Which type of image sensors are predominantly used in modern IP cameras?

In modern IP cameras, CMOS (Complementary Metal-Oxide-Semiconductor) image sensors are predominantly used due to several advantageous characteristics. CMOS sensors are generally more energy-efficient compared to CCD (Charge-Coupled Device) sensors, which allows for longer battery life in portable devices and less power consumption overall. Additionally, CMOS sensors typically integrate more functionality on-chip, enabling features such as image processing, which can enhance the camera's performance and capabilities.

The manufacturing process for CMOS sensors is often less costly than that of CCD sensors, leading to cost-effective production of cameras. CMOS technology also allows for faster readout speeds, which improves the camera's ability to handle high dynamic range scenes and reduces blurring during motion capture.

While CCD sensors are known for their high image quality and low noise levels, the trend towards CMOS sensors is primarily due to their versatility, lower power consumption, and reduced manufacturing costs, making them more suitable for the majority of modern applications in IP surveillance.
