Thermal Imaging Cameras for Security & Fire Detection
Introduction
A thermographic camera (also called an infrared camera or thermal imaging camera) is a device that forms an image using infrared radiation, similar to a common camera that forms an image using visible light. Instead of the 400–700 nanometre range of the visible light camera, infrared cameras operate in wavelengths as long as 14,000 nm (14 µm). These cameras are widely used in the early detection of fires and in searching for people for both security and safety purposes.
Services Offered
All systems are installed to relevant local, British and European standards with the safety of our clients being the highest priority.
Latest technology
Uncooled thermal cameras use a sensor operating at ambient temperature, or a sensor stabilized at a temperature close to ambient using small temperature control elements. Modern uncooled detectors all use sensors that work by the change of resistance, voltage or current when heated by infrared radiation. These changes are then measured and compared to the values at the operating temperature of the sensor.
Uncooled infrared sensors can be stabilized to an operating temperature to reduce image noise, but they are not cooled to low temperatures and do not require bulky, expensive cryogenic coolers. This makes infrared cameras smaller and less costly.
Typical sensitivity to heat will be +/- 5 degrees C on entry level models and +/- 2 degrees C for higher end models and operating ranges from -20 degrees C to +2000 degrees C.
Fire Alarm integration
Many types of material will internally generate heat without exposure to an external force. The temperature of the material can rapidly increase to the point where they combust. The resulting fire and heat can cause other material to ignite resulting in an unpredicted and violent fire which could ultimately destroy and entire site or building.
Although many buildings are equipped with fire alarms and fire fighting systems, these systems only give warning once the fire has already started. Thermal imaging can help to detect hot spots before a fire occurs so that the necessary measure can be taken.
Sophisticated analytic software is used in areas where heat generating vehicles are in operation (such as forklifts, grabs, bulldozers etc) and the heat source from these "moving" targets is analysed and ignored as the system will recognise the signature for what it is.
Items such as conveyor belts would be monitored by a different element of the software and "moving heat" targets would be identified and actioned.
