Which type of camera uses a digital signal to display images without streaks?

The correct choice is the camera that utilizes a digital signal to provide clearer image quality, free from streaks. A CMOS camera is particularly designed with a complementary metal-oxide-semiconductor sensor, which enables it to process images in a way that effectively reduces motion blur and streaking. This is due to its ability to capture and convert light into electronic signals quickly, enhancing image clarity and stability.

In contrast, analog cameras transmit continuous signals, which can sometimes lead to streaks especially under low light conditions or with fast-moving subjects. Wireless cameras may refer to a variety of technologies, including both analog and digital signals, and do not inherently address the streaking issue. IP cameras, while also digital and capable of providing high-resolution images, are distinct in their networking capabilities and handling of data rather than specifically emphasizing the reduction of streaking as a key feature.

Thus, the CMOS camera's design and function make it the best fit for the prompt regarding clear imagery without streaks, highlighting its advanced technology suited for modern CCTV systems.
