POE Ethernet-Over-Coax Adapter Kit (DECA-200) - Twin Pack

In this review the Dualcomm POE Ethernet-Over-Coax Adapter Kit (DECA-200) is examined for installers who need to extend both power and 10/100Base-T network data over existing coax cabling. The bottom line: this twin pack is best for technicians and users who want a straightforward way to connect an IP camera or other Powered Device to a PoE switch without re-running Ethernet cable. The kit includes a pair of matched adapters that create an end-to-end PoE link over coax, and the simplicity of installation is the single biggest reason many buyers will choose it.

Key Features

• Twin adapter kit: Includes DECA-200A and DECA-200B so a single purchase provides both ends needed to pass Ethernet and PoE over one coax run.
• PoE support: Supports PoE power delivery compatible with 802.3af/at standards at the Powered Device end, enabling plug-and-play power for cameras and other PDs.
• 10/100Base-T data: Transmits full-duplex Ethernet at 10/100 speeds over coax, preserving standard network connectivity while avoiding cable replacement.
• Mode-specific connection: DECA-200A is intended for connecting to the PSE Mode A port while either adapter can connect to the PD, simplifying proper installation.
• Compact design: Small adapters are easy to mount near equipment or inside enclosures, which helps maintain a tidy installation.

Who It's For

This kit is aimed at CCTV installers, property managers, and IT technicians who need to reuse existing coax runs to deliver both power and network data to remote devices such as IP cameras. It is especially useful where running new Ethernet cable would be costly or disruptive.

It is not the best choice for users who require gigabit throughput or have coax that is damaged or nonstandard; those projects are better served by new Cat5e/Cat6 cabling or solutions specifically rated for higher than 100 Mbps.

Pros & Cons

Pros

• Delivers both PoE and 10/100Base-T Ethernet over a single coax run, reducing cabling work.
• Includes a matched pair so installers have the required PSE and PD endpoints in one kit.
• Easy to install with a compact, unobtrusive form factor suitable near cameras and switches.
• Compatible with standard PoE 802.3af/at devices when connected correctly to Mode A.

Cons

• Data rates are limited to 10/100Base-T; this is not a gigabit solution and may bottleneck high-bandwidth devices.
• Some customers report mixed compatibility results on certain installations, so pre-deployment testing is recommended.

Our Verdict

The DECA-200 twin pack is a practical, costeffective tool for reusing coax to deliver both power and network data to IP cameras and similar devices. Installers who need a simple way to avoid re-cabling will find it good value, provided they accept the 10/100 speed limit and verify compatibility on their specific equipment.

Frequently Asked Questions

Can these adapters power an IP camera?
Yes; the kit passes PoE power to the Powered Device and supports PoE standards 802.3af/at when connected as directed.

Do they provide gigabit Ethernet?
No; the adapters transmit full-duplex 10/100Base-T Ethernet over coax and are not designed for gigabit throughput.

Which adapter connects to the PoE switch?
DECA-200A should be used to connect to the Power Source Equipment (PSE) in Mode A, while either unit can be used at the Powered Device end.
