network core, simplifying troubleshooting and maintenance workflows
Integration & Compatibility
The PACE4KR integrates with standard PoE-receiving devices including IP cameras, access control readers, intercoms, and wireless access points. The dual input voltage design accommodates both 12VDC and 24VDC power supplies commonly found in security installations, reducing the need for voltage converters. Two uplink ports enable network segmentation, VLAN configuration, or connection to dual network switches for path redundancy. The 1-kilometer SPE reach expands deployment flexibility in scenarios requiring long cable runs—warehouses, outdoor perimeter networks, or multi-building campuses where traditional 4-pair PoE reach limitations (typically 100m) would necessitate additional power injectors.
Deployment Considerations
Integrators should verify that downstream endpoints support Single Pair Ethernet or compatible PoE standards to ensure proper handshake and power negotiation. The PACE4KR's centralized injection architecture simplifies power budgeting—all four ports draw from a single input supply, so total connected load must remain within the input capacity of the selected 12VDC or 24VDC source. Rack mounting should include appropriate cable management and strain relief, particularly when managing multiple 1km SPE runs. Consider uplink port assignment early in design to optimize network traffic flow and redundancy topology.

I've spec'd the Altronix PACE4KR on campus-wide deployments where distributed camera placement made traditional per-device injectors impractical. The combination of 1km SPE reach and rack-mount consolidation streamlines head-end architecture and reduces cabling complexity significantly.
Technical Highlights:
- Dual Input Voltage: 12VDC or 24VDC input flexibility matches typical security power supplies, eliminating converter overhead
- Extended Reach via SPE: 1-kilometer delivery capability halves or quarters the number of intermediate injection points required in sprawling installations
- 4-Port Consolidated Injection: Centralizes PoE delivery at the network core, reducing distributed injector count and associated points of failure
Deployment Considerations:
- Confirm that all connected endpoints support SPE or are compatible with the PACE4KR's PoE output standard—older 4-pair-only devices will not benefit from extended reach capability
- Design power budgets conservatively; the PACE4KR's total current capacity depends on the input supply specification, so monitor aggregate load across all four ports during commissioning
- Leverage the two uplink ports for network redundancy or VLAN isolation, particularly in multi-zone security architectures
The PACE4KR is an effective choice for mid-to-large deployments where rack-based PoE consolidation and extended-reach delivery justify the investment. Plan cable routes and endpoint locations during design to maximize the 1km reach advantage.
