Camera Remote

Combining this program with a Raspberry Pi HQ camera, a Raspberry Pi Zero WH, and an Adafruit 16-LED NeoPixel ring will result in a camera that can be controlled via a web page.

Note

The primary intended use of this application is for still photography and photogammetry. Preview mayb be suspended during video capture due to apparent hardware limitations. This system can be used to capture video, but it currently is not user-friendly.*

Use With Other Camera Software

Optionally, this application may be used in conjunction with one of the following applications:

• Camera Zero: Camera Remote can be triggered by long-pressing the pale orange button for 5 - 9 seconds. You can switch back to trackball control from within Camera Remote.

---

Getting Started

• Use Raspberry Pi Imager to install Raspberry Pi OS Lite (Bookworm) on a microSD card
• Use raspi-config to:
  • Enable the CSI camera interface
  • Set up your WiFi connection
• Connect the Raspberry Pi HQ Camera to your Raspberry Pi

Installation

Installation of the program, any software prerequisites, as well as DNG support can be completed with the following two-line install script.

wget -q https://raw.githubusercontent.com/eat-sleep-code/camera.remote/main/install-camera.sh -O ~/install-camera.sh
sudo chmod +x ~/install-camera.sh && ~/install-camera.sh

Usage

camera.zero <options>

Options

• --rotate : Rotate the camera in 90° increments (default: 0)
• --exifFStop : Set the numeric F-Stop value in the image EXIF data (default: Not specified)
• --exifFocalLength : Set the numeric Focal Length value (mm) in the image EXIF data (default: Not specified)
• --exifFocalLengthEquivalent : Set the numeric 35mm Focal Length value (mm) in the image EXIF data (default: Not specified)

Example

camera.zero --rotate 180 --exifFStop 2.2 --exifFocalLength 2.75 --exifFocalLengthEquivalent 16

Tip

The EXIF data shown above is completely optional but may prove useful when using captured images with third-party applications such as photogrammetry software.

Footnotes

1. Due to licensing restrictions, video is captured with an .h264 format. To convert the .h264 file into the more common .mp4 format, you can execute the following command: ffmpeg -framerate 30 -i input.264 -c copy output.mp4 ↩
