JPEG stands for Joint Photographic Experts Group. It refers to a common image format that compresses photos to reduce file size while keeping the quality acceptable.
Surveillance systems often use JPEG to save or send still images from security cameras. For example, when motion is detected, the system may capture a snapshot in JPEG format for quick review or remote alerts.
This format helps balance image quality with storage efficiency. Even though JPEG uses lossy compression, it remains useful for saving bandwidth and conserving disk space.
Unlike video formats, JPEG files are lightweight and easy to transfer. As a result, many systems rely on JPEG for snapshots, email notifications, or cloud uploads.
