Camara de Seguridad Personalizada con Raspberry PI zero

En esta entrega exploraremos cómo construir una cámara de seguridad personalizada (que se comporte como yo quiero) usando un Raspberry PI zero (puede ser un Raspberry PI 3 también) y el paquete de código abierto motion.
Además haremos que luzca como una cámara profesional usando alguna de las opciones de cámara de Seguridad falsa que hay en el mercado.

Pasos Resumidos

  1. Configurar el Sistema Operativo  ( instructions )
  2. Instalar y Configurar VNC ( instructions )
  3. Instalar y Configurar Motion ( instructions )
    Recordemos que para que motion se active durante el inicio debemos modificar el archivo /etc/rc.local para agregar una llamada motion /home/pi/.motion/motion.config (o la ruta correcta al archivo de configuración de motion.config que se desea utilizar)
    (!) Nótese que motion se puede configurar para que tome fotos durante un evento de movimiento a razón de n fotos por segundo; a su vez se puede configurar para que genere archivos AVI para cada evento de movimiento y que genere un time-lapse AVI también para cada minuto del día.
  4. Archivo motion.conf de referencia
    # Rename this distribution example file to motion.conf

    #     new file with the name indicated for timelapse.
    # Supported formats are:
    # mpeg4 or msmpeg4 - gives you files with extension .avi
    # msmpeg4 is recommended for use with Windows Media Player because
    # it requires no installation of codec on the Windows client.
    # swf - gives you a flash film with extension .swf
    # flv - gives you a flash video with extension .flv

    # mov - QuickTime
