Main Components of an ELV System

Surveillance Camera Systems (CCTV)

Surveillance camera systems consist of interconnected cameras for monitoring, recording, and transmitting images to one or more display screens. These systems are widely used in various fields such as transportation, manufacturing, and retail.

Key Functions of CCTV Systems:

• Monitor areas to detect and prevent security breaches, theft, or other dangerous situations.
• Record images and videos for analysis, verification, and investigation when necessary.
• Monitor public order areas like shopping centers, hospitals, and schools.
• Instant alerts in case of incidents through sensors and motion detection features.

LAN/WAN Networks

LAN (Local Area Network) and WAN (Wide Area Network) are commonly used in modern buildings to connect and exchange data between devices and systems.

• LAN: A local network used in smaller areas like buildings or offices, offering high-speed data transmission (100 Mbps to 10 Gbps).
• WAN: A wide-area network connecting LANs in different geographical locations, transmitting data over long distances with lower speeds.

Public Address (PA) System

A PA system is used to transmit announcements, emergency information, and broadcasts in public spaces such as buildings, shopping centers, airports, hospitals, schools, and more. It ensures timely and clear communication.

Key Components of PA Systems:

Microphones, amplifiers, speakers, mixers, and signal processors.

Applications of PA Systems:

• Announcing flight times and directions at airports.
• Broadcasting background music, promotions, or events at shopping centers.
• Hotel information and news announcements.

Fire Alarm Systems:

Fire alarm systems detect and alert people to the presence of smoke, fire, or carbon monoxide in case of an emergency.

Key Functions of Fire Alarm Systems:

• Detect smoke, heat, or fire to provide early warnings.
• Activate alarm lights and bells.
• Trigger automatic fire suppression systems such as water sprinklers, CO2 gas, or foam systems.

Applications of Fire Alarm Systems:

• Protect office employees, customers, and assets.
• Safeguard patients and medical staff in hospitals.
• Ensure worker safety in factories and industrial zones.

Access Control Systems

These systems control access to secure areas by managing who can enter and exit premises, providing enhanced security and protection.

Advantages of Access Control Systems:

• Prevent unauthorized access, enhancing security.
• Track and report user entry and exit.
• Easy integration with other systems like alarms and surveillance cameras.

Cable TV/Internal TV Systems (MATV/SMATV)

These systems serve internal entertainment, information, and advertising needs, typically in office buildings, apartments, hotels, hospitals, and complexes.

• MATV (Master Antenna Television): Uses a main antenna to receive TV signals and distributes them throughout the building.
• CATV (Community Antenna Television): Provides additional channels, including paid services, through coaxial or fiber optic cables.

Benefits of Implementing ELV Solutions

The ELV system plays a crucial role in improving the quality of life, work efficiency, and safety in buildings. Implementing ELV solutions offers many benefits, including:

• Enhancing security and protection.
• Optimizing costs.
• Improving management and operation efficiency.
• Enriching user experience.
• Saving energy.
• High integration and automation capabilities.
• Increasing property value.
