Secured Perimeter with Electromagnetic Detection and Tracking with Drone Embedded and Static Cameras

Abstract

Perimeter detection systems detect intruders penetrating protected areas, but modern solutions require the combination of smart detectors, information networks and controlling software to reduce false alarms and extend detection range. The current solutions available to secure a perimeter (infrared and motion sensors, fiber optics, cameras, radar, among others) have several problems, such as sensitivity to weather conditions or the high failure alarm rate that forces the need for human supervision. The system exposed in this paper overcomes these problems by combining a perimeter security system based on CEMF (control of electromagnetic fields) sensing technology, a set of video cameras that remain powered off except when an event has been detected. An autonomous drone is also informed where the event has been initially detected. Then, it flies through computer vision to follow the intruder for as long as they remain within the perimeter. This paper covers a detailed view of how all three components cooperate in harmony to protect a perimeter effectively, without having to worry about false alarms, blinding due to weather conditions, clearance areas, or privacy issues. The system also provides extra information of where the intruder is or has been, at all times, no matter whether they have become mixed up with more people or not during the attack.

Development of a Contact Glass-Break Detector for the Highest Security Level

“…The most important technical security component is the intruder alarm system (IAS), which can detect the intruder, trigger the alarm, and call for the armed forces to pacify the intruder [ 7 ]. The central part of the IAS is the control and indicating equipment, which periodically evaluates the current state of the connected devices, such as detectors [ 8 , 9 ]. The detectors can be divided into several categories according to their specific usage.…”

Controlled Electromagnetic Field Based Safety System for Handheld Circular Saw

“…As a result, proximity sensors are a critical element in a wide range of systems [1][2][3][4]. The most commonly used technologies to provide proximity detection are optical, ultrasonic, inductive, and capacitive, and are usually based on the measurement of a change in either an electrostatic field, or an electromagnetic field [5][6][7][8][9][10]. For inductive sensing, the detection is limited to conductive and/or ferromagnetic objects, and the maximum sensing range is typically similar to the coil's diameter.…”
