Surface water is water that enters the dwelling from the surface of the ground because of inundation or insufficient drainage and causes loss to the dwelling. Coverage for surface water intrusion [5] to the dwelling would usually require a separate flood insurance policy.
The technology typically found in motion sensors to trigger an alarm includes infrared, ultrasonic, vibration and contact. Dual technology sensors combine two or more forms of detection in order to reduce false alarms as each method has its advantages and disadvantages. Traditionally motion sensors are an integral part of a home security system.
A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage. A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance across two contacts.
Internet of Things (IoT) security devices are electronic tools connected via Internet to a common network and are used to provide security measures. These devices can be controlled remotely through a mobile application, web-based interface or any proprietary installed software, and they often have capabilities such as remote video monitoring, intrusion detection, automatic alerts, and smart ...
A fence-mounted perimeter intrusion detection system installed on a chain link fence. A perimeter intrusion detection system ( PIDS ) is a device or sensor that detects the presence of an intruder attempting to breach the physical perimeter of a property, building, or other secured area.
Founded in 1994, Future Fibre Technologies product line provides optical fiber intrusion detection systems for perimeters, buried oil and gas pipelines and data communication networks. FFT currently hold a number of patents for its fiber optic sensor and signal processing technologies, and is recognized as a global Tier One supplier in the ...
This relay completes the circuit across a pair of electrical contacts connected to a detection input zone of the burglar alarm control panel. The system is usually designed such that if no motion is being detected, the relay contact is closed—a 'normally closed' (NC) relay.
