Description

The project is designed as a end to end solution for a DIY Home Monitoring & Intruder Alert system. Besides offering a live video stream on any device (web responsive client), it also actively monitors for movement with the help of a PIR sensor.

If an Alarm is triggered, you get a SMS notification on your phone and the snapshots taken during the Alarm time span (customizable - default is 1 minute) are uploaded via FTP to your server.

Activation / Deactivation of the Alarm Mode can be done in 2 ways:

  1. from the Web Client user interface
  2. with a Button - for convenience reasons: it is faster than connecting from your phone / pc & toggling the Alert Mode checkbox
    • there is a 10 seconds customizable delay which allows you to move out of the PIR sensor range
    • a Led indicates the Alarm Mode enabled/disabled status

In order to avoid false positives from the PIR motion sensor, extra checks were added - a detection counter & detection interval. The Alarm gets triggered when the sensor detects movement 3 times in 5 seconds (both values configurable in code).

Technology

The project was developed using:

Generic Application.js

It is the basic application object, defined to be reusable in other projects Contains the basic server code, generic config file read/write operations, generic Init & Execute & Exit methods implementations

Web Client - responsive

The client application was designed to be accessible on all platforms (pc / tablet / mobile).

Video streaming quality settings

By default the 480p at 25fps is enabled (initial settings are loaded from the config.ini file)

My webcam is a low-end 5+ years old 2mp device, but for those of you with better webcams I also added 720p & 1080p

Video resolutions & fps can be configured from the /static/js/script.js file 

//only check quality settings
if(ui.quality480p.prop('checked')) {
    appConfig.monitoring.quality = "640x480";
    appConfig.monitoring.fps = 25;
}
if(ui.quality720p.prop('checked')) { 
    appConfig.monitoring.quality = "1280x720";          
    appConfig.monitoring.fps = 25;
}
if(ui.quality1080p.prop('checked')) { 
    appConfig.monitoring.quality = "1920x1080";         
    appConfig.monitoring.fps = 25;
}

//send to server new config settings
socket.emit('update config quality', appConfig);
