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

12. 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.
