Infrared Beam Sensors/Beam Detectors

  Beam Detectors For the purpose of detecting motion, infrared sensors use infrared wavelengths. Although there are many uses for IR sensors, they are most frequently utilised in security systems installed in homes and businesses. Active infrared (AIR) sensors and Passive infrared (PIR) sensors, often known as infrared detectors, are the two types of infrared sensors. Our comprehensive reference to AIR sensors is solely for infrared beam sensors, also known as photobeam sensors, which use Active Infrared (AIR) to detect motion. Active infrared (AIR) sensors are the kind of sensors that use a transmitter to send out infrared radiation that are then picked up by a receiver. Any change in the waves' path shows the presence of an object. Working of Beam Detectors : The transmitter emits an infrared beam that travels in a straight line thanks to an infrared LED inside of it. The IR waves travel in a straight line from the transmitter to the IR receiver, which is located directly across ...

Anti Theft Alarm

 An electronic security system called an Anti Theft Alarm is installed at specific locations to deter theft or to catch trespassers in the act. It is an entire system with various security sensors and equipment performing their specific functions at various locations, including entrances, perimeters, interiors, exteriors of the premises. Anti Theft Alarm Working Principle : Circuit Break - Devices are installed on doors and windows as part of a complete security system to detect any forced entry. These gadgets are made up of electric circuits with switches that control the flow of electricity in the circuit. In a typical situation, the circuit's electric current keeps flowing and the system stays in the alert mode. The electric circuit is broken and the flow of current is interrupted when someone enters the area violently. When the electric current stops flowing, the gadget enters panic mode and sends a signal to the control panel informing it that there is suspicious activit...

Intrusion Detection System

An   intrusion detection system   is an electronic security solution that notifies the property owner or the security guards on duty when an unauthorised entry into a home, office, factory, warehouse, etc. is detected. The Intrusion Detection System is made up of numerous sensors and other electronic parts that work together to offer unmatched security around-the-clock. The entire system serves as a barrier against intruders and gives early alerts in the event of an incursion attempt. Components : Control Panel – Control Panel is the most important component of an Intrusion Detection System. It is the main panel with which all other components are connected through wires or without wires. Control Panel acts as the brain of the whole Security system continuously receiving signals from all the components. Motion Detectors – Motion Detectors are the essential part of an Intrusion Detection System that work on the principle of detecting objects with the help of waves they emit. O...
