How to Power a Z CAM E2-M4 Over Ethernet: A PoE Splitter Solution

For filmmakers and video professionals building compact camera rigs, simplifying power and network connections can make a setup easier to manage. A Power over Ethernet (PoE) solution can help reduce separate cable runs by carrying network data and power over a single Ethernet cable.

In this guide, we explain how a PoE splitter can be used to connect a Z CAM E2-M4 camera to both Ethernet data and a dedicated power connection.

What Is a PoE Splitter?

A PoE splitter separates the data and power carried over a compatible PoE Ethernet connection.

Instead of running a separate Ethernet cable and power cable all the way from the equipment rack, you can run one PoE Ethernet cable to the camera location and split the connection near the camera.

The two outputs serve different purposes:

• Ethernet output: Provides a network connection to the camera.
• DC power output: Supplies power through a compatible power connector.

For a Z CAM E2-M4 setup, the power output must be compatible with the camera's required voltage, connector, and polarity.

How the Setup Works

A typical configuration consists of a PoE-enabled network switch, a long Ethernet cable, a PoE splitter, and the camera.

Connection layout:

PoE Network Switch → Long Ethernet Cable → PoE Splitter → Ethernet Data + Camera Power

The Ethernet output connects to the camera's RJ45 network port. The power output connects to the camera's power input through a compatible two-pin connector.

This arrangement allows the network and power connections to branch off near the camera, without requiring a custom cable for the entire Ethernet run.

Why Use a Custom Two-Pin Power Output?

Many PoE splitters come with a standard DC barrel connector. However, camera equipment may use a different power connector.

A customized splitter can replace the original DC connector with a two-pin connector compatible with the Z CAM E2-M4.

Before use, the following specifications must be verified:

• Regulated 12V DC output.
• Correct two-pin connector type and mechanical fit.
• Correct positive and negative pinout.
• Adequate continuous output current and power capacity.
• Compatibility with the PoE switch and Ethernet data requirements.

Important: Connector shape alone does not establish polarity. Always verify the pinout before connecting power to the camera.

Is a 12V PoE Splitter Powerful Enough?

The answer depends on the camera's actual power consumption and the splitter's usable output capacity.

For example, a splitter rated at 12V and 2.5A has a nominal maximum output of 30W. Actual usable power may be lower because of conversion losses and operating conditions.

If the estimated camera power consumption is 10–15W, a splitter with approximately 25W of usable output capacity may be a reasonable option. However, the camera's actual maximum consumption should be verified before finalizing the setup.

For multi-camera installations, check both:

• Per-port PoE capacity: Each switch port must support the connected splitter's power requirements.
• Total PoE budget: The switch must supply all connected cameras simultaneously.

A higher-powered switch does not automatically increase the output capacity of an individual splitter.

Using PoE with Multiple Z CAM E2-M4 Cameras

For a three-camera setup, each camera typically needs its own PoE connection and splitter.

A simplified layout looks like this:

PoE Switch

• Port 1 → PoE Splitter → Z CAM E2-M4 Camera 1
• Port 2 → PoE Splitter → Z CAM E2-M4 Camera 2
• Port 3 → PoE Splitter → Z CAM E2-M4 Camera 3

Before installation, confirm that the switch supports the required PoE standard and has sufficient power available on each port and across the entire system.

A More Flexible Cable Setup for Camera Rigs

A short PoE breakout near the camera can be useful when the main Ethernet cable needs to run a longer distance.

Potential benefits include:

• One Ethernet run carrying both network data and PoE power.
• Separate network and power connections near the camera.
• Less need to run a separate power cable along the entire route.
• A customized two-pin power connector for compatible camera equipment.

The final design should be selected based on the camera's power requirements, connector specifications, network speed, and installation environment.
