Sony has incorporated 4K images to the range of security technologies with its new SNC-VM772R camera, which combines this resolution with sensitivity in low-light environments and benefits from the backlit Exmor R CMOS image sensor type 1.0, bandwidth optimization features and intelligent scene capture to adopt the best image quality.

Thanks to the exceptional level of detail of 4K technology, professionals in the sector will be able to expand their surveillance area, take snapshots, enlarge them and examine even the smallest detail of an image, like a face or a car license plate, all with a single camera.

The SNC-VM772R camera is particularly suitable for application in urban surveillance environments, means of transport, railway stations, traffic and airports, with flexible and simple installation.

Katsunori Yamanouchi, Vice President, Sony Professional Solutions Europe, points out that "4K technology is the new standard of video surveillance, but 4K image processing is more than just a higher resolution: in addition to expanding the application potential of cameras, is transforming the security and surveillance sector. Higher resolution allows you to cover a wider area, which improves situational awareness and guarantees that nothing will go unnoticed. These benefits enable security professionals to reduce installation and operating costs, since the number of devices that are needed for certain areas is reduced".

The introduction of SNC-VM772R in the security sector "extends Sony's leadership in 4K technology, in both the broadcast and production industries, where our 4K cameras record blockbusters, popular TV shows and major sporting events. Our 4K digital cinema projectors are in cinemas all over the world, and our 4K TVs make content available to consumers", underlines this manager.

In this sense, the company has developed several unique technologies to overcome the challenges of 4K cameras on the market by improving visibility and light sensitivity., along with reducing the bandwidth needed to handle large files with this resolution.

Light sensitivity

Traditionally, a higher resolution has been a detriment in the level of sensitivity in low light. However, the new SNC-VM772R uses an Exmor R type CMOS sensor 1.0 of 20 megapixels and has a sensitivity of 0.1-lx to capture sharp images in light and dark situations.

Backlit structure doubles the light sensitivity of the camera and infrared light source (Go) Built-in improves low-light use and night recording with long-distance visibility.

There are various lighting conditions during the day and night when covering large surfaces, therefore this camera also has a wide dynamic range of 90 dB and 30 Fps, that provides clear and sharp images to improve visibility and recognition capability.

In addition, 2.9x motorized zoom is adapted to the image sensor to maximize video resolution. The lens also has image stabilization and allows you to capture images with reduced distortion.

Flexible settings and optimized transmission

SNC-VM772R uses Sony's unique bandwidth optimization technology that allows users to customize both transmission settings and camera operation. Smart encoding feature reduces storage space and bandwidth consumption by adopting various compression variants depending on the area of interest.

For its part, Smart crop and multi-tracking function offers a panoramic view and allows you to select up to four areas of interest at the same time, so that users can see in 4K resolution only the section of the image they want, while streaming images in Full HD. The result is a reduction in 50% in bandwidth consumption, by reducing the amount of video streamed with 4K resolution and improving the efficiency and orientation of large surface monitoring.

the smart crop function uses two patterns to select the size and number of zones, as well as two modes: Static, to view multiple fixed areas in a scene; and dynamic, to detect moving objects.

Evidence capture allows users to see critical moments in the highest camera resolution, of 20 Megapixel, in snapshot mode, which has a resolution of pixels 2,4 times higher than 4K. In addition, alarms can be issued when movement is detected in certain areas.

Intelligent Scene Capture automatically adjusts and adapts image quality (brightness and color) depending on the time, weather and lighting conditions. The SNC-VM772R camera also allows users to customize the default image parameters to define the best settings between day and night..

In addition, the system offers the ability to store various image settings that can be changed manually (using Picture Profile mode) or according to the established schedule (Picture Profile planner).

Sony expects to have the SNC-VM772R model on the market in the third quarter of 2015, which will be supported by leading VMS providers, as AxxonSoft, Exacq Technologies, Genetec, Genius Vision Digital, Lenel Systems, Milestone Systems, Nice Systems, NUUO, On-Net Surveillance Systems, SeeTec AG and Verint Systems.
