The DEPA Platform – 
Intelligent Video Analytics

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. This method of distributed processing

minimizes server workload, network bandwidth, and

storage requirements.

High-quality Images

SuperExwave Technology

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

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

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.
