What is a common video format used in CCTV systems?

• A. JPEG
• B. MPEG-4
• C. H.264
• D. AVI

Answer: (C)

MPEG-4 is a widely used video compression format in various applications, including CCTV systems. It offers efficient compression, which allows for high-quality video streaming with reduced file sizes, making it ideal for bandwidth-constrained situations common in surveillance scenarios. H.264, also known as AVC (Advanced Video Coding), is recognized for even more efficient compression, enabling the storage and transmission of high-definition videos over limited bandwidth. This makes H.264 a popular choice in modern CCTV systems, especially when ensuring that the captured footage remains clear without taking up extensive storage space. Commonly used video formats like JPEG, while great for still images, do not suit the continuous video stream required in surveillance. AVI, while it can support video files, is less efficient in compression compared to H.264 and thus not as prevalent in contemporary CCTV applications.
