Answer: A CCTV machine is formally called a Closed-Circuit Television (CCTV) system. It consists of cameras, monitors, and recording devices used for surveillance in specific locations. Unlike broadcast television, CCTV feeds are private, transmitting signals only to authorized screens. These …
Answer: CCTV systems use a combination of cameras, video transmission technology, storage solutions, and advanced software. Core technologies include IP (Internet Protocol) cameras, analog HD systems, video compression standards like H.264/H.265, cloud storage, AI-powered analytics, and cybersecurity protocols. Modern systems …
Answer: CCTV systems primarily use coaxial cables (RG59/RG6), Ethernet cables (Cat5e/Cat6 with PoE), or Siamese cables combining power and video lines. The choice depends on camera type (analog/IP), distance, power needs, and environmental factors. Coaxial suits analog systems, while Ethernet …
Installing a CCTV system requires specific electrical materials to ensure functionality and reliability. Essential components include cameras, power supplies, cables (like coaxial or Ethernet), connectors (BNC or RJ45), a DVR/NVR, surge protectors, and mounting hardware. Proper wiring, voltage considerations, and …
CCTV cameras consist of a lens, image sensor (CMOS or CCD), housing, infrared LEDs for night vision, processor, and wiring/power supply. The lens focuses light onto the sensor, which converts it …

To set up a CCTV camera system, you need cameras (wired/wireless), a recorder (DVR/NVR), storage (hard drives/cloud), power supplies, cables (Ethernet/coaxial), monitors, and networking tools. Optional additions include IR …
International standards for CCTV cameras ensure interoperability, quality, and security across global markets. Key standards include ISO/IEC 62676 for video surveillance interoperability, IEC 60950-1 for electrical safety, and EN 50132 for alarm systems. These frameworks address video resolution, data encryption, …
What Are ISO Standards for Cameras? ISO standards for cameras define sensitivity to light and manufacturing quality benchmarks. In photography, ISO measures sensor/film responsiveness, while organizational ISO certifications (e.g., ISO 12233) ensure camera performance consistency. These standards guide exposure settings …
The IEC standards for CCTV cameras are defined under IEC 62676, a series focusing on video surveillance systems. These standards ensure interoperability, cybersecurity, and performance reliability. Compliance guarantees devices meet international safety and functionality benchmarks, covering aspects like image …
Blurry CCTV footage often results from low-resolution cameras, dirty lenses, inadequate lighting, or incorrect focus settings. Upgrade to 4K cameras, clean lenses monthly, install IR illuminators for night vision, and adjust focus …
The primary weaknesses of CCTV systems include limited coverage areas, vulnerability to cyberattacks, dependence on power and internet connectivity, high maintenance costs, and privacy concerns. These flaws reduce effectiveness in crime prevention, expose systems to hacking, and create logistical challenges. …
