The automatic identification system (AIS) is an automatic tracking system that uses transponders on ships and is used by vessel traffic services (VTS). AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.

Using the Hikam S5 with the Synology surveillance station was leading to many false positives. These false positives occur when the the camera was switching between day and nights visions.
As there is any software solution to deactivate the night vision mod on the Hikam S5, we’ll do a simple hardware modification.
First step, remove the back cover (4 screws) :

Download the last version on : https://www.arduino.cc/en/Main/Software
Uncompress the archive :
tar -xvf arduino-1.8.1-linux64.tar.xz
Move the new created folder in the optional add-on software packages folder :
sudo mv arduino-1.8.1 /opt/
Make the install script executable :
sudo chmod +x /opt/arduino-1.8.1/install.sh
Install it :
You should have this output :
Adding desktop shortcut, menu item and file associations for Arduino IDE... done!
I used to use a Raspberry Pi as a data logger for many sensors, here is how I create a nice front-end for data visualization.
– Store data : SQLite
– Serve content : Python with Flask
– Plot data : Hightcharts / Highstock

Since November 2016, SSH server on Raspbian is disabled by default. On the first boot, you’ll find a closed door :
Permission denied, please try again.
