- 2. Edge Computing • Edge computing is a technology that allows resources to be processed or executed close to the edge of the internet. • Edge computing is the act of moving power, decentralizing the network, and other functions away from a single hub into the device around the edge. • It ensures that data processing and storage are carried out on network edges closer to the Internet of Things users, rather than on centralized points and cloud servers. When data, applications, and computing power are operated away from integrated points to locations closer to the user, distribution of storage and power leads to better performance.
- 8. Smart Security Elements • Industrial smart security systems combine sophisticated technology to protect residents and critical assets. These systems include: • Connected devices • Sensors • Video technology (e.g., internet protocol (IP) cameras) • Artificial intelligence • Advanced software and analytics • High-uptime networks

EO (Electro-Optic) sensors • EO sensors sense the electric field by measuring the polarization of laser beams transmitted by EO crystals (optical crystals with the Pockels effect as a primary EO effect) whose birefringence changes in response to the applied electric field. • Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. These sensors are able to detect electromagnetic radiation from the infrared up to the ultraviolet wavelengths. • **Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.
- 13. Radar Sensor • the speed of an object along with its direction by detecting the change in frequency wave which is known as Doppler Effect. • A radar sensor includes an antenna that emits a high-frequency (62 GHz) transmitted signal. This transmitted signal also includes a modulated signal with a lower frequency (10 MHz). This sensor gets the signal once it is returned back from an object. So this sensor evaluates the phase shift between the two frequencies. Here, the difference in transmitting time & receiving time will determine the distance between the sensor & an object.
- 14. DIVER DETECTION SONAR • Dealing with underwater threats such as divers or light underwater vehicles requires incorporating highly specialized sensors into the surveillance system that can detect divers or other underwater intrusions, like underwater vehicles. • Once the system is deployed, it continuously emits acoustic pulses, the echoes being received and analysed automatically. • By detecting a threat and tracking it, an alert is automatically generated, indicating the position, speed, trajectory and type of contact, enabling the emission of a deterrent message to the diver in the water and the deployment of a patrol to the area. In addition, the system incorporates powerful processing algorithms to minimize false alarms.
- 15. Fence Sensors • Fence-mounted sensors detect and locate intruders at the fence line, before they get inside a property. • Cable, fiber optic, or accelerometer-based, the systems work with most fence types, including chain- link, welded mesh, expanded metal mesh, and palisade. The sensors enhance the security value of fences by detecting attempts to cut, climb or otherwise break through the fence. Fence sensors may also be used on non-standard fence types and interior and exterior walls.
