Sony introduces new SSC-E470 series camera in order to further strengthen Sony's analogsecurity camera line-up. This new SSC-E470 series is included in the category calledCS-Mount Color High Resolution type with Day/Night function which is expected to show CAGRof sixteen percent between year 2002 and 2006 in terms of world wide quantity base. Themarket share of CS-Mount Color High Resolution type with Day/Night function categoryagainst total CS-Mount Color High Resolution type analogue security cameras is expected tooccupy ten percent in terms of quantity base in year 2002. Sony currently has one SSCseries (SSC-DC590 Series) within the CS-Mount Color High Resolution type with Day/Nightfunction category. Since SSC-DC590 series is equipped with Wide-Dynamic Range function, itis targeted for customer segments such as financial industries which are different fromtargeted segments of SSC-E470 series.
A Wide Auto Tracing White Range - ATW Pro & ATW
ATW is a feature that automatically adjusts the camera white balance to adapt to changesin lighting conditions. SSC-E470 Series provides an extremely wide ATW range of 2,000 K to10,000 K, allowing adjustment-free operation under a variety of light conditions. Userscan choose from two modes: ATW Pro and ATW. ATW Pro mode is ideal when the lightingcondition changes frequently and is particularly suited to applications where the operatorneeds to see objects as they appear to the eye. This ensures that the precise color imageis always obtained.
Back Light Compensation
Unwanted backlighting can often cause the subject matter of the image to be cast intoshadows. The BLC function incorporated in these cameras automatically compensates for suchconditions and allows the subject to be more visible. The BLC mode is selectable betweenOFF and ON.
CCD IRIS
SSC-E470 Series have CCD-IRIS function to automatically adjust the shutter speed dependingon the amount of incident light. As the image brightness increases, the camera adjusts theexposure by automatically reducing the CCD photo sensor's exposure time (chargeaccumulation time). The CCD-IRIS enables to continuously control the exposure byelectronically adjusting the shutter speed in the range from 1/60(NTSC) / 1/50(PAL) secondto 1/100,000 second. Manual iris lens with CCD-IRIS function can be used instead of morecostly automatic iris lens.
Turbo AGC
The SSC-E470 Series cameras are equipped with an advanced Turbo AGC function. This allowsthe user to boost camera gain up to 24 dB, enabling viewers of the image to distinguishthe subject more easily - even if it is shot in low light. The AGC mode is selectablebetween OFF and TURBO.
Day/Night function
SSC-E470 Series features a Day/Night capability, which provides optimizedsensitivity in both day and night shooting applications. Under low light condition,SSC-E470 series automatically switches the infrared cut filter to a clear dummy filter andchanges to B/W mode. This results in minimum illumination of 0.05 lx which is a drasticimprovement from 0.55 lx in color mode. The refractive index of the dummy filter isadjusted to visible spectrum, considering that there is some visible light even under darkcircumstances in the majority of cases. Therefore, if only infrared illuminator isavailable as light source, the object will become out of focus with standard lens. Thereare some near-infrared compatible lenses available from several manufacturers includingCosmicar to avoid it.
State-of-the-Art SuperExwaveTM Technology
SSC-E470 Series incorporates a newly developed 1/3-type CCD with SuperExwaveTM technologythat achieves extremely high sensitivity levels and produces high quality images. This CCDimager provides a minimum illumination of 0.55 lx at F1.2, enabling cameras to captureclear and detailed images even under low light conditions. What's more, these camerasreproduce images with a high picture quality of 380,000 pixels (SSC-E473) / 440,000 pixels(SSC-E473P/E478P) and have an excellent S/N ratio of more than 50 dB.
Newly developed innovative DSP Technology
Unlike conventional DSP's, the newly developed DSP technology employed in these camerasincreases the horizontal resolution attainable by the CCD. Thanks to a combination of thisDSP technology and the SuperExwave CCD technology, these cameras offer a high-horizontalresolution of 540 TV lines, providing amazingly clear and detailed images.
Slim and Stylish Design
These slim and lightweight color cameras can easily be installed in places where space islimited and where installation was previously difficult for larger cameras. A stylish rearpanel cover and transparent lens cap come as standard on these cameras so that they willnot detract from the natural décor of the room in which they are installed.
