Sony Camera Information

Introduction of Sony FCB-EV9520L features: pixels

Definition of pixels

Pixel refers to the number of photosensitive cells on the image sensor, which is a unit of measure for image resolution. Each pixel represents a point in the image, which records the intensity and color of light.




The number of pixels in a camera determines the clarity and detail of the image. Typically, the higher number of pixels brings the higher image resolution and the better detail performance. Common specifications of Sony zoom camera blocks include 2 mega pixels, 4 mega pixels, 8 mega pixels, 12 mega pixels, 20 mega pixels, etc. Sony’s new product FCB-EV9520L uses a 1/2.8-inch sensor with an effective pixel up to 2.13 mega.


Relationship between pixels and other specifications

Pixels are closely related to other specifications of the camera. What functional specifications of Sony FCB-EV9520L are related to pixels?


Resolution: The number of pixels determines the resolution of the camera, that is, the clarity and detail performance of the image. A higher pixel count means higher resolution, which can capture more details and subtle changes. For a 2-mega pixel camera, the resolution can be 1600×1200 or 1920×1080, and Sony FCB-EV9520L belongs to the latter.


Digital zoom: The higher pixel count allows the camera to achieve greater magnification through the digital zoom function without losing too much image quality. The 12x digital zoom of Sony FCB-EV9520L is very useful for scenes that require magnifying details for observation and analysis.


Relationship between pixels and other specifications


Low-light performance: A higher pixel count usually means a smaller photosensitive unit size, which can have an impact on the camera’s low-light performance. Smaller photosensitive unit size may result in more noise and poorer low-light imaging. Therefore, when choosing a high-pixel camera, you need to pay attention to whether its low-light performance meets your needs. Sony FCB-EV9520L has a 2D/3D noise reduction function, which can effectively reduce noise, and uses a STARVIS2 CMOS sensor to output more realistic color images even in low-light environments.


Storage requirements: A higher pixel count means that the data of the image will also increase, and therefore it has an impact on storage requirements. Higher pixel counts may require greater storage capacity to store image data, so storage requirements and the capacity of the storage device need to be considered when selecting a camera.


Pixels and Monitoring

For surveillance cameras, the demand for the number of pixels is relatively low. Generally, 400,000 pixels can meet basic monitoring needs. This is because the main purpose of surveillance cameras is to capture key scenes and dynamic changes, rather than pursuing high resolution and detailed performance. Therefore, in general surveillance scenarios, 400,000 pixels are enough to meet the needs.


Pixels and Monitoring


However, in some special surveillance environments, such as those that require higher-definition detail analysis or longer-distance target recognition, HD cameras may be more suitable. FCB-EV9520L can provide higher image quality and more detailed performance capabilities to meet these special needs.


It should be noted that the number of pixels is not the only indicator of image quality. There are other factors such as image sensor quality, lens quality, image processing algorithms, etc. that will also influence the quality of the image. Therefore, when choosing a camera, in addition to focusing on the number of pixels, you should also consider other specifications and functions to get the camera that best suits your needs.
