Nonetheless, conventional CCTV setups face numerous obstacles, complicating the task of security teams in identifying and addressing potential threats.
The digital images taken must be pre-processed to improve their quality before they are analyzed. Using digital filtering, the noise in the image can be removed and the contrast enhanced. Sometimes in this step the color image is converted to a gray-scale image, called the intensity image. The intensity is used to divide the images into disjointed regions with the purpose of separating the region of interest from the background.
Definition of CCTV Systems:
Closed-circuit television (CCTV) systems refer to a network of cameras and recording equipment used for surveillance purposes. Unlike broadcast television, the signal in a CCTV system is not openly transmitted but is instead monitored, typically for security and surveillance purposes. These systems are prevalent in various settings, capturing and recording footage that can be reviewed or monitored in real-time to enhance security, deter crime, and assist in investigations.
