1. A surveillance system, comprising:
- a video recorder used to record a scene and generate an original video signal, wherein the scene includes an area in need of coverage; and
a video processing module, which receives the original video signal and performs an interference process on a part of the image displaying the area in need of coverage in the original video signal to generate a post-processing video signal for displaying on a display, wherein the interference process prevents the part of the image displaying the area in need of coverage in the post-processing video signal from being identified.
