Closed Circuit Television (CCTV):
Closed Circuit Television (CCTV) is a surveillance system
extensively utilized in electrical engineering. It employs
strategically positioned video cameras to monitor and record
activities in specific areas or premises. CCTV systems consist of
cameras, recording devices, monitors, and networking
infrastructure. By capturing real-time footage, CCTV acts as a
deterrent against unlawful activities, aids in investigations, and
enhances overall security. Its applications span public spaces,
businesses, and residential areas, ensuring effective monitoring
and safety of people and assets.
Fire Detection and Alarm System (FDAS):
In the realm of electrical engineering, a Fire Detection and
Alarm System (FDAS) is of utmost importance as it identifies and
warns occupants about the presence of fire or smoke in a
building. This system incorporates devices like smoke detectors,
heat detectors, fire alarms, and control panels. When fire or
smoke is detected, the FDAS activates alarms such as sirens,
lights, or voice evacuation systems. By promptly detecting fires,
FDAS plays a critical role in safeguarding lives and minimizing
property damage through early detection and swift response.
Background Music Paging System:
A Background Music Paging System is an auxiliary system
commonly encountered in various environments like retail stores,
offices, hotels, and airports. It serves a dual purpose by providing
pleasant background music and facilitating public
announcements throughout the facility. This system comprises
speakers, amplifiers, audio sources, and control interfaces.
Background music creates a welcoming atmosphere, while
paging capabilities enable broadcasting announcements or
emergency notifications to specific zones or the entire premises.
This system enhances communication, creating an engaging and
informative environment for occupants.
