To better meet the market’s growing demand for superior imaging performance, Sony has launched its new camera block, the FCB‑EV9520L. Equipped with Sony’s brand‑new STARVIS 2 CMOS sensor and proprietary ISP (Image Signal Processor), and fitted with a 30× optical‑zoom lens, it is a color camera module with enhanced performance. Within Sony’s product lineup, the FCB‑EV9520L and FCB‑EV7520 & CV7520 are two autofocus camera products with similar functionalities, which play vital roles in security surveillance, UAV applications, medical equipment, video conferencing and other fields. What functional‑parameter differences exist between the FCB‑EV9520L (http://www.cmr‑cctv.com/gaoqingxilie/61‑430.html) and FCB‑EV7520 & CV7520? Kaimorui’s technical brief is presented below.

Functional‑Parameter Comparison Between FCB‑EV9520L and FCB‑EV7520 & CV7520

1. Image Sensor

1. SONY FCB‑EV9520L: 1/2.8‑inch STARVIS 2 CMOS sensor (approx. 2.13 million effective pixels)
2. FCB‑EV7520 & CV7520: 1/2.8‑inch Exmor R CMOS sensor (approx. 2.13 million effective pixels)

Though both sensors deliver around 2.13 million effective pixels, the STARVIS 2 CMOS sensor deployed in the FCB‑EV9520L represents Sony’s low‑light‑sensing technology. It features larger pixel size and higher photosensitivity to deliver improved image quality under dim‑light conditions. Thanks to the STARVIS 2 sensor, brighter and sharper footage can be captured for night‑time surveillance and low‑light scenarios, substantially boosting surveillance‑system performance.

Therefore, the FCB‑EV9520L delivers superior starlight‑grade night‑vision performance. It can output color images even under illumination as low as 0.01 lx, with a minimum illuminance reaching 0.0008 lx. It also supports infrared night vision to capture crisp imagery in dim or total darkness and restore colors as faithfully as possible, earning it the reputation of a “black‑light camera”.

2. New Three‑Zone Functions

1. FCB‑EV9520L: Supports regional auto‑exposure, regional auto‑focus and regional auto‑white‑balance
2. FCB‑EV7520 & CV7520: Not available

As Sony’s new high‑performance camera block, the SONY FCB‑EV9520L provides regional Auto‑Exposure (AE), regional Auto‑Focus (AF) and regional Auto‑White‑Balance (AWB). It optimizes designated zones within the frame. Users can fine‑tune critical image areas according to application‑specific requirements. The FCB‑EV9520L detects and adjusts target regions in real‑time, and automatically modifies parameters responding to variations in lighting, focus and color temperature, so as to achieve optimal exposure, focus and white‑balance, yielding more accurate, sharp and lifelike images.

3. Super Image Stabilization

1. SONY FCB‑EV9520L: Two super‑stabilization modes: Super and Super+
2. FCB‑EV7520 & CV7520: Standard‑grade image stabilization

Compared with the FCB‑EV7520 & CV7520, the FCB‑EV9520L offers unmatched super image stabilization with Super and Super+ working modes. When Super mode is activated, high‑performance electronic‑stabilization algorithms effectively mitigate image shake induced by camera‑body vibration or external disturbance, preserving high definition alongside stable footage.

Super+ builds upon Super mode with stronger anti‑shake capability. This mode suits harsher vibration‑prone environments such as onboard vehicle systems, bridge‑mounted installations and ship‑borne camera applications.

4. Optical‑Axis Consistency

The FCB‑EV9520L achieves better optical‑axis consistency than the FCB‑EV7520 & CV7520, maintaining optical‑axis alignment across varying focal lengths and fields‑of‑view. Consistent focus and image quality are guaranteed whether shooting in wide‑angle or telephoto positions. This advantage generates more precise, uniform and high‑quality output, making the module excel in use‑cases demanding strict optical‑axis consistency.

5. Physical Dimensions and Weight

The SONY FCB‑EV9520L shares identical physical dimensions with the FCB‑EV7520 & CV7520, yet it weighs 238 g — 17 grams lighter than the 255‑gram FCB‑EV7520 & CV7520. This brings notable benefits for weight‑sensitive sectors such as UAV systems.

Summary

While both the FCB‑EV9520L and FCB‑EV7520 & CV7520 apply to security surveillance, UAVs, video conferencing, medical devices and other industries, the FCB‑EV9520L demonstrates overall better performance. Furthermore, its super image‑stabilization and excellent optical‑axis consistency equip it to cope with harsh external conditions in ship‑borne systems, intelligent transportation, bridge monitoring, onboard vehicle installations, offshore operations and other sectors.
