The OS04D image sensor is designed to provide the ideal balance of performance and cost for mainstream IP and HD analog security cameras.

The OSO4D sensor enables the camera to capture images with higher sensitivity, ultra-low noise, and better overall image quality even in dark conditions.

Omnivision OSO4D is a 2K CMOS (Complementary metal–oxide–semiconductor ) image sensor developed for consumer security and surveillance applications. The camera sensor comes in a 1/3-inch optical format and has an image resolution of 4 megapixels. It features a 2.0-micron high-performance backside illuminated (BSI) pixel, enabling the camera to capture images with higher sensitivity, ultra-low noise, and better overall image quality. The OSO4D image sensor is power efficient and offers an improvement of over 30% in signal-to-noise ratio when compared with its predecessor. The Omnivision OSO4D will enable designers to make security with better video quality and long-lasting battery run time. Moreover, the higher frame rate will enable it to capture high-quality videos and still images of fast-moving objects. Furthermore, the OSO4D sensor will enable security cameras to have clearer images in darker environments. The image sensor is suitable for use in both analog and IP cameras and can be used in cameras used in smart home surveillance, doorbell and baby monitoring devices.

The OSO4D camera comes with a cost-effective 1/3-inch optical format. The 4 MP image sensor offers up to 2K resolution high-definition (HD) video at 30 frames per second (fps) to IP and HD analog security cameras. The OS04D CMOS sensor supports MIPI interfaces for communications. Omnivision claims that the OS04D CMOS image sensor is 40% more power efficient and offers a 30% improvement in signal-to-noise ratio (SNR1) and 40% in sensitivity when compared with its predecessor. The OS04D image sensor’s 2.0-micron (µm) BSI pixel is based on OmniVision PureCel Plus technology and enables higher sensitivity, ultra-low noise and better overall image quality.

“For security camera image sensors, the most critical component is their ability to produce sharp, high-resolution images. Our new OS04D 2K 4MP CMOS image sensor produces extremely clear images and has fast frame rates to capture real-time, fast-moving HD video,” said Cheney Zhang, senior marketing manager, OmniVision. “One of the most important parameters in security and surveillance is low-light image performance – the OS04D is built on our PureCel®Plus pixel architecture to achieve high quantum efficiency and an excellent signal-to-noise ratio, resulting in extremely high sensitivity in low-light conditions. Ultimately, the OS04D image sensor is designed to provide the ideal balance of performance and cost for mainstream IP and HD analog security cameras.”

The OSO4D is manufactured by OmniVision, a semiconductor company which provides solutions for advanced digital imaging, analog, and touch & display technology, etc. The OSO4D sensor will not only bring down the cost and size of the security cameras but will also enhance the image and video quality of surveillance cameras in all lighting conditions.
