Dome SNC-DH260 and SNC-DH280 IP cameras. These products are the advanced development of Sony company. In them there is built-in IK-illumination with the range of 20 m and video analytics mechanisms from Sony are implemented.
New IP cameras are constructed on the CMOS sensor of 1/2.8 in size", developed by Sony company on Exmor technology. They provide the video image of the Full HD (1920х1440) format which contracts H.264, MPEG-4 and M-JPEG codecs, with a possibility of the subsequent double-stream transfer. In case of use of algorithm H.264 at permission 1920х1080 frequency with which the image forms reach 30 fps. At compression on MPEG-4 for the same permission frequency is equal to 20 fps, at compression on M-JPEG - 16 fps.
Both new products work in the day/night mode and are supplied with the mechanical IK-filter. The IK-illumination applied in them works at the wavelength of 850 nanometers and has automatic power control. Cameras are supplied with a varifocal lens with the focus changing from 3.1 to 8.9 mm. At such change the horizontal viewing angle is rebuilt from 88.5 to 32.3 °. Upon transition of cameras to the night mode correction of focus is made using the Easy Focus function.
The intellectual analysis of the image (video analyst) based on technologies of Sony is implemented in two new cameras in different scales. SNC-DH260 model is equipped with basic feature set, making DEPA technology, and DEPA Advanced packet including more difficult algorithms is built in SNC-DH280 model. Among the last - calculation of number of objects, intersection of border, emergence and disappearance of objects. In the intelligent detector of the movement which is available in both cameras the number of the false operations connected with oscillating motion in a frame, such as trembling of leaves on trees or ripples on water is minimized.
One more difference of the SNC-DH280 network camera consists that in it two advanced technologies of image processing are used. One of them - View-DR (Visibility Enhanced Wide Dynamic Range - "Broad Dynamic Range with the Increased Visibility"). Thanks to its use the dynamic range of the camera makes 90 dB that allows it to work at the contrast and constantly changing lighting. The second technology - the dynamic system of noise reduction of XDNR (eXcellent Dynamic Noise Reduction). It promotes improvement of image clarity and noise elimination at low illumination.
New cameras conform to the ONVIF standard and can be used in video surveillance systems together with the products of different producers supporting this standard.
Protection of new IP cameras against moisture and dust corresponds to class IP66. Thanks to existence of the built-in heater the temperature range of their work stretches to -30 °C. The body of the camera provides anti-vandal protection. Cameras support PoE technology.
