Weak current systems, unlike strong current (power) systems, operate at low voltage and current. They are crucial for security, safety, and operational efficiency in various settings, from residential homes to large commercial complexes. These systems typically include:
Closed-Circuit Television (CCTV): [Insert image: Example of a CCTV camera with its components labelled - lens, sensor, housing, etc.] CCTV systems use cameras to record and transmit video signals, providing visual surveillance and security.
Access Control Systems: [Insert image: Example of an access control panel with card reader, door strike, and keypad.] These systems manage entry and exit to restricted areas, using technologies like card readers, keypads, and biometric scanners.
Fire Alarm Systems: [Insert image: Diagram of a fire alarm system showing smoke detectors, heat detectors, control panel, and notification appliances.] These vital systems detect and alert occupants in case of fire, enabling timely evacuation and emergency response.
Intruder Alarm Systems: [Insert image: Example of various intrusion sensors – motion detectors, door/window sensors, etc.] These systems detect unauthorized entry and trigger alarms, deterring intruders and summoning help.
Public Address (PA) Systems: [Insert image: Simple diagram of a PA system showing microphones, amplifiers, and speakers.] Used for announcements, warnings, and background music in various settings.
