Detailed explanation of parameter differences between Sony HD movement fcb-cv7500 and fcb-cv7520
Among Sony fcb-ev / CV series movement, the latest fcb-cv7520 with the best configuration is also more and more used in HD applications, but we still have to choose according to our own needs.
Therefore, it is very important to understand the difference between fcb-cv7520 and fcb-cv7500.
Next, xuanzhan technology's Sony FCB series HD integrated movement parameter difference analysis series, What brings you is the difference between fcb-cv7500 and fcb-cv7520 (the difference between fcb-ev7500 and fcb-ev7520).
As Sony's fcb-cv75 series products, most of the parameters and functions are the same.
Compared with the past fcb-cv7500 movement, fcb-cv7520 adopts a different image sensor: back illuminated CMOS image sensor Exmor r CMOS (fcb-cv7500 uses Exmor high-speed CMOS image sensor), which can achieve high sensitivity, effectively improve sensitivity and reduce noise, For a detailed introduction to the technology of these two image sensors, you can see: exmorr & Exmor of Sony camera core module use technology analysis series. In addition, the movement using back illuminated CMOS image sensor Exmor r CMOS includes fcb-cv7520 / cv7320 / cv7317.
In order to improve the high sensitivity performance suitable for night shooting and enable the surveillance camera to shoot clear images in any environment, Sony has developed starvis (back illuminated pixel technology for CMOS image sensor for surveillance camera).
The integrated movement applying this technology includes fcb-cv7520 and fcb-cv7320, but fcb-cv7500 does not.
There are some differences in the effective pixels of the sensor, which are all at the level of 2 million pixels. The fcb-cv7500 is about 2.38 million pixels, while the fcb-cv7520 is about 2.13 million pixels.
In terms of minimum illuminance, fcb-cv7520 can reach the star level, with a high sensitivity of 0.01lx (f1.6) minimum illuminance, and can truly reproduce the picture in the low illuminance environment at night, which plays a great role in security video monitoring; Fcb-cv7500 cannot.
In addition, Sony FCB series has three movements with the lowest illumination of star light level: fcb-cv7520 / cv7320 / cv7317.
The difference in function is that fcb-cv7500 has wide-d function, while fcb-cv7520 does not.
