Sony’s new 4K network camera, model SNC-VB770, offers the highest sensitivity in its class - under 0.004lx, ISO 409600. The new model combines ultra-high sensitivity with 4K resolution and advanced networking capabilities to give video professionals more flexibility to capture details even in extreme low-light conditions.
High resolution and sensitivity
The new SNC-VB770 camera achieves high resolution and sensitivity, in addition to low noise due to its image processing and full-frame 35mm Exmor sensor – all developed by Sony.
The sensor captures significantly more light with low noise than conventional camera sensors to realise drastic improvements in sensitivity. The result is low light performance in nearly pitch-black environments beyond the capabilities of human eyes.
The SNC-VB770’s supports Sony’s high performance E-mount lens series which includes a variety of lens options from wide angle to telephoto, allowing easy integration into a range of video capture applications, including surveillance such as city, transportation, police, port and utility.
“The SNC-VB770 builds on Sony’s image sensor strengths and applies this expertise to new applications in the commercial video capture realm,” said Roger Lawrence, Video Security Product Manager at Sony Professional Europe. “Low-light conditions don’t only occur at night. They exist 24/7 in museums, zoos and any number of municipal and commercial areas. This new camera and our expanding line of 4K network models give users more options for meeting their demanding capture requirements.”
4K resolution and area-specific noise reduction
With the exceptional detail provided by 4K technology (4 times the detail of full HD) security professionals, for example, can expand their wide area surveillance and still capture, magnify and examine the smallest parts of a scene like a face or a car license plate number – all with a single camera.
The new camera uses area-specific noise reduction to selectively divide images into areas based on patterns (such as edges, textures and evenly coloured areas like blue skies) to efficiently reduce noise. In addition, detail reproduction technology further enhances image quality.
E-mount lenses are optimised to maximise the performance of the 35 mm full-frame sensor, keeping resolution high across the entire image area from the centre to the lens periphery.
Intelligent Cropping feature
The camera’s Intelligent Cropping feature lets users capture a full view while cropping images in its native 4K resolution from multiple images at the same time, with either 3 or 5 simultaneous video streams.
Intelligent Cropping has two modes, static and dynamic. Users can select “static” to see multiple specific areas in one scene. They can capture an overview image and the details of the cropped areas at the same time. “Dynamic” mode uses the intelligent motion to detect, crop and track moving objects automatically.
Intelligent Scene Capture automatically adjusts and adapts picture quality (brightness and colour) depending on time, weather and lighting conditions. The camera also allows users to customise picture parameter presets for the best settings. Multiple picture configurations can be saved and switched either manually (using the Picture Profile mode) or according to schedule (Picture Profile Scheduler) to ensure the best picture quality day or night.
