What is the main benefit of using the lossy compression method?

The main benefit of using the lossy compression method is the reduced file size. Lossy compression works by removing some data from the original file, which significantly decreases the amount of space the file occupies. This reduction in file size is particularly important in applications like CCTV systems, where large amounts of video data need to be stored or transmitted efficiently. By minimizing the file size, storage requirements are lessened, allowing for more footage to be saved over a longer period or enabling quicker uploads and downloads. Additionally, smaller file sizes can facilitate faster streaming of video feeds, making it easier to manage bandwidth when transmitting video over networks.

While other options like improved image quality, faster processing time, and higher resolution might be desirable, they do not directly pertain to the primary advantage of lossy compression, which is primarily recognized for its effectiveness in reducing file sizes.
