Sony FCB-ER8550 20x 4K CMOS w/ Genlock

The FCB-ER8550 features Sony's Super Resolution Zoom (SRZ) technology, enabling it to deliver the equivalent of 30x optical zoom at full 4K resolution. The FCB-ER8550 also features compact form factors (50mm x 60mm x 93.3mm) for space-constrained environments; the FCB-ER8550 features an external synchronization function that effectively synchronizes multiple cameras filming.


Super Resolution Zoom

  • FCB-ER8550 has 30x zoom, in sync with an optical 20x zoom lens.
  • "By Pixel Super Resolution Technology" suppresses image degradation when an image is enlarged, providing excellent images at their original resolution.

4K @30fps images

The 1/2.5-type Exmor R CMOS image sensor successfully brings superb 4K (QFHD) picture quality. The FCB-ER8550 produces high-quality images using Sony's latest sensor technology in low-light conditions. 

20x optical zoom

The high-quality lens features an F2.0 maximum aperture and a 20x optical zoom range. Zoom operation is ideal for smooth, rapid transitions from wide area coverage to detailed close-ups in security and surveillance applications.

Image stabilizer

The Sony FCB-ER8550 features a built-in image stabilizer function that counters low-frequency vibrations. Applications include traffic monitoring and outdoor surveillance, where exposure to the elements can lead to shaking, such as on a bridge or tall structures. It ensures no compromise in image size and blur reduction.

Advanced 2D/3D Noise Reduction

Noise reduction technology filters noise from the images for precise results, especially in low light conditions. Noise reduction settings range from five different levels, and it suits a wide range of operating conditions.


The benefits of optimized picture quality in changing light conditions are frequent challenges in round-the-clock security operations. The Sony FCB-ER8550 operates effectively in lighting levels low as 0.21lx (50%, ICR off, Slow Shutter 1/4s, when High sensitivity is off) and 0.06 lx (50%, ICR off, Slow Shutter 1/4s, when High sensitivity is on). 

Visibility Enhancer and De-fog

This feature enhances Picture quality dynamically and adaptively on a pixel-by-pixel basis while continuously adapting to the scene within the given dynamic range. The de-fog features in the Sony FCB-ER8550 allow more precise viewing in foggy or misty settings.

Auto ICR (Auto IR-cut Filter Removal)

The Sony FCB-ER8550 automatically switches from day to night mode in low light conditions; removing the IR-cut filter boosts sensitivity for clear pictures in low-light conditions.

Wide range of features for versatile operation

The Versatile Sony FCB-ER8550 camera operation ensures a wide range of functions and adjustments, including White Balance modes; Picture effects (E-Flip, Black & White, Mirror Image, Gamma, Color Enhancement); Privacy Zone Masking; Picture freeze; Shutter Priority; Iris Priority (26 steps) Slow AE response, etc.
