Sensors and Controls @ DILC
Description
a cost-effective, robust, integrated multiple-trigger security and alert system using off-the-shelf hardware and sensors and open-source software technologies for messaging, video streaming and recording, machine vision, video analytics, thermal and power monitoring and control.
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

Output
- SMS
- video recording
- log recording
- alarm (sound, light)
- phone dialling
Specs
IP camera, POE (Power Over Ethernet), direct-to-NAS recording (FTP, 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)
