The DEPA Platform – Intelligent Video Analytics

Intelligent Motion Detection Filter (Passing-Directional)

The SNC-DF80 and SNC-DF50 cameras offer intelligent video analytics, based on the Sony DEPA platform. This comprises two elements: intelligent built-in camera functions, such as IMD and IOD, and rules/filters that determine which images should be recorded or when an alarm should be triggered.

When the network cameras perform IMD or IOD, ‘tagged’ objects and their associated metadata, including object position data, are sent either to the NSR Series recorder or the IMZ-RS400 Series software. These products then use the metadata, together with filters, to analyze object movement and to perform a predefined action, such as image recording or alarm triggering.

High-quality Images

SuperExwave Technology SNC-DF80

The SNC-DF80 incorporates an advanced 1/3-type CCD with SuperExwave technology that achieves extremely high sensitivity levels. The camera provides a minimum illumination of 0.6 lx in color and 0.06 lx in B/W at F1.3, allowing it to capture clear and detailed images even under low light conditions. The high-quality CCD imager, in combination with the camera’s state-of-the-art DSP technology, produces a high horizontal resolution of 540 TV lines via the analog composite video output, which provides amazingly clear and detailed images.

Wide Dynamic Range With

DynaView Technology SNC-DF50

The SNC-DF50 incorporates DynaView technology, which dramatically improves camera dynamic range by 128 times when compared to conventional cameras. This results in clear image reproduction,

even in extreme high-contrast environments. The<Normal Shutter Speed> camera captures the same image twice – first with a

normal shutter speed, and then with a high shutter speed. The dark areas captured at normal shutter speed and the bright areas captured at high shutter speed are then combined into one image using an advanced DSP LSI. Additionally, as these high-contrast scenes may have different lighting conditions, two white balance circuits are employed – one for normal shutter speed and the other for high shutter speed. This advanced technique reproduces high- contrast images with proper color.
