Can I Use My Canon EOS Rebel T100 (4000D) As A Webcam?

How Do I Use My Canon EOS Rebel T100 as a Webcam?

To use your Canon EOS Rebel T100 (EOS 4000D) as a webcam you will need to:

1. Have the right USB cable – Canon IFC-400PCU

2. Have the Canon EOS Webcam Utility software

3. Have a compatible application to use such as Zoom, Skype or OBS Studio.

I guide you through each of the above requirements so you have everything you need to achieve high-quality video by using your Canon EOS Rebel T100 as a webcam for live streams or video calls.  

What USB Cable Do I Need to Use My Canon EOS Rebel T100 as a Webcam?

To use your Canon EOS Rebel T100 as a webcam you will need an IFC-400PCU cable. This is how you will connect your Canon Rebel T100 (EOS 4000D) to your computer.

Unfortunately, the IFC-400PCU cable is not included in the box when you buy the standard Canon EOS Rebel T100.

So to connect your Canon T100 to your computer you will have to get your own IFC-400PCU cable.

*For Mac Users:

You may need a USB-C to USB adapter to be able to plug your IFC-400PCU cable into your Mac.

I personally like to use a USB-C hub on my M1 Macbook Air 2020 because it gives me more options than just a standalone USB-C to USB adapter.

The reason for this is, your Mac device may not have a standard USB port (depends on the model you have) and might only have a USB-C port. 

In this case, you want to connect the IFC-400PCU cable to the adapter cable or hub, and then plug the adapter into your Mac.

What Canon Software Do I Need to Use My Canon EOS Rebel T100 as a Webcam?

You will need to download and install the latest Canon EOS Webcam Utility software. Here’s how to do that.

1. Go to the Canon support website for the EOS Webcam Utility software.

2. Scroll down to the section where it asks you to choose your camera model. You will want to choose the Canon EOS Rebel T100.

3. When you click on the Canon EOS Rebel T100 you should be taken to this page which is a support page for the Canon EOS Rebel T100.

4. Make sure you click on the ‘Software and Drivers’ tab and scroll down to the ‘Downloads‘ sections.

5. Choose the correct Windows or Mac operating system and version, it should default to the correct operating system as it normally detects this automatically.
   
   For example, if you are using Windows 10, then it will most likely detect ‘Windows 10’ or ‘Windows 10(x64)’.

6. Go down to the list of software and download the most recent version of ‘EOS Webcam Utility Pro’ (this used to be just called EOS Webcam Utility before November 2022) software for your operating system.
   
   Don’t get this confused with ‘EOS Utility’ which is different to ‘EOS Webcam Utility’.

7. Once it is downloaded, open up the downloaded file which should look similar to this ‘EOSWebcamUtilityPro-WIN2.0zip’. It might look slightly different depending on how recent your version is.

8. It should be saved as a ‘.zip’ file. Open and extract the .zip file. On Windows, you can normally do this by right-clicking and selecting ‘extract all’.

9. Read the ‘readme.txt’ file and run the ‘setup.exe’ file within the folder.

10. Follow the instructions that are shown until setup and installation is complete.

11. Once installation is complete you should restart your computer.

FAQS

What’s the Max Resolution on the Rebel T100 using Webcam Utility?

When using the updated Canon EOS Webcam Utility Pro there are different maximum resolutions depending on what version you have.

• If you are using the free version the max resolution is 720p (digitally upscaled)
• If you are using the paid subscription version, then the max resolution is 1080p (digitally upscaled).

I think the footage is digitally upscaled from a resolution of about 1024 x 576 because that’s what the max resolution was before the November 2022 update to the Utility.

Can I Use the Canon T100 as a webcam using HDMI output?

While you can technically use a capture card with the Rebel T100, it’s not recommended because there is no clean HDMI output on the Rebel T100 (EOS 4000D).

This means you’ll still see icons and overlays from the display like the autofocus box.

This is why I don’t recommend it and think the USB method of using the T100 is better.
