· Image enhancement- surveillance video images often are of poor quality. This is usually caused by light conditions. The images and videos can be enhanced to create a clearer image. · Surveillance Systems · Sequential Switchers- the cameras are recorded on the videotape in a sequential method. This means is there are four cameras; several frames on the tape will cover the same video camera. · Multiplexers- the cameras are recorded on the tape often in fields. This means that each field will cover on camera. The system in often combined with an alarm system in such a way that more images are recorded if there is movement at the place the camera is recording. · Quad Compressors- This is the oldest system, in which the image is divided into four parts and each part will cover another camera.  · Noise Removal · Many types of noise exist in a surveillance system <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· <span style="font-family: 'Times New Roman','serif';">Dangers in Noise Removal are that the tape and quality of the video may be damaged if it is played too much <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· <span style="font-family: 'Times New Roman','serif';">Averaging over multiple frames and super resolution are used in forensic science to reduce noises <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· <span style="font-family: 'Times New Roman','serif';">Image Restoration <span style="font-family: Symbol; mso-bidi-font-family: Symbol; mso-fareast-font-family: Symbol; msobidifontfamily: Symbol; msofareastfontfamily: Symbol; msolist: Ignore;">· <span style="font-family: 'Times New Roman','serif';">In the past, research has been published on image restoration of a video sequence by calculating the movement or the blur of a lens system.
