Thanks to ultra-high sensitivity of ISO 409600*, the SNC-VB770 4K network camera features top levels of minimum illumination of less than 0.004 lx - to capture exceptionally detailed 4K/30 fps colour video, even at night and in similar extreme lighting environments.
The SNC-VB770 4K network camera achieves this illumination by using its highly-sensitive 35 mm full-frame Exmor sensor, optimised E mount lenses to maximise the performance of the sensor, and its signal processing engine. This enables the camera to capture crisp, clear 4K/30 fps colour video with much less noise in extreme low-light conditions.
The new camera enables smooth 4K/30 fps colour video in almost pitch-black conditions such as night-time starlight or indoors with a poor lighting source when it is a challenge for the human eye to see the object. Also, the camera captures blur-less images with high-speed electronic shutter so that it gives users ability to track letters (characters), numbers and human facial expression clearly in poorly-lit conditions.
This camera is the first to adopt an E mount FE lens** within our existing network camera line-up. The wide-range of high-quality interchangeable lenses used for consumer digital cameras and professional camcorders gives users the flexibility to adjust the viewing angle to fit various environments and applications. It also maximises the benefits of 4K resolution, allowing detailed analysis of specific areas in a scene, together with a wide-area situational overview.
The SNC-VB770 4K network camera provides smart analytic functions to enable more efficient, cost-effective operation in a wide range of video monitoring applications. Intelligent Tracking plus Multi Tracking can recognise and dynamically track multiple subjects in separate windows, together with its wide-area situational overview. Intelligent Coding captures selected areas of interest in maximum detail, while reducing bit-rates in the other areas of the image to save network bandwidth. Intelligent Scene Capture automatically selects the optimum picture settings responding to environments such as weather, time, and lighting conditions to provide optimum picture quality for any scene, day or night.
*Standard ISO 100–102400, expandable to 50–409600
**Compatible E mount FE lenses include the SEL35F14Z (35 mm, F1.4), SEL35F28 (35 mm, F2.8), SEL28F20 (28 mm, F2.0), and SEL55F18Z (55 mm, F1.8).
Features
Ultra-high sensitivity of ISO 409600* captures clear colour video even in near darkness
Thanks to the ultra-high sensitivity of expandable ISO 409600, the SNC-VB770 features a minimum illumination of less than 0.004 lx to capture exceptionally detailed 4K/30 fps colour video, even at night and in similar extreme lighting environments.
The SNC-VB770 uses the 35 mm full-frame Exmor sensor, which is developed based on Sony’s most advanced image processing technology. The sensor captures significantly more incident light than conventional camera sensors to bring drastic improvements to the sensitivity.
The camera also uses a Sony-developed image processing engine to achieve extremely high sensitivity and low noise at the same time. Area-specific noise reduction selectively divides the image into areas based on patterns (such as edges, textures and evenly coloured areas like blue skies) to efficiently reduce noise and improve image quality. Detail reproduction technology helps to accurately depict details with a more natural sense of dimension.
E mount lenses maximise the performance of the 35 mm full-frame sensor, keeping high resolution across the entire image area from the centre to fringe.

Overview and close-up at the same time with Intelligent Cropping
Intelligent Cropping gives a wide area situational overview of the whole scene and a closer view of specific areas of interest at the same time. Operators can see the whole scene with Full HD resolution, plus up to four VGA cropped image areas. This allows more efficient management of network bandwidth, reducing data storage requirements by up to 50% compared with conventional solutions. In addition, Multi Tracking can recognise and dynamically track multiple subjects in these separate windows. This can reduce the risk of missing suspicious activity, letting operators see unidentified subjects as cropped images whenever they come into the frame.
Maximum detail where it matters with Intelligent Coding
Intelligent Coding optimises efficient management of network bandwidth while maintaining 4K resolution where it’s needed. It gives selected of-interest areas maximum detail, while reducing bit-rates in the other areas of the image to save network bandwidth by up to 50% and minimise storage costs compared with conventional network cameras.
Best picture quality around the clock with Intelligent Scene Capture
Enjoy the best picture quality in any scene, any time of day or night without adjusting camera settings. Intelligent Scene Capture automatically selects optimum picture settings responding to environments such as weather, time, and lighting conditions and providing the best picture quality for the scene. Picture settings can also be adjusted manually, or set according to time schedules.
