High sensitivity IP dome cameras from Sony

Sony Europe, ISS Division : 14 May, 2008  (New Product)
Megapixel cameras from Sony feature flexible lighting response and built in motion detection
At IFSEC 2008, Sony built on its range of intelligent, IP-based cameras with the launch of its first MegaPixel designs - the SNC-DM110 and SNC-DM160, which are suitable for semi-protected outdoor environments and the SNC-CM120, Sony's first fixed-position CS-Mount security box camera with MegaPixel resolution.

Designed specifically to meet the high-performance needs of today's security industry, each of these 1.3 MegaPixel cameras uses Sony's advanced complementary colour progressive scan CCDs with Sony ExwavePRO Technology and Light Funnel Function (binning technology). Unlike conventional progressive scan CCD imagers, this complementary colour filter technology provides increased levels of light sensitivity needed to achieve optimal performance from the camera optics of today's fixed-type MegaPixel systems. Light Funnel technology can be activated automatically in response to surrounding light conditions or on a pre-specified time schedule.

"ExwavePRO and Light Funnel technologies give Sony's fixed-type MegaPixel cameras the capability to output extremely clear and detailed images that deliver bright, high-resolution in even the most challenging lighting environments," explained Simon Nash, Senior European Marketing Manager, NVM/CCTV. "Light Funnel Function combines 4 pixels into 1 pixel, making the cameras four times more sensitive so they can deliver focused images without distortion in both day and night-time environments. As such they are ideally placed for building entrances and car parks, where detailed images such as faces and car registration plates are required. This is particularly true of the more hard-wearing SNC-DM160 model."

The SNC-DM160 and SNC-DM110 provide high resolution images of 1280 x 960 even at wide viewing angles of over 100 degrees. This feature will lend itself particularly to Sony's outdoor venue customers, and wide-area sites such as stadiums, public buildings, city centres and parks. A Ball-Joint Lens Mount mechanism means the lens can be rotated freely in any direction, so unlike conventional cameras, it takes only one action to adjust the pan and tilt angles.

The sturdy SNC-DM160 features a built-in heater and vandal-resistant polycarbonate dome and aluminium die-cast housing to offer IP66 ingress protection. The SNC-DM110 comes with a 2.8-10mm, 3.6x varifocal lens with minimal illumination of less than 3lx at F1.3, and less than 1lx at F1.3 with binning function. It also offers users up to 16 presets, advanced motion detection, a microphone input and line out and Power over Ethernet. The SNC-CM120 and SNC-DM160 are similarly equipped, with the SNC-CM120 camera also featuring a 1/3-inch complementary colour progressive scan imager.

Additional features for the new cameras include a Night Mode setting that provides clear images even when monitoring objects during challenging settings such as dusk and dimly lit environments; variable gamma settings that help to capture high-contrast images; bi-directional audio options; and a slow shutter mode for additional bright image output. The cameras also feature selectable compression formats that include both MPEG-4 and JPEG, and take advantage of high frame rates of up to 30 fps at VGA settings.

Sony has built on the intelligent functionality of its video security products by utilising its unique Distributed Enhanced Processing Architecture (DEPA) technology, which is enhanced by an in-built Intelligent Motion Detection function. This can initiate alarms based on specific movements, minimising false alarms.
