When do I need H.265/HEVC?
H.265 / HEVC is a new compression standard that has emerged as the need for better video compression has increased as the resolution of surveillance cameras becomes higher and higher. To limit bandwidth and storage requirements, this new standard is very efficient. It provides the same or better image quality with half the storage requirements. This is why HEVC is recommended for high resolution cameras, such as AVTECH's 5-megapixel cameras.
How does compression work?
Unlike H.264, which was and is the most common compression standard, H.265 can compress twice as much without affecting video quality. Put simply, H.265/HEVC uses more advanced algorithms than before. Technically, the compression is achieved through a smarter system of comparing successive image sequences and saving the parts of the image that are similar. By creating a variable size of the areas of the image that are the same, HEVC becomes significantly more efficient than H.264. In addition to this part, there is also motion-compensated prediction of where pixels will be in the next image sequence plus some other smart improvements.
What devices support H.265/HEVC?
AVTECH's latest IP cameras and the newly developed video storage device AVH8516 support the connection of cameras with the H.265/HEVC compression standard. These devices are also packed with other smart features, such as scenario control, WDR and intelligent video analytics.
