Camera Based Fire Detection

What Is It?

• Fire Detection System that uses standard CCTV cameras (monochrome, colour or infrared) as sensors.

• Connected to a server that analyses the motion patterns it “sees”.

• Should the motion be recognised as smoke and/or flames, the system will automatically alarm.

• In conjunction with a DVR pre & post alarm can be clearly seen as video, relay contacts operate to link up with Fire Alarm System.
