Comparison of major performance parameters

Common ground
​

1. Body size and LVDS
SONY FCB-EV9520L and the previous 7 series FCB-EV7520, FCB-EV7520A, FCB-EV7500 HD camera movement modules, the biggest common is to have the same body size and mutually compatible LVDS output pin definition, This design allows users to upgrade or update iterations using FCB-EV9520L without large-scale changes to the original installation environment or equipment, and users can directly connect FCB-EV9520L to the original system without changing the original signal transmission line and interface, achieving seamless docking. It not only simplifies the upgrade process, but also reduces the upgrade cost and maintenance difficulty.
​
2. 1080P/60FPS
Secondly, in terms of image quality, SONY FCB-EV9520L and FCB-EV7520, FCB-EV7520A, FCB-EV7500 are high-definition integrated cameras, the resolution is: 1920 x 1080, image format up to 1080P/60FPS, can meet the security monitoring, drones, video conferencing, medical equipment, industrial testing and other industries to meet the needs of high-definition picture quality.
​
The high frame rate of 1080P/60FPS not only provides a more smooth and coherent video picture, but also helps to capture more details in high-speed motion or dynamic scenes, improving image quality and effect.
​
3. 30x optical zoom
The same 30x optical zoom of the SONY FCB-EV9520L as the FCB-EV7520, FCB-EV7520A and FCB-EV7500 ensures that clear, stable images can be captured at different distances without compromising image quality.
​

difference
​

1. Sensor
​
SONY FCB-EV9520L and FCB-EV7520, FCB-EV7520A, FCB-EV7500, although the sensor size is 1/2.8 “, but due to the different technical structure of the sensor, they are different in performance.
​
(1) FCB-EV7500, Exmor CMOS sensor, belongs to the front lighting structure, has the characteristics of high speed performance and low noise.
​
(2) FCB-EV7520 and FCB-EV7520A, Exmor R CMOS sensors, belong to the back-lighting structure, on the basis of the advantages of front-lighting high-speed and low noise, but also have higher sensitivity, double noise reduction and overcome the color mixing problem, making the image color more pure and accurate, thereby improving the image quality.
​
(3) FCB-EV9520L, STARVIS2 CMOS sensor, belongs to the backlighting structure, which is a new low light sensor technology launched by SONY, with higher sensitivity and color reduction ability, sensitivity increased by about 2 times, can provide better image quality in low light environment, with better starlight night vision function. Color images can still be output at 0.01Lx low illuminance, and the lowest illuminance can reach 0.00008Lx.
​
Thanks to the CMOS sensor of SONY STARVIS2 technology, the FCB-EV9520L shows better sensitivity and low illumination performance, making it able to maintain excellent image quality at night or in low light environments, providing reliable visual support for a variety of application scenarios.
​
2. image stabilisation
The FCB-EV7520, FCB-EV7520A and FCB-EV7500 use electronic anti-shake technology.
​
The FCB-EV9520L captures high-precision video with reduced blur, even in harsh environments with strong vibration, thanks to greatly improved blur suppression and image stabilization. Compared with traditional electronic stabilization, a larger correction area is used to suppress strong image jitter. The performance is particularly outstanding in areas of intense turbulence such as intelligent transportation, shipborne systems, bridge monitoring and drone aerial photography.
​
3. wide dynamic
Wide dynamic range refers to the camera’s ability to capture details in the brightest and darkest parts of the same scene.
​
SONY FCB-EV9520L and FCB-EV7520, FCB-EV7520A, FCB-EV7500 four models have wide dynamic function.
​
The SONY FCB-EV9520L and FCB-EV7500 have a higher dynamic range than the other two models: 130dB. It can handle scenes with strong light contrast more effectively, ensuring that details in both light and dark areas are clearly presented. Significantly improves camera performance in complex lighting environments.
​
4. low latency mode
Only the SONY FCB-EV9520L and FCB-EV7520A have a low latency mode, which can process images at the fastest transfer speed and achieve image output with smaller delays. This is very useful for application scenarios that require high real-time performance, such as real-time surveillance, video broadcast, drone aerial photography, and so on.
​
5. the center of the lens
Compared to the FCB-EV7520, FCB-EV7520A and FCB-EV7500, the center of the SONY FCB-EV9520L lens is shifted downward by about 2mm. If the application scenario does not have strict requirements for the lens position, and the space allows for fine tuning, Then you can usually seamlessly upgrade to FCB-EV9520L, such as security monitoring, video conferencing, etc.
​
6. Other functions
FCB-EV9520L, as SONY’s new HD integrated movement module, has a unique good optical axis consistency, new three areas, point light source avoidance and distortion correction functions, so that it shows more excellent performance and a wider range of applications. This is unmatched by the FCB-EV7520, FCB-EV7520A and FCB-EV7500.
​
To sum up, FCB-EV9520L and FCB-EV7520, FCB-EV7520A, FCB-EV7500 has the same body size and LVDS output definition pin, and FCB-EV9520L uses more advanced hardware composition and software technology. It provides more reliable and efficient solutions in various application scenarios. The most efficient and cost-effective alternative to FCB-EV7520, FCB-EV7520A and FCB-EV7500.
