半球型1/3" 650條超高解析攝影機


The SSC-N21 is a super high resolution analogue minidome camera. It gives security-conscious companies the reliable surveillance they need, even within the confines of a strict budget.

The camera offers superb quality images through its analogue-maximum 650 TV lines horizontal resolution and its high sensitivity (Colour: 0.15 lx / B/W: 0.01 lx, F1.2, 50 IRE), achieved by a 1/3-type "EXview HAD CCD II" sensor and Sony's new digital signal processor, "Effio-E". 

From its compact body, the SSC-N21 can scan a very wide area with its new three-way hinge and 3.7x variable focal length, offering a horizontal angle of view of 99.5" to 27.4".

The SSC-N21 utilises Sony's latest image technology to enhance scenes to their maximum potential for analysis. Electronic Day/Night capability ensures images are optimised, no matter what time of the day it is. Automatic Tone Reproduction Lite (ATR-Lite) offers good image detail in scenes of variable luminance, whilst i-Back Light Compensation (iBLC) improves detail in images affected by strong light sources. Automatic Tracing White (ATW) balance even adjusts the camera's white balance to adapt to sudden changes in lighting conditions.
