Video surveillance storage handles data compression and encoding through a combination of techniques to optimize storage requirements and ensure efficient data handling.
Data Compression:
Compression reduces the size of video files without significantly compromising quality. This is crucial for managing large volumes of surveillance footage. Common compression methods include:
H.264/H.265 (HEVC): These are video compression standards widely used in surveillance systems. H.265, in particular, offers better compression efficiency than H.264, meaning it can reduce file sizes by up to 50% while maintaining the same video quality.
JPEG Compression: Used for still images within video streams, this method reduces the file size by removing unnecessary data.
Data Encoding:
Encoding converts raw video data into a format suitable for storage and playback. It involves converting the video signal into a digital format that can be compressed and stored efficiently.
MPEG Encoding: This standard is widely used for video compression and includes various versions like MPEG-2, MPEG-4, and MPEG-7.
AVC (Advanced Video Coding): Another term for H.264, this encoding standard is widely adopted in surveillance systems for its balance of quality and compression efficiency.
Cloud Storage Solutions:
For handling large volumes of compressed and encoded video data, cloud storage solutions are often utilized. They offer scalability, reliability, and cost-effectiveness.
By leveraging advanced compression and encoding techniques, along with robust cloud storage solutions like Tencent Cloud COS, video surveillance systems can effectively manage and store vast amounts of data while maintaining high-quality video output.
