Speed-cam.py ver 11.26 will now run under the latest Raspberry Pi OS Bullseye with a pi camera module as well as webcam and IP cameras. For picamera support Run sudo raspi-config, Interface Options, then enable Legacy Camera option and reboot.
IMPORTANT - A raspbian sudo apt-get update and sudo apt-get upgrade will
NOT be performed as part of
speed-install.sh so it is highly recommended you run these prior to install
to ensure your system is up-to-date.
Step 1 With mouse left button highlight curl command in code box below. Right click mouse in highlighted area and Copy.
Step 2 On RPI putty SSH or terminal session right click, select paste then Enter to download and run script.
curl -L https://raw.github.com/pageauc/speed-camera/master/speed-install.sh | bash
This will download and run the speed-install.sh script. If running under python3 you will need opencv3 installed. See my Github menu driven compile opencv3 from source project
IMPORTANT speed-cam.py ver 8.x or greater Requires Updated config.py and plugins.
cd ~/speed-camera
cp config.py config.py.bak
cp config.py.new config.py
To replace plugins rename (or delete) plugins folder per below
cd ~/speed-camera
mv plugins pluginsold # renames plugins folder
rm -r plugins # deletes plugins folder
Then run menubox.sh UPGRADE menu pick.

This is a raspberry pi, Windows, Unix Distro computer openCV object speed camera demo program. It is written in python and uses openCV to detect and track the x,y coordinates of the largest moving object in the camera view above a minimum pixel area.
User variables are stored in the config.py file. Motion detection is restricted between y_upper, y_lower, x_left, x_right variables (road or area of interest). Auto calculated but can be overridden in config.py by uncommenting desired variable settings. Motion Tracking is controlled by the track_counter variable in config.py. This sets the number of track events and the track length in pixels. This may need to be tuned for camera view, cpu speed, etc. Speed is calculated based on cal_obj_px and cal_obj_mm variables for L2R and R2L motion direction. A video stream frame image will be captured and saved in media/images dated subfolders (optional) per variable imageSubDirMaxFiles = 2000 For variable settings details see config.py file.
If log_data_to_CSV = True then a speed-cam.csv file will be created/updated with event data stored in CSV (Comma Separated Values) format. This can be imported into a spreadsheet, database, Etc program for further processing. Release 8.9 adds a sqlite3 database to store speed data. Default is data/speed_cam.db with data in the speed table. Database setting can be managed from config.py. Database is automatically created from config.py settings. For more details see How to Manage Sqlite3 Database
- menubox.sh script is a whiptail menu system to allow easier management of program settings and operation.
- webserver.py Allows viewing images and/or data from a web browser (see config.py for webserver settings) To implement webserver3.py copy webserver3.py to webserver.py Note and update will undo this change.
- rclone Manage settings and setup for optional remote file sync to a remote storage service like google drive, DropBox and many others.
- watch-app.sh for administration of settings from a remote storage service. Plus application monitoring.
- sql-make-graph-count-totals.py Query sqlite database and Generate one or more matplotlib graph images and save to media/graphs folder. Graphs display counts by hour, day or month for specfied previous days and speed over. Multiple reports can be managed from the config.py GRAPH_RUN_LIST variable under matplotlib image settings section.
- sql-make-graph-speed-ave.py Query sqlite database and Generate one or more matplotlib graph images and save to media/graphs folder. Graphs display Average Speed by hour, day or month for specfied previous days and speed over. Multiple reports can be managed from the config.py GRAPH_RUN_LIST variable under matplotlib image settings section.
- sql-speed_gt.py Query sqlite database and Generate html formatted report with links to images and save to media/reports folder. Can accept parameters or will prompt user if run from console with no parameters
- makehtml.py Creates html files that combine csv and image data for easier viewing from a web browser and saved to media/html folder.
- speed-search.py allows searching for similar target object images using opencv template matching. Results save to media/search folder.
- alpr-speed.py This is a demo that processes existing speed camera images with a front or back view of vehicle using OPENALPR License plate reader. Output is saved to media/alpr folder. For installation, Settings and Run details see ALPR Wiki Documentaion

Raspberry Pi computer and a RPI camera module installed
or USB Camera plugged in. Make sure hardware is tested and works. Most RPI models will work OK.
A quad core RPI will greatly improve performance due to threading. A recent version of
Raspbian operating system is Recommended.
or
MS Windows or Unix distro computer with a USB Web Camera plugged in and a
recent version of python installed
For Details See Wiki details.
It is recommended you upgrade to OpenCV version 3.x.x For Easy compile of opencv 3.4.2 from source See https://github.com/pageauc/opencv3-setup
For Windows or Unix computer platforms (non RPI or Debian) ensure you have the most up-to-date python version. For Download and Install python and Opencv
The latest python versions includes numpy and recent opencv version that is required to run this code. You will also need a USB web cam installed and working. To install this program access the GitHub project page at https://github.com/pageauc/speed-camera Select the green Clone or download button. The files will be cloned or zipped to a speed-camera folder. You can run the code from python IDLE application (recommended), GUI desktop or command prompt terminal window. Note bash .sh shell scripts will not work with windows unless special support for bash is installed for windows Eg http://win-bash.sourceforge.net/ http://www.cygwin.com/ Note: I have Not tested these.
speed camera supports a docker installation on
Apple Macintosh per System requirements and Instructions
and
Microsoft Windows 10/11 64 bit with BIOS Virtualization enabled
and Microsoft Windows Subsystem for Linux WSL 2
per System requirements and Instructions.
- Download and install Docker Desktop for your System
- Clone the GitHub Speed Camera repository using green Clone button (top right)
- Run docker-compose up from the directory you cloned the repo into.
- The Docker container will likely exit because it is using a default config.
- Edit the configuration file @
config/config.py - Run docker-compose up per documentation
- Run docker build command locally to get a fresh image.
From logged in RPI SSH session or console terminal perform the following. Allows you to review install code before running
cd ~
wget https://raw.github.com/pageauc/speed-camera/master/speed-install.sh
more speed-install.sh # You can review code if you wish
chmod +x speed-install.sh
./speed-install.sh # runs install script.
cd ~/speed-camera
./speed-cam.py
See How to Run speed-cam.py wiki section
IMPORTANT Speed Camera will start in calibrate = True Mode.
Review settings in config.py file and edit variables with nano as required.
You will need to perform a calibration to set the correct value for config.py cal_obj_px and cal_obj_mm for
L2R and R2L directions. The variables are based on the distance from camera to objects being measured for speed.
See Calibration Procedure for more details.
The config.py motion tracking variable called track_counter = can be adjusted for your system and opencv version. Default is 5 but a quad core RPI3 and latest opencv version eg 3.4.2 can be 10-15 or possibly greater. This will require monitoring the verbose log messages in order to fine tune.
cd ~/speed-camera
./menubox.sh
Admin speed-cam Easier using menubox.sh (Once calibrated and/or testing complete)
View speed-cam data and trends from web browser per sample screen shots. These can be generated from Menubox.sh menu pick or by running scripts from console or via crontab schedule.
You can view recent or historical images directly from the speed web browser page. These are dynamically created
and show up-to-date images. Press the web page refesh button to update display
