Security sensors and systems are used for access control, burglary, smoke or heat detection, and video monitoring or surveillance.
Fire alarm control panels (FACPs) transmit signals between fire detection devices and alarms, suppression systems, and monitoring centers. This device reduces the potential for fatalities and property loss from structure fires.
Fire sprinkler heads deliver a high-pressure flow of water or dry chemicals to a fire. They are usually are heat-activated and part of a larger fire prevention and safety system.
Flame detectors monitor and analyze incoming radiation at selected wavelengths.
Heat detectors are fire detection devices that sense heat produced by combustion. Heat detectors can trigger an alarm when they detect rapid temperature rise or reach a preset temperature.
Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects.
Smoke detectors are designed to sense the products of combustion. Common types include ionization chambers and photoelectric devices.
Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component.
Video cameras record live-action scenes that are available for viewing via a stored or transmitted video feed. This allows the user to create a permanent and detailed chronicle of events. Video cameras record dozens of pictures (or frames) a second that when viewed in succession, clearly distinguish the translation of an object or person over time.
