ABSTRACT:
Video surveillance system which records compressed video signals on a record medium that have been compressed at a controllably selectable compression ratio. An image is picked-up by a camera and a video signal is produced therefrom. The video signal is compressed at a selectable compression ratio depending on the occurrence of a predetermined condition and the compressed video signal is recorded on a record medium. If the occurrence of a predetermined condition or event (or events) is not detected, the compression ratio is established to be a relatively high compression ratio, whereas upon the detection of the occurrence of the predetermined condition or event, the compression ratio is established to be a relatively low compression ratio. In addition, the compressed video signal may be recorded intermittently or continuously on the record medium depending on whether the predetermined condition is detected.
