Digital Doorbell

Designed by Joppe Koers in september 2022

Description

This project is a video doorbell system that shows users who is at the front door and allows them to open it.
This system consists of a touchscreen computer that runs headless

• Debian with a=
• xinit window manager, that runs a
• C++17 application with a frontend in
• ImGui with a
• OpenCV3 backend.
  When the user selects a name to call the C++ application calls a
• docker container that runs a
• asterisk SIP server, and uses asterisk's
• originate command to make the front door camera
• AXIS A8105-E call a the selected client's
• IP video phone model:
• Fanvil_I53W
  This happens over a local network that is not connected to the outside internet The touchscreen computer runs a
• DHCP server that manages the local network's IP addresses, and assigns a
• static IP to itself.
  A user can also call a second SIP camera in the hallway powered by a
• Raspberry Pi 3 that runs a
• linphone SIP client.
  The system also supports
• calling between users See doc/notes.md for more information.

Changing apartment occupant(s) (names)

1. Connect a computer to the PoE switch
2. ssh into the touchscreen computer: ssh root@192.168.2.18
3. Edit the occupants config file: nano /root/video-doorbell/app/occupants.conf See /root/video-doorbell/app/occupants.example.conf for how to configure it
4. Run /root/video-doorbell/production.sh to load the config file, watch the output, it will tell you if you've not formatted the file correctly
5. Validate that the app has started correctly by making a test call

Get a list connected indoor stations and their IPs

1. ssh into the touchscreen computer as described above
2. run asterisk -rx 'sip show peers'

Components

Why these components? Because they had already been bought, so I might as well use them.
