5.1 megapixel imaging sensor for high-end security cameras
The AR0521 is a small optical format 1/2.5-in. (7.13 mm), 5 megapixel (MP) digital image sensor with an active pixel array of 2592 (H) x 1944 (V). It captures images in either linear or high dynamic range (HDR) modes with rolling-shutter readout, and includes sophisticated camera functions such as binning, windowing, and both video and single frame modes.
The imaging solution offers 8, 10, or 12-bit outputs and video performance of 5MP, 60 frames per second (fps) with a 1440p mode for 16:9 video. The superior low-light performance – often an important requirement in security camera applications – is largely due to the larger 2.2 μm BSI pixel that offers higher linear full well and lower noise than a smaller pixel.
Incorporating both an electronic rolling shutter and global reset release, the AR0521 also offers advanced line synchronisation controls for multi-camera (stereo) support. The ability of the AR0521 to produce clear and sharp images is enhanced by digital processing functions, including integrated colour and lens shading correction, digital gain and dynamic defect correction. Primarily aimed at remote video surveillance applications, its operating temperature range of -30°C to +85°C ambient allows the device to be used successfully outdoors in harsh environments.
With programmable optical format (4:3, 16:9 & 1:1) the AR0521 is suitable for multiple use cases in mid- to high-end security applications, including panoramic security cameras, birdseye security cameras, long range security cameras and speed dome security cameras. It occupies a mPLCC (12 x 12 mm) package.
