Video Compression Techniques in CCTV Cameras

Home / Blog / Video Compression Techniques in CCTV Cameras

Video compression in CCTV cameras is essential for managing large volumes of footage while maintaining high quality. The commonly and primarily used technique is lossy compression methods, which reduce file sizes by eliminating less noticeable data.

H.264 (AVC)

H.264, also known as Advanced Video Coding (AVC), is one of the most widely used video compression standards in CCTV systems. It offers a good balance between compression efficiency and video quality, making it suitable for both live streaming and storage.

 H.265 (HEVC)

H.265, also known as High Efficiency Video Coding (HEVC), is the successor to H.264. It provides approximately double the compression efficiency of H.264, meaning it can deliver the same video quality at half the bit rate. This makes H.265 particularly advantageous for high-definition and 4K surveillance footage.

 Enhanced Video Compression

Enhanced video compression plays a critical role in modern surveillance systems, enabling efficient storage and transmission of high-quality video footage. Among the various technologies. Enhanced Video Compression is an optimized version of H.264 and H.265, specifically designed for surveillance applications. We clarify that H.264+/H.265+ and enhanced video compression are synonymous terms. We have intentionally unified these terms to prevent any confusion with terminologies used by other companies. This ensures clarity and precision in understanding the advanced video compression technology employed in our products.

Advantages of Enhanced Video Compression in CCTV

Reduced Storage Requirements: Enhanced compression significantly reduces the size of video files, allowing more footage to be stored without needing additional storage devices.

Lower Bandwidth Usage: Smaller file sizes mean less bandwidth is required for transmitting video feeds, which is crucial for remote monitoring.

Improved Image Quality: Advanced algorithms ensure that video quality remains high even at lower bit rates.

Cost Savings: Reduced storage and bandwidth requirements translate to lower costs for infrastructure and maintenance.

 Uses of Enhanced Video Compression in CCTV

Surveillance Monitoring: Enhanced compression allows for continuous monitoring without frequent storage upgrades.

Remote Access: Efficient compression enables smooth streaming of live feeds over the internet, facilitating remote surveillance.

Archiving: Long-term storage of surveillance footage becomes feasible without excessive storage space.

Real-time Analysis: Compression algorithms facilitate real-time video analysis and motion detection, essential for proactive security measures.


Enhanced video compression plays a pivotal role in contemporary surveillance systems by significantly enhancing the efficiency of storing and transmitting high-quality video footage. In essence, enhanced video compression and H.264+/H.265+ are synonymous, both leveraging the same technological principles to achieve superior compression efficiency.

As technology continues to evolve, enhanced video compression remains indispensable in enhancing the overall effectiveness and reliability of surveillance operations across various industries.
