Pov

what is it

POV is the (virtual) server managing the webcams. It stores video files of all webcams over the last 2 days.

OS specifications

• debian stretch
• 32b
• virtual machine with 2 cores
• 1GB ram
• 10GB root filesystem
• 100GB storage for camera files

software

• motion https://motion-project.github.io/
  • used for camera 6 and 11 which are down

• constatus https://vanheusden.com/constatus/
  • all other cameras

motion

• motion is installed from the debian repository
• configuration files are under /etc/motion
• main configuration is motion.conf which includes cam*.conf
• as by the design of motion, all its cameras (6 + 11) are monitored from 1 process

constatus

• installed from the github repository https://github.com/flok99/constatus
• installed under /usr/local/constatus
• started (currently, 20170903) from /etc/rc.local
• each camera has its own constatus process - the idea is that if something crashes, that not all cameras will go down
• video archive can be viewed under http://10.42.19.84:port/ where port is 8101 for camera 1, 8102 for camera 2 and so on

The configuration files are JSON files. They consist of 2 or more sections: general, source and then optional sections. Every other section (apart from video loopback) have an array of entries for their data. E.g.

Recording Specifications

• 5 FPS video files
• 2 FPS HTTP web interface
