The Different Types of Fire Sensors

fcam3For reliable fire detection, there are various types of fires sensors available.

These fire sensors can greatly differ in how they work in where they can be installed.

Here we want to look at the most common types of fires sensors and explain some of the differences.

Smoke detectors

Smoke detectors are the most common types of fires sensors. They are widely used in commercial and residential buildings where they can provide reliable fire detection. How do smoke detectors work? Smoke detectors make use of a light sensor. In case of smoke, where the air will be containing smoke particles, the increased reflectivity of the smoke in the air will trigger the sensor. These systems are affordable, and they are rather simple to install and maintain. The big downside of these systems is that they can only work reliably in the indoors, in confined spaces.

Fire cameras

Fire cameras are the latest innovation in fire detection technology. They work very differently as compared to smoke detectors. Essentially, fire cameras are CCTV video cameras with integrated digital image analysing software. This way, a fire camera can detect a fire by analysing a video feed, rather than needing to rely on smoke or heat. This makes these types of fires sensors a lot more versatile in how they can be used.

One of the biggest advantages of a digital fire sensor including modern digital fire cameras is that they can operate remotely. They can monitor locations for fires from several hundreds of metres away. This makes them also suitable for the outdoors and other such locations where smoke detectors cannot work reliably.

While in the past, certain locations for example forests required visual observation by people to detect fires, these new systems now can work faster and even more reliable.

This new generation of fire sensors is greatly increasing the fire safety in places where fire detection had been a major challenge only several years ago.
