Solving camera connection problems

Why doesn't my camera connect to Breeze software?

September 2021

Working out why your camera won’t connect to the program can be difficult and frustrating experience.

This  page lists common causes of camera connection problems and explains how to solve them. It has been written for the three Breeze software programs below. You may also find this page useful  when troubleshooting camera connection issues with other apps.

  • Breeze Booth (DSLR+Windows) aka DSLR Remote Pro
  • Breeze Multi-Camera
  • Breeze Flipbook

Work through the checklist below systematically to get your camera running successfully.

1.Start with the basics

How do I know whether my camera is connected to a Breeze program?

Breeze programs make it very clear when the program cannot connect to a camera. The three screenshots below show DSLR Remote Pro, Multi-Camera and Flipbook Photobooth when the program is not connected to a camera.

Breeze DSLR Remote Pro 3.15.4 displays a blue screen and clear messages showing that the camera is not connected to the program


Breeze Multi-Camera says ‘Not connected’ at the top of the screen. If you try to release the camera shutter Camera is not connected. Do you wish to reconnect? is displayed


If you try to start Breeze Flipbooth Photobooth without successfully connecting the camera, this screen is displayed with error message Camera not connected

Check the camera body

First half press the camera shutter – it may have gone to sleep.

Next check that

  • the camera is switched on
  • you have removed the lens cap
  • the battery is charged/power supply connected and switched on
  • the battery compartment door is closed ( whether the camera is powered by mains supply or battery)
  • the exposure mode dial on the camera is set to P, Tv, Av or M
  • WiFi is switched off in the camera

Check the cabling, USB connectors and hubs

Check every connection between camera and PC, and tighten any loose connections.

2.Is your camera supported by the program version you are running?

Older versions of Breeze software may not support recent camera models, and we are not able to support some very old cameras in recent releases. If you are not sure whether your camera is supported by the program version you are running

Check the program version

Start the program, select Help then About..

Check the version of any Breeze (Windows) software using Help then About..

Check whether your camera model is supported by this version of the program, either by

Checking in the manual included with the program

Breeze include a copy of the manual in the program download. Open this using Help then Contents. Cameras supported by this version of the program are listed on the first page

Or checking the release history

3. Windows can see the camera but the Breeze program does not connect

Only one app on a Windows PC can control the camera at any time. If Windows can see the camera but your Breeze program won’t connect to it, it is likely another program has taken control of the camera.

Canon EOS Utility

Do not install Canon EOS Utility on the PC if you are running any Breeze camera. If EOS Utility is already installed on the PC, you may need to uninstall it for Breeze to work.

Other programs which control the camera

Ensure no other programs which could control the camera are running. Take particular care if any other photo booth or tethered shooting applications are installed on the computer.

4. Camera connects intermittently, or works initially and then loses the connection

Camera connection problems which start and stop are almost always caused by faulty equipment. Any piece of equipment in your system could have intermittent problems or fail completely. Usually equipment issues are caused by power supplies and USB cables and connectors, so check these first.

Power supplies – especially third party power supplies

Third party power supplies often cause problems. We recommend using one supplied by Canon. To check your power supply

  • Either power the camera with the original Canon camery battery (check it is charged). If the camera connects your problem is probably caused by the power supply
  • Or swap out the camera supply – if possible for a Canon version

USB cables and connectors

Use the shortest possible good quality cable (the cable provided by Canon with each camera is ideal) and plug this directly into a USB port on the computer if possible.

  • USB standards state that cables should be no more than 5 metres long.
  • If you need to connect cables together externally powered hubs are generally more reliable  than active USB cables.
  • Keep the number of connections to a minimum

USB ports (where the cable connects to the PC and camera) can also fail, but this is much less common than the cable or connector failing.

If you cannot find any faults in the USB or power supply, you need to systematically swap out all other pieces of equipment one at a time until you find the fault. If necessary can download and run a trial version of the program on a different PC.

If all else fails

Try removing the power supply from the camera, then replace it

  • Mains power -switch the power supply off then on, or pull the connector out of the camera then replace it.
  • Battery power –remove and replace the camera battery

If you have worked thoroughly through this checklist you should find the problem before reaching this section. If all else fails drop us an email to You need to include

  1. program name and version (eg DSLR Remote Pro 3.15.5)
  2. camera model (eg Canon EOS 1200D)
  3. version of Window on the PC (eg Windows 10)
  4. your registration name and code (start the program, click on Help then Register to find this)
  5. screenshot(s) or clear JPEG photos showing your computer screen and any error messages. You may need to move error windows to one side so we can see all the information we need.

We will try to get you up and running again as soon as we can.
