After looking far and wide, we developed NetThermal, a tiny, DIY, WiFi-enabled thermal camera, and what's best - you can build one too!

Assembly

Initial Software Setup - MJPG-Streamer

• Connect to your Onion's WiFi network. It will be named something like Omega-XXXX
• Complete the setup at 192.168.3.1 (username: root, password: onioneer)
• Install the legacy console.
• From the legacy console, install the Webcam module.
• Go to the Terminal and type:

vi /etc/config/mjpg-streamer

• Make sure the file looks like this:

config mjpg-streamer 'core'
   option enabled '1'
   option input 'uvc'
   option output 'http'
   option device '/dev/video0'
   option resolution '160x120'
   option yuv '1'
   option quality '100'
   option fps '9'
   option led 'auto'
   option www '/www/webcam'
   option port '8080'

• Save and exit (use :wq command to save and exit).
• Start streaming:

/etc/init.d/mjpg-streamer start

• Navigate to http://192.168.3.1:8080 to see the first stream from your camera!

NOTE: The colors in this test image may not look as expected, as PT does not support MJPEG and MJPEG streamer does not support YUV. Follow the instructions below to use MOTION to solve this, and provide a true-color image from the FLIR sensor.

Advanced Software Setup - Motion

• Stop MJPG-Streamer:

 /etc/init.d/mjpg-streamer stop

• Enable 'packages':

vi /etc/opkg/distfeeds.conf

• Update packages:

opkg update

• Install Motion:

opkg install motion

• Change directories:

cd ../
cd etc/

• Edit motion.conf

vi motion.conf

• Edit the following lines:

      framerate 9
  
      quality 100
  
      stream_quality 100
  
      stream_maxrate 9
  
      stream_localhost off

Start Motion:

motion

Navigate to http://192.168.3.1/8081 to see the camera stream.

You should now also notice still images being captured in your /etc folder whenever the camera detects motion!

(Optional) Add V4L Control to Change Color Palettes

• Enable 'packages' and 'reboot_base':

vi /etc/opkg/distfeeds.conf

• Update opkg

opkg update

• Install V4L-utils:

opkg install v4l-utils

• Use WinSCP to copy pt1.xml to Onion from https://github.com/groupgets/purethermal1-uvc-capture/blob/master/v4l2/uvcdynctrl/pt1.xml
• Import the dynamic controls:

uvcdynctrl -v -d /dev/video0 -i pt1.xml

• Check that the controls were successfully imported:

v4l2-ctl -l

• Change color palettes using:

v4l2-ctl -c lep_cid_vid_lut_select=1
