The Panasonic WV-SF539 Super Dynamic Full HD Dome Network Camera with IR LED and advanced features like the Full duplex bi-directional audio and SDXC/SDHC/SD memory card slot offers high-quality 24-hour video surveillance in both day and night time lighting conditions. 

High sensitivity for day/night surveillance with IR function, this network camera captures clear images at F/1.3 even in locations with a minimum illumination of 0.06 lux (B&W). The Adaptive Black Stretch technology increases visibility of subjects in dark areas of a video scene without compromising the image quality of brighter areas. The face super dynamic range technology offers blur-free images of the human face. Furthermore, with the progressive scan technology, you can be sure to obtain blur-free images even when the object is in motion. In addition, the UniPhier LSI chip enables this network camera to simultaneously stream real-time imagery in Full HD resolution of 1920 x 1080 at 30 fps. The electronic sensitivity enhancement function Auto (up to 16x) increases the quantity of light stored on the sensor, making the image brighter. In addition, the Auto Back Focus adjusts the position of the MOS sensor to offer stable focus in both color and B&W modes. 

The 2 area VIQS technology is particularly useful in installations where specific areas in a scene are of high interest while the rest of the scene does not need to be captured at the same level of detail.
