Grid IP/PoE over Coax & 2-Wire Extender | 100 Mbps up to 500 m / 1,640 ft Retrofit Ethernet | POEJK-2WIRE

Overview

The POEJK-2WIRE is a compact IP / PoE extender that pushes 10/100 Mbps Ethernet data and 802.3af/at PoE over existing 2-wire copper or coax. It’s designed for retrofit projects where you want to get an IP camera, intercom, access point or PoE-powered device to a location that only has legacy cabling—without opening walls to pull new Cat6.

Each link uses a pair of POEJK-2WIRE units (one at the network/PoE side and one at the remote device side). With suitable copper, you can reach up to 500 m / 1,640 ft and still deliver PoE power up to 30 W to the far end.

If you’re searching for an IP-over-coax or IP-over-2-wire PoE extender for long runs in Canadian buildings, POEJK-2WIRE is the GRID ecosystem answer.

Key features

• 10/100 Mbps Ethernet over 2-wire or coax – extends 10/100 Mbps data plus PoE/PoE+ over legacy copper.
• PoE / PoE+ support – passes 802.3af/at power with up to 30 W max PoE to the remote device (within distance and cable limits).
• Long-reach extension – up to 500 m / 1,640 ft on suitable 2-core pure copper pair or copper coaxial cable.
• Two-wire or coax options – use BNC for coax or the 2 × 3.81 mm Phoenix terminal for 2-wire twisted pair.
• Pair-based design – devices are used in pairs; one unit at the PoE switch side, one at the remote device.
• Flexible power input – can be powered from upstream PoE or via external DC 44–57 V power supplies when PoE isn’t available (power supplies not included).
• Point-to-point simplicity – ideal for single camera, door controller or POE-Jack® runs over existing copper.

Technical highlights

Ideal applications

• Reusing existing coax or 2-wire from old analog cameras to carry IP cameras and PoE.
• Upgrading door phones, gates and intercoms in older Canadian buildings where only 2-wire is present.
• Running PoE to garages, barns, sheds or outbuildings using spare low-voltage pairs or coax.
• Renovations where opening finished walls or core drilling for new conduit would be costly.

Compatibility & ecosystem

POEJK-2WIRE is designed to work alongside GRID PoE switches and Active POE-Jack® deployments as a long-reach “bridge” where Cat6 isn’t practical. One unit lives near the PoE switch, the other near the remote IP device or POE-Jack® node.

The extender simply presents regular RJ45 Ethernet + PoE at each end, so it is compatible with IP cameras, access control panels, small PoE switches, POE-Jack® in-wall switches and other standards-based powered devices.

Install & design notes

• Always use pairs of POEJK-2WIRE units on each extended link (head-end and remote).
• Verify that the existing copper is pure copper (not copper-clad steel or aluminum) and in good condition.
• Use dedicated pairs or coax runs; avoid sharing conductors with other systems.
• At long distances, treat 30 W as an upper bound—real-world available power at the far end will depend on cable gauge and condition.
• If upstream PoE is not available, budget for DC 44–57 V power supplies at the appropriate end(s).

Canada-ready checklist

• ✓ Ideal for Canadian retrofits where running new Cat6 is difficult (heritage buildings, condos, farm structures).
• ✓ Works with typical RG59/RG62 coax and 2-wire low-voltage pairs found in older camera and doorbell installs.
• ✓ Helps extend PoE into unconditioned spaces like detached garages (within product temperature limits and code).
• ✓ Reduces unnecessary demolition and patching in finished basements and suites.

Compatibility micro Q&A

Can I get Gigabit over POEJK-2WIRE?
No. POEJK-2WIRE is designed for 10/100 Mbps Ethernet. In most IP camera and access control applications, 100 Mbps is more than sufficient.

Do I have to use coax, or can I use any 2-wire?
You can use either 2-core pure copper wire or copper coaxial cable. Avoid copper-clad conductors, alarm wire with very small gauge, or mixed conductors in the same sheath.

Can I use just one unit as an adapter?
No. Each link requires two POEJK-2WIRE units—one at each end of the legacy cable run.
