Sony FCB camera block
In SONY FCB-EV series movement, FCB-EV7520 is widely used, but we still have to choose according to our own needs, so it is very important to understand the difference between FCB-EV7520 and FCB-EV7500. Next, Xuan Zhan technology brings you the difference between FCB-EV7500 and FCB-EV7520.
FCB-EV7500 and FCB-EV7520 are two similar models of SONY camera. Most of the parameters and functions are the same. Compared with FCB-EV7500 camera, FCB-EV7520 adopts different image sensors from the past: Backlight CMOS image sensor Exmor R CMOS(FCB-EV7500 uses Exmor high-speed CMOS image sensor), which can achieve high sensitivity, effectively improve the sensitivity and reduce noise, in addition, Using the backlight CMOS image sensor Exmor R CMOS movement has FCB-EV7520/FCB-EV7320/FCB-EV7317 these three types.
In order to improve the high sensitivity performance suitable for night shooting, so that the surveillance camera can shoot clear images in any environment, SONY developed STARVIS (backlight pixel technology for CMOS image sensor for surveillance cameras), the application of this technology of integrated movement FCB-EV7520 and FCB-EV7320 two kinds, The FCB-EV7500 does not have it.
The effective pixels of the sensor are slightly different, both are 2 million pixels, the FCB-EV7500 is about 2.38 million pixels, and the FCB-EV7520 is about 2.13 million pixels.
The minimum illuminance difference, FCB-EV7520 can reach the star level, the minimum illuminance is 0.01lx(F1.6) of high sensitivity, in the night low illuminance environment, can also reproduce the picture, which has a great role in security video surveillance; The FCB-EV7500 does not. In addition, SONY FCB series has the lowest illuminance of the star level of FCB-EV7520/FCB-EV7320/FCB-EV7317 these three movements.
The specific difference between the two parameters can be viewed through the following comparison table of the two parameters organized by Xuan Zhan Technology.
