The Hitachi DI-SC120R, now available from Premier Electronics, features a 1/3-inch CCD sensor with a full resolution of 1,280 x 720 pixels. Hitachi has combined its Digital Signal Processor (DSP) to a high-sensitivity CCD sensor and 30x lens to achieve a minimum subject illumination of 0.5 lx.
The DI-SC120R includes a new feature, defog, that the camera processes in real time. Images are resolved for highly magnified stable images in foggy conditions such as urban surveillance, traffic monitoring and pole mounted applications. The camera measures each pixel for fog thickness and applies contrast to the image to offer a uniform image. The zoom functionality enables 30x optical zoom in high definition and achieves swift subject tracking through Hitachi’s high-speed auto focusing system. High resolution and high power zoom facilitate the accurate capturing of video providing important evidence in many applications, including urban surveillance and number plate capture of distant vehicles.
Electronic image stabilisation compensates for vibration or movement of the camera, automatically minimising image blur. Images in which the luminous intensity varies greatly indoors and outdoors, at the entrance of a building for example, are prone to the occurrence of whiteout or loss of dark detail, reducing visibility. The Hitachi DI-SC120R employs enhanced automatic wide dynamic range correction functionality in order to improve visibility in these conditions. Two methods are used, resulting in double the effectiveness of the previous model (VK-S655N). The first method uses a composite of images taken at two different shutter speeds, while the second employs a contrast offset that corrects the contrast for an image pixel by pixel. This enables improved recognition of the subject even in areas of extremely large differences in illumination.
The camera provides dual protocol (AFP/EAP), wide operating temperature range from -10 to 60°C, 16-bit digital output, frame noise reduction, 3D privacy masking, motion detection, digital image flip, and low power consumption. The camera measures 50 x 60 x 89.5mm and weights 260g.
