Description:
High Resolution and Wide Dynamic Range Combined in a Small, Block Color Camera! Sony is enhancing its line-up of block cameras with the introduction of its new D version wide dynamic block cameras. The SONY FCB-EX490DP high resolution camera incorporates a ¼-type EXview HAD™ CCD with Advanced Digital Signal Processing to reproduce clear detailed images at an extremely high horizontal resolution of 530 TV lines. The SONY FCB-EX490DP features an 18x optical zoom lens. Feature-rich and coupled with clear and detailed images the SONY FCB-EX series of color block cameras are ideally suited for monitoring applications that demand high performance.
SONY FCB-EX490DP FEATURES:
* Powerful and Versatile Zoom Capability/Wide VIewing Angle
The Sony FCB-EX490D camera incorporates an 18x optical zoom lens.
* High-Resolution Images
Combining a newly developed DSP with a 1/4-type EXview HAD CCD the Sony FCB-EX490D camera achieves a high horizontal resolution of 530 TV lines and outputs amazingly clear and detailed images.
* Wide Dynamic Range
This new Sony FCB-EX490D camera incorporates an advanced backlight compensation technology that improves the camera's dynamic range by 128 times compared to previous FCB C series cameras resulting in clear image reproduction. This camera captures the same image twice - first with a normal shutter speed and then with a high shutter speed. The dark areas captured a normal shutter speed and the bright areas captured at high shutter speed are then combined into one image using an advanced DSP clearly reproducing the original scene. Wide Dynamic Range is ideal for lobby camera applications where the camera is exposing both people indoors and outdoor parking lot areas within the same picture.
* Video Motion Detection
Within a screen divided into 12 horizontal and 8 vertical blocks the Sony FCB-EX490D camera can detect a change in luminance within designated areas (up to 4 areas) and specifies its position.
The video motion detection function is useful for unattended monitoring/recording found in security applications. The camera is viewing a fixed position and is able to record when an intruder is detected. An alarm signal is output via the camera's control interface using the VISCA™ protocol.
* Slow AE Response Function
The new Sony FCB-EX490D camera is equipped with a slow AE response function to automatically slow the rate at which camera exposure levels change. The rate can be set up to 32 times slower than when Full-Auto AE or Priority (shutter/iris) modes are selected. This function is useful when monitoring areas in which lighting conditions change abruptly. For example if the camera is used to monitor the flow of nighttime traffic when vehicle headlights are pointed directly towards it the camera's exposure level is reduced slowly. This can allow users to monitor and identify crucial parts of the image that surround the headlights such as the car's license plate or the driver's face.
* Advanced Spherical Privacy Zone Masking with Mosaic Effect
In addition to conventional color masking unwanted or prohibited areas within an image can be masked using a mosaic effect. A maximum of eight masking areas can be displayed on the monitoring screen. Also when this block camera is used with a Pan/Tilt/Zoom (PTZ) camera system masked areas are interlocked with PTZ movements regardless of the camera angle or even if it is circling. Up to 24 masking areas can be preset in the entire viewing range of the PTZ camera.
* SMART (Sony Modular Automatic Lens Reset Technology) Lens Control
The new Sony FCB-EX490D camera incorporates SMART Lens Control technology that monitors the focus position of the lens during zooming and automatically compensates for any mechanical misalignment that may occur over long periods of continuous usage. With the introduction of SMART Lens Control periodic lens initialization is no longer required during continuous 24-hour operation.
* Multi-Line On-Screen Display
Up to eleven lines with 20 characters per line can be displayed on the monitoring screen using VISCA commands. Users can freely display captions on the screen such as monitoring location camera name alarm messages and providing operators with a user-friendly interface.
* Picture Freeze
The Sony FCB-EX490D camera is equipped with a Picture Freeze function that allows for the output of a still image while the camera is panning tilting zooming focusing initializing the lens or performing preset operations. For example the camera will out a still image before it begins to pan tilt or zoom. Once the operation is completed the camera continues to display images so that unnecessary images are not displayed.
* Auto IR-Cut
