PoE Ethernet Splitter 4 Pair RJ45 Cable Sharing Kit - Dual Camera

In this review the PoE Ethernet Splitter 4 Pair RJ45 Cable Sharing Kit is evaluated for installers who need to run two 10/100 Mbps devices over a single Cat5e/6 run. The bottom line: it is a practical, cost-saving tool for security camera setups and other small-network extensions because it reliably combines and separates two Ethernet lines and includes a built-in RJ45-female adapter for easier connections. The reviewer found it saves cable runs and installation time while remaining simple to fit into existing surveillance systems.

Key Features

• Dual-line over one cable: Sends two separate 10/100 Mbps data lines over a single Cat5e/6 cable so two cameras or devices can share one run without complex rewiring.
• 2-in-1 combiner and splitter: Connects two switch ports to a single combiner and then separates signals at the device end to reduce the number of conduit runs and wall penetrations.
• Built-in RJ45-female adapter: The upgraded splitter end includes a female port that makes extension and swapping devices easier and more secure during installation.
• Weatherproof accessories: The kit includes waterproof self-fusing butyl tape for outdoor use, helping seal connections at exposed junctions.
• Wide compatibility: Works with standard PoE and non-PoE 10/100 Mbps surveillance cameras, NVR systems, injectors and switches for flexible deployment.
• Local support and warranty: Backed by a two-year quality warranty with local replacement service and 24/7 technical support for peace of mind.

Who It's For

This kit is aimed at surveillance installers, small business owners, and DIYers who want to run two IP cameras or two network devices where running separate cables is difficult or expensive. It's especially useful for camera clusters, long-distance runs where conduit is limited, or retrofits where adding new runs would disturb finishes.

It is not intended for gigabit backbone links or network segments that require PoE+ or higher power delivery; users who need multi-gigabit speeds, power-hungry devices, or advanced managed switch features should look for a full PoE switch or fiber solution instead.

Pros & Cons

Pros

• Saves on cable and installation time by combining two 10/100 Mbps lines onto one Cat5e/6 run.
• Upgraded splitter with a built-in RJ45-female adapter simplifies device swaps and extensions.
• Includes waterproof self-fusing butyl tape for protecting outdoor terminations.

Cons

• Limited to 10/100 Mbps speeds, so it is not suitable for gigabit-only devices or high-bandwidth camera streams.
• Does not change PoE power class limitations, so very high-power PoE devices may not be supported.

Our Verdict

The PoE Ethernet Splitter 4 Pair RJ45 Cable Sharing Kit is a sensible, budget-friendly choice for installers who need to run two 10/100 Mbps cameras or devices over a single cable. Its built-in RJ45-female adapter and weatherproofing make field work easier, and the two-year warranty adds security. Avoid it only if you require gigabit speeds or high-power PoE for demanding devices.

Frequently Asked Questions

Can I use this with PoE cameras?
Yes, it is compatible with standard PoE and non-PoE 10/100 Mbps cameras, but it is not intended for higher-power PoE+ or multi-gigabit devices.

Do I still need tape or sealant for outdoor installs?
The kit includes waterproof self-fusing butyl tape to protect exposed terminations, which is recommended for outdoor use.

Will this give me gigabit speeds?
No, the splitter and combiner operate at 10/100 Mbps and are not suitable for gigabit links.
