a cost-effective, robust, integrated multi-trigger security and alert system using off-the-shelf or recycled hardware and sensors and open-source software technologies for messaging, video streaming and recording, machine vision, video analytics, thermal and power monitoring and control. It provides multi-channel feedback (Twitter, Email, SMS, etc).

Trigger Events

  • heat (aircon not working, fire)
  • smoke (smoke detector linked to online alarm system)
  • motion (person entering/leaving building or room)
  • sound (fans, batteries failing, alarm of non-networked motion or thermal sensors)
  • power outage

alpha version of the "big plan" for smoke and heat sensors


  • SMS
  • email
  • video recording
  • log recording
  • alarm (sound, light)
  • Tweet
  • phone dialling


IP camera, POE (Power Over Ethernet), direct-to-NAS recording (AFP, SAMBA, or NFS), inputs for PIR sensors, Infra Red light for night vision, mechanical IR-Cut Filter Switch (basic surveillance functions incorporated into the camera; camera sends stream when preset event occurs; system send SMS/email), NAS (www.nas4free.org - ZSF file system 4 TB RAID Z2)

Smoke and Temp Module


This module monitors room temperature independent of on-board temperature sensors (also monitored) in our servers. It is especially useful in keeping optimal temperature for DILC's data center. Cooling the room too much is a waste of energy. Temperature readings are occasionally verified using 3rd-party thermal instruments.
