Record trail cam videos automatically on movement using a Raspberry Pi
Once logged into your rpi, clone the repo - it can be wherever you like, but assuming you set this up in /home/pi:
git clone https://github.com/amnuts/trailcam.git
cd trailcam
In the trailcam directory you'll see a config.json file that looks like:
{
"pir_pin": 14,
"save_path": "/home/pi/Videos/trail-%s.h264",
"delay_start_seconds": 30,
"sleep_seconds": 2,
"record_seconds": 10,
"debug_output": false
}
The pir_bin define what pin the PIR sensor data output is attached to. Bear in mind that this is BCM numbering, but https://pinout.xyz/ is a great site to see what pins are what.
The delay_start_seconds is how long it'll take to start recording from when the script starts - handy if you have it auto-start on the pi booting up.
The record_seconds is how long the video should keep recording for once it doesn't detect any movement.
sleep_seconds is how long it'll sleep before running the recording check loop again.
The save_path is where it'll save the file. The %s will be substituted with the current date and time of when the video was recorded. So if you want the actual date/time then you'll either need an internet connection or a real-time clock module for the rpi.
If you wish to have the script run automatically when you boot the rpi, you can edit the /etc/rc.local file and add the following line:
(su - pi -c "python /home/pi/trailcam/record.py")&
