Camera Sensors and Image Processing
Cellular security cameras are equipped with advanced camera sensors and image processing capabilities that allow them to capture high-quality images and videos. These sensors are responsible for converting light into electrical signals, which are then processed to produce the final image.
The camera sensors in cellular security cameras are typically CMOS (Complementary Metal-Oxide-Semiconductor) sensors. CMOS sensors are known for their low power consumption, high-speed data transfer, and excellent image quality. They consist of an array of millions of tiny photosensitive elements called pixels.
Each pixel in the sensor is responsible for capturing a specific portion of the scene. When light hits a pixel, it generates an electrical signal proportional to the intensity of the light. These electrical signals are then converted into digital data by an analog-to-digital converter (ADC) integrated into the camera sensor.
The digital data from the camera sensors is processed by the onboard image processing unit. This unit applies various algorithms and techniques to enhance the captured images and videos. It adjusts parameters such as brightness, contrast, sharpness, and color balance to improve the overall image quality.
