It's quite simple, I started an age ago with building a camera from a pi-zero with a pi-cam (with the ir filter removed). Just find a dummy housing, like this one:
The install motion-eye (The instructions there are awesome) and you've got a security camera!
Next, wouldn't it be nice to alert you when it found something.. So I tried setting up motion-eye to trigger when it thought it saw something, but it was always giving me lots of false positives, for example when a cloud went overhead, a lot of pixels would change, then it would alert me.
Hmm not ideal, I wasn't that keen on having a cloud alerting function.
That's why I wrote the web service that you can find here on GitHub. So I set it up to email me when it detects. Even with that, I still got a lot of false object detections, so I modified the web service to have a filter and only filter if it spots one of the defined labels (- car - person - bicycle - motorcycle - cat - dog)
How?
Well setup motion-pi like so:
download the source code from git
modify the application properties for your setup (in src/main/rescources) and build it and run it
and now the detect script should look like:
You now should have a security camera that sends you an email if it spots any of the objected you setup in the spring properties file. The email should look like this

git clone https://github.com/stevegal/objectdetect_ws.git cd objectdetect_ws

mvn clean package java -jar target/objectdetect4j-0.1-SNAPSHOT.jar
and now the detect script should look like:
#!/bin/bash cdWORKING_DIR=$(ls -t | head -1) cd $WORKING_DIR for filename in *.jpg do curl -m 5 -F "image=@$filename" http:// : /detect/mailTo?mailTo= rm -f $filename done
You now should have a security camera that sends you an email if it spots any of the objected you setup in the spring properties file. The email should look like this
with a nice box around the things it has spotted. Works for me!
