Digital CCTV cameras utilize a DSP chip to digitize the analog video stream produced by the CCD chip. DSP chip helps the improvement of picture quality and can add more functions. Samsung Techwin has been three analogue DSP chips which are developed in house.
WVdelivers key functions to enhance the image quality of CCTV cameras.
A1 added more functions that can be used to help more convenience monitoring.
SVV is the DSP features ultra high resolution of maximum 650TV Lines and other valuable functions.

 |
| The W-V camera delivers high quality 600TV lines images utilizing a unique image processing technology found only in Samsung Techwin’s 5th generation DSP. |
Featuring SSDR (Samsung Super Dynamic Range), the SCB-2000 automatically increases dark photoelectric signals while retaining bright signals; dark spots in images become more visible for accurate monitoring.
|
|
 |
| DIS (Digital Image Stabilization) removes image jitter that is caused by vibrations in the building. This stabilization greatly reduces the amount of hard disk space required to store images on a DVR. |
|
 |
| The W-V utilizes Day & Night control to enhance performance in low lighting conditions. The W-V cameras can deliver outstanding images around the clock in challenging lighting conditions |
Managing noise is the key to achieving great results in low light. The advanced 2D/3D noise filtering system in the W-V allows it to provide good color in much lower lighting levels. Reducing noise in the picture also reduces the amount of storage space required to record the video on a DVR.

|
 |
| Advanced features can be easily optimized with the use of the on-screen display menus that are available in six different languages. These menus can be accessed locally at the camera via pushbuttons or remotely from an optional low cost hand-held controller, or from the monitoring location center via RS-485. |

SV-V/A1 camera technology eliminates false colour artifacts (Moire) by utilising a special optical low pass filter and is able to resolve a horizontal resolution of 600TV lines, by means of 12 Bit A/D serial signal processing coupled with image element enhancement technology. Additionally, the implementation of a 3 line processing algorithm to prevent noise under low illumination applications, directional adaptive filtering and adjustment of aperture gain by luminance level combine to provide a more vivid and clearer image.

 |
| SV-V/A1 camera models featuring WDR functions generate images using Double Scan CCD technology and these cameras provide VPS (Virtual Progressive Scan) operation which can utilise either Interlace or Progressive scanning methods. This VPS is unique to Samsung and ensures the edges of moving objects are clearly defined. Applications for Samsung cameras utilising this technology include highway and ANPR projects. When used with LCD monitors offering progressive scan operation, Samsung VPS produces visibly superior images to non-VPS cameras. The problems of the blurred edges resulting from delays in even/odd field image scanning, are eliminated when VPS technology is used with a network product |
The SSNR/DNR function eliminates noise thus generating a distinct and clear image. SV-V/A1 technology utilises both an adaptive 2D filter reducing noise of moving parts and an adaptive 3D filter reducing noise of fixed parts. These filters are combined with DNIe technology which is applied to Samsung CCTV monitors. The result is that SV-V/A1 camera series support SSNR/Motion Adaptive DNR function that removes noise (Fixed Pattern, Random, etc.) and greatly reduces motion blur.

Under strongly backlit or high contrast scenes, cameras generally produce images which reproduce detail in the brighter area of the scene.(fig1) Consequently, detail is often lost in the darker areas of the scene. Samsung SV-V/A1 cameras provide SSDR/XDR technology to increase the level of visible detail in the dark areas, whilst maintaining image clarity and detail in the brighter portions of the image. (fig2)

The Samsung SV-V/A1 series of cameras, also provide built-in capability for video content analysis. Operational modes include :
. Fixed : Senses objects that appear and remain in a scene for longer than a pre-determined period of time.
. Moved : Detects objects removed from a scene
. Fence : Provides virtual electronic area [Area mode] and directional line [Line mode]
and generates an alarm in the event of a breach of the area or a cross of the directional line.
. Tracking : Tracks an object through a scene and generates an alarm in the event of
abnormal directional changes.
. Counting : Provides the counting numbers of the objects pre-determined direction. (SV-V)

The Samsung SV-V/A1 series cameras offer camera control via the video coaxial cable. This function provides access to the camera settings menu without connecting the any other control lines to the camera. This technology allows for camera set up (with the exception of lens focus) to be performed remotely, thus simplifying the installation process and offering remote adjustment in real time.
|
 |
| The SV-V/A1 DSP technology compensates for backlight problems 128 times more effectively than standard BLC, by applying an optimum fusion ratio when combining the high speed shutter used in bright areas and the low speed shutter used in dark areas. It carries out a precise analysis on the picture to get detailed information from the dark areas without any saturation from the bright areas. |
SV-V/A1 cameras have the capability of digitally compensating for camera shake commonly caused by wind or air handling equipment. Removing even minor vibration in the picture results in significant savings in DVR storage space.

 |
| A"privacy zone" can be set if you desire to block viewing of specific areas in the picture. |
