Recently, ultra-high-definition surveillance cameras introduced 4K resolution to the security industry. However, 4K resolution has yet to achieve wide application, mainly because of the tremendous bandwidth and data storage requirements. Limiting the bitrate of an ultra-HD video feed while retaining a high-quality, 4K-image remains the biggest problem—a problem whose solution will decide the fate of ultra-HD surveillance video. Video transmission balances image quality, transmission capabilities, and data requirements—i.e., how much information and how it is handled. Therefore, image transmission optimisation lies in advancements in video compression technology.
