Introduction
Compatible with all Raspberry Pi boards, this camera module has a very good imaging effect both in day and night and works well in low-light environment without infrared fill light; if you are an animal lover, it is really appropriate to use it to record the animal activities at night, especially nocturnal animals like owls, lemurs, and cats.
This module uses Sony 1 / 2.8Inch 2MP STARVIS sensor IMX327 with focal length 4mm, and supports 1080p @ 30fps video. It comes with excellent built-in ISP function, and the output format is uncompressed UYVY, YUV 422-8 bit. In addition, it is also equipped with noise reduction and anti-fog functions to ensure that the captured picture is excellent in both color fidelity and image quality.
This module adopts universal CSI interface, and connects to Raspberry Pi through cable. It also supports adjustable brightness, contrast, sharpness, and saturation, making the output image extremely clear. The camera module can be well suitable for machine vision, intelligent analysis, industrial control, face recognition, ADAS and other fields.

Installation and configuration of Raspberry Pi
More detailed information about Raspberry Pi installation, refer to Guide for Installing Raspberry Pi
Power on the board to start the Raspberry Pi system. The camera and I2C are both disabled in initial Raspberry Pi system, and we have to enable them manually. Run the command:
| sudo raspi-config |
Enter option 5, enable Camera and I2C, and restart.
It is recommended to enable ssh and samba service on the Raspberry Pi. You can Google to find out how to enable them.
Software Package Download and Introduction
Two ways to download and transfer software packages into Raspberry Pi
- Execute the command line
git clone https://github.com/veyeimaging/raspberrypi.git
Directly copy the files into Raspberry Pi System.
- Click the link to download the software package
Transfer the software package into the Rasbperry Pi system via samba or use a U disk to copy the package file into it.
Software Introduction
- The software package includes video streaming and video control software package. i2c_cmd is the video control interface software package. There are two software packages for the video streaming interface: veye_raspcam is raspcam type toolkit, and D_mipi_rpi is D-SDK software package that provides SDK in c and contains demo in c and python.
- The video stream software package offers real-time display, capture, video recording and other functions. The video control software package controls the camera module via I2C, and provides the main ISP parameter configuration and other functions.
Both parts are open source.
How to use video stream software package
raspicam type toolkit
To begin with, add the executable permissions.
| cd raspberrypi/veye_raspcam/bin/ |
| chmod +x * |
- veye_raspipreview
| ./veye_raspipreview -t 20000 -p '0,0,1280,720' |
Realize the real-time display of 20s (20000 MS) video to HDMI output. The output window is 1280 * 720. The size of T and output window can be adjusted.
| ./veye_raspipreview -t -1 |
By adjusting t to - 1, the video output can be continuously displayed to HDMI output and displayed in full screen.
- veye_raspivid Video Recording
| ./veye_raspivid -t 5000 -o ~/test.h264 |
Realize video recording for 5s, and save the recording files to ~/test.h264. Adjust the size of t to select the recording time. Meanwhile, realize the real-time video display to HDMI output. (If preview function is not needed, you can add -n function.)
- veye_raspivid network transmission (direct tcp stream with netcat)
Execution on Rasbpberry Pi
| ./veye_raspivid -b 4000000 -t 0 -o - | nc -l -p 5000 |
