Sony has developed system ICs for analog security cameras, the Effio-V (CXD4141GG) and Effio-A (CXD4151GG) with drastically improved functions and performance as the third generation of the EffioTM series. The Effio-V and Effio-A can be combined with 960H CCD image sensors to realize the highest horizontal resolution over 700 TV lines in the Effio series. Also the ICs improved overall functions such as noise reduction (3D-NR), exposure optimization of infrared LED, wide dynamic range (WDR), or defog. And visibilities in different conditions with low light, infrared light, or high (low) contrast were greatly improved.
Furthermore, the ICs have the industry's first*1 automatic scene detection function and scene selection function, and they require only one action to secure the ideal picture quality in various installation environments of security cameras.

The Effio-V and Effio-A revised high resolution signal processing and realized horizontal resolution over 700 TV lines, exceeding 650 TV lines of the existing Effio series. (Photograph 1)
Better 3D-NR function ensures less blurry moving subjects, vivid and high SN ratio images even under low light environments. (Photograph 2)
Also, to effectively prevent situations when excessive reflection with infrared light hides the details of subjects (saturation phenomenon) or when around the outer edges of image view angle get darker (shading), the conventional exposure optimization of infrared LED was expanded to enable luminous intensity control of infrared light and shading suppression.
Therefore, these functions greatly improved the visibility in low light environments.
The existing products required proper operation on each function to adjust images depending on where security cameras are installed.
Some installations needed long adjusting time or several cameras with different picture quality characteristics.
The Effio-V and Effio-A have the automatic scene detection function and require only one action to automatically detect 40 patterns of imaging scenes for the ideal images such as dynamic range, color temperature, flicker, or backlight.
The scene selection function presets common scenes for security cameras at indoor, outdoor, traffic surveillance, or backlight, and automatically adjusts based on the setting conditions for the ideal picture quality.
These automatic adjustment functions of picture quality simplify the installation.

This time integrated Digital PLL reduced the number of necessary parts for external synchronization.
Also to optimize the improved ISP algorithm, the control has been renewed from the existing Effio series and functions including automatic scene detection were added to simplify the installation.
The Effio-V and Effio-A are definitely products worth considering.
