How to Connect the OREI HD-102 to Split a Camera's HDMI Signal

The short answer

A 1x2 HDMI splitter such as the OREI HD-102 takes one HDMI source and sends copies of it to two HDMI destinations. To split a camera's signal, run an HDMI cable from the camera's HDMI output to the splitter's input. Then connect each of the splitter's two outputs to a destination, for example a USB capture device for your computer and an external monitor. Power the splitter and switch on the camera. Both destinations should then receive the same picture.

The splitter does not turn a DSLR or mirrorless camera into a webcam. On most laptops and desktops, the HDMI port is an output only, so it cannot receive a camera feed. To use the camera in a video call, one splitter output has to go into an HDMI capture device. The capture device is what your computer recognizes as a camera.

Check which device you actually need. A splitter has one input and several outputs and sends one source to several screens. If you want to choose between two cameras feeding one computer, you need an HDMI switch instead. A splitter will not do that job.

What this guide could not confirm about the HD-102

No verified specifications for the HD-102 were available while writing this guide. The following details are therefore unconfirmed:

• How the splitter is powered
• Which resolutions and frame rates it supports
• Whether it passes audio
• How it handles two displays with different capabilities
• What its indicator lights mean

Check the manual, the product label or the port markings for these details. The steps below follow general HDMI principles that apply to 1x2 splitters.

What you need

• A camera with an HDMI output. Many cameras use a mini or micro HDMI port, so you may need a cable or adapter with that connector on the camera end.
• The OREI HD-102 and whatever power source came with it.
• One HDMI cable from the camera to the splitter input.
• Two HDMI cables from the splitter outputs to your destinations.
• An HDMI-to-USB capture device, if one destination is a computer.
• A way to keep the camera powered for long sessions, such as a spare battery or a dummy-battery power adapter, if your camera supports one.

Step-by-step setup

• 1. Prepare the camera. In its menus, find the HDMI settings. Turn off on-screen information so the output is clean, meaning it has no focus boxes, battery icons or menus. Choose an output resolution that both destinations can accept; 1080p is a widely supported choice. Disable auto power-off, because many cameras shut down after a few minutes and end your feed.
• 2. Identify the splitter's ports. Confirm which port is the input and which two are outputs from the labels on the unit. Plugging the camera into an output port is a common reason for getting no picture.
• 3. Connect the cables with everything switched off. Run the camera's HDMI output to the splitter input. Then run output 1 to the capture device and output 2 to the monitor.
• 4. Connect the capture device to the computer over USB.
• 5. Power the splitter using the method its manual describes.
• 6. Turn on the monitor, then the camera. Some cameras switch off their rear screen once an HDMI device is detected, which is normal.
• 7. Open a camera app on the computer and select the capture device as the video source.

How to verify each part works

"It works" can mean several separate things. Check each one in order so that you can locate the fault if something fails.

Check | What it tells you | How to confirm

Monitor shows the camera image | Camera, splitter input and one output are working | The live view appears on the monitor

Computer lists the capture device | The device is connected and detected | It appears in the camera list of your OS settings or camera app

App or browser is allowed to use it | Camera access is granted | No permission prompt is blocking it, and the device is enabled in OS privacy settings

Preview shows a live image | Video capture actually succeeds | A moving picture appears, not a black frame or a still frame

Test call looks acceptable | Call quality is usable | Ask someone to confirm sharpness and smoothness, or record a test meeting

Passing one check does not guarantee the next. A capture device can be detected and permitted but still show a black frame if the camera is not sending a format the splitter or capture device accepts. A clean preview also does not guarantee good call quality, because the call service may compress the video depending on your connection.

Audio through the splitter

HDMI can carry audio, and some cameras send their microphone audio over HDMI. This guide could not confirm whether the HD-102 passes audio to both outputs. If you rely on camera audio, make three separate checks:

• Detection: the capture device appears as a microphone in your system's sound settings.
• Input activity: the level meter moves when you speak.
• Intelligibility: a test recording sounds clear and stays in sync with your lips.

Many people avoid audio routing problems by plugging a separate USB microphone or headset directly into the computer.

If something doesn't work

• No picture anywhere: confirm the camera is in the input port, the splitter has power, and the camera's HDMI output is enabled. Then connect the camera directly to the monitor, bypassing the splitter, to find out which link is failing.
• Picture on one output but not the other: swap the two output cables. If the problem follows the cable, replace the cable. If it stays with the port, the issue is that output or the device attached to it.
• The monitor works but the computer shows black: lower the camera's HDMI output to a common resolution such as 1080p. Close other apps that may already be using the capture device. Also recheck camera permissions for your browser or call app.
• Resolution looks lower than expected: when two destinations differ in capability, a splitter may send a format both can display. Check the manual for how the HD-102 handles this.
• On-screen icons appear in the call: turn off the information display in the camera's HDMI settings. The exact option name varies by camera model.
• The feed stops after a while: check the camera's auto power-off, overheating warnings and battery level.
• The image is mirrored or flipped in the call: this is usually a self-view setting in the call app, not a splitter problem. Other participants normally see the unmirrored image.

Next step

Once both outputs show a stable picture and a test call looks right, lock in the camera's HDMI settings. If your model supports custom setting profiles, save them as one. Then you can rebuild the same setup quickly next time. If problems continue, check the HD-102 manual for its supported formats and power requirements, since this guide could not confirm them.
