Anomaly detection is the process of identifying data points, entities or events that fall outside the normal range. An anomaly is anything that deviates from what is standard or expected. Humans and animals do this habitually when they spot a ripe fruit in a tree or a rustle in the grass ...
When polled by the control panel the detector returns a value based on the combined responses from both the optical and heat sensors. They are designed to be sensitive to a wide range of fires. 5. Manual Call Points A Manual Call Point or Break Glass Call Point is a device which enables...

Infrared thermometers typically use lenses to focus infrared light from an object onto a detector called a thermopile. Thermopiles absorb infrared radiation and convert it into heat. The more infrared energy, the hotter the thermopile will get. This heat is converted into electricity. The electrical...
Carbon monoxide sends up to 50,000 people to the emergency room every year. Learn more about how a CO detector can keep your family safe.
Explosives are devices intended to change to an environment in the process of construction, for example, or cause damage and loss of life through a sudden expansion of gases with violence, heat, and noise due to a reaction that may be chemical or nuclear. Explosives are divided into high ...
The light from an object in the field of view passes through the lens and forms an image on the detector at right. Some of the light is then reflected by the detector back into the lens. One of the lens surfaces then reflects the light back to the detector at a different location. ...
Here's a step-by-step look at the process: The thermal camera, equipped with an infrared detector, captures the infrared radiation emitted from all objects in its field of view. The captured radiation data is then processed by the camera's built-in software. An optical system focused ...
