RASPBERRY PI CAMERA TRIGGER
Capture what happens
when you’re not watching.
Automate your camera’s shutter for time-lapse photography and long-duration projects.
more than an intervalometer
A camera trigger with a computer behind it.
An intervalometer controls when your camera takes a picture. A Raspberry Pi can do much more.
Schedule photographs for a specific time of day, respond to events, or build your own automated photography workflow. The Camera Trigger provides the simple hardware connection between your Raspberry Pi and your camera.
Using a mini computer like a Raspberry Pi unlocks new possibilities. Program it to take photos at a certain time of day—down to the second. Or trigger the camera based on an event, sensor, or condition in your photography setup.
TIME-LAPSE PHOTOGRAPHY
Turn time into a photograph.
Some things happen too slowly to see.
The movement of stars across the sky. The changing light of a sunset. A building taking shape. A plant growing day by day, or a flower opening up.
The Corona Designs Camera Trigger gives your Raspberry Pi control of your camera’s shutter, making it possible to automate photographs over hours, days, weeks, or longer.
Broad COMPATIBILITY
Works with digital and film cameras.
The Camera Trigger operates the camera’s shutter circuit just like a conventional wired remote. No USB camera control or Wi-Fi connection is required.
made for photographers
More control.
More possibilities.
We designed the Camera Trigger for photographers who want to go beyond the limitations of a conventional intervalometer. Precise timing, programmable automation, and the flexibility of a Raspberry Pi open up new possibilities for time-lapse photography.

why use a raspberry pi?
Your Camera.
Your Timing.
Your Rules.
Precise Timing
Trigger your camera at exactly the intervals you specify.
Time-based automation
Start shooting at sunset, sunrise, midnight, or any other time.
Event-based triggering
Have your camera respond to something happening elsewhere in your project.
Build your own workflow
Because the trigger is controlled by a Raspberry Pi, you can build photography workflows that go beyond the functions of a conventional intervalometer.
Design Features
Simple where it matters.
Connect your camera to the trigger using a 3.5mm TRS connection. The Camera Trigger operates your camera’s shutter by electrically closing the same circuit used by a wired remote shutter release.
Your camera may require a camera-specific cable or adapter.
Small yet mighty.
At only 34.5 × 14 × 12 mm, the Camera Trigger is small enough to disappear into your camera rig—and even fits inside many Raspberry Pi cases.
Safe by design.
The trigger uses optical isolation to keep your camera and the Raspberry Pi electrically separated. The circuitry provides up to 5,000 V of electrical isolation, helping protect your camera from electrical faults on the Raspberry Pi side.
