Digital video recorder for Raspberry PI cameras with multi-camera synchronous acquisition.

Area of Science:

• Scientific Imaging
• Computational Biology
• Hardware Development

Background:

• Video acquisition and analysis are crucial in scientific research.
• While single-camera solutions exist, synchronized multi-camera acquisition systems, especially for prototyping, are less common.
• The Raspberry Pi (RPi) is a popular, cost-effective platform for research prototyping.

Purpose of the Study:

• To present an open-source digital video recorder (DVR) system for Raspberry Pi (RPi) cameras.
• To enable simple, synchronized multi-camera video acquisition and analysis.
• To provide a versatile tool for scientific research applications.

Main Methods:

• Development of an open-source digital video recorder (DVR) system using Python.
• Implementation of a graphical user interface (GUI) for camera preview, parameter setting, and naming.
• Ensuring synchronized acquisition for multi-camera setups.
• Demonstration of the DVR's utility in a life science application.

Main Results:

• A user-friendly, open-source DVR system for RPi cameras has been successfully developed.
• The system supports both single and synchronized multi-camera acquisition.
• The DVR includes GUIs for live preview, recording control, and video playback.
• The system demonstrated versatility in a high-throughput fruit-fly monitoring application.

Conclusions:

• The developed open-source DVR provides an accessible and effective solution for synchronized multi-camera video acquisition using Raspberry Pi.
• The system simplifies video data collection for various research fields, including life sciences.
• The Python-based DVR offers a flexible and cost-effective alternative to commercial systems.
