The product line of Super LoLux HD2 of JVC company for the systems of security video surveillance was filled up in November, 2014 by highly sensitive VN-H237BU (EX) and VN-H257U (EX) IP video cameras which have the vandal proof body of dome type with a class of protection IK10 and are expected video filming in premises. Both innovations create the image with permission of Full HD at osveshchennost to 0.042/0.012 lx and transfer on network up to 3 video flows in H.264/MPEG-4/M-JPEG. It should be noted that these dome cameras can work under control of corporate software of Super LoLux HD or ONVIF/PSIA - compatible software of other developers, support electronic PTZ functions, are equipped with the detector of the movement and have the slot for the memory cards SDHC.
The VN-H237BU/VN-H257U (EX) body corresponds to a class of shock resistance IK10 (20 J) and reliably the varifocal lens protects electronics and 3-9 mm from mechanical influences. Thanks to it, new products can be set in premises where the probability of acts of vandalism is high. At installation on objects of the big area these vandal proof dome cameras allow to implement electronic autopatrol with programming PT пресетов and a digital zoom (up to 8 krat). Power supply of both dome devices is performed on SWARM technology, and the VN-H257U (EX) model besides supports a power supply via the adapter of 24 V of alternating current from the power supply network.
The centralized administration of devices and the video surveillance system using VN-H237BU (EX) and VN-H257U (EX) video cameras can be performed by means of a corporate VMS product of JVC SuperLoLux HD which provides automatic search of IP devices in networks, setup of their network addresses, etc., or other software conforming to the ONVIF and PSIA standards. Via interfaces of these programs dome cameras of observation allow to configure image resolution from 1920х1080 px. (Full HD) up to 320х240 px. in the H.264 and M-JPEG formats and from 640х480 px. up to 320х240 px. in MPEG-4 and frame rate up to 30 fps at any permission, etc. Besides, new dome devices support remote setup of image quality under external light conditions and also algorithms of their reaction to disturbing events.
Unlike the majority of analogs, VN-H237BU (EX) and VN-H257U (EX) video cameras have high photosensitivity, provide an exact color rendition, picture contrast and effective video filming even in bad light conditions. Thanks to application of a highly sensitive matrix and corporate technology of image processing Super LoLux HD2 these dome cameras are capable to broadcast informative color video at osveshchennost to 0.05 lx, and black-and-white — up to 0.042/0.012 lx, respectively. Besides, new dome models have the systems of high dynamic range and three-dimensional noise reduction increasing detailing of the picture and correctness of work of analytical applications.
Selecting video cameras from a line of Super LoLux HD2 and the VR-X1600U, VR-X3200U and SuperLoLux HD NVR video recorders of production JVC it is possible to create effective video surveillance systems with required number of channels, wide functionality and different means of protecting of video from viewing by strangers. It should be noted that network dome cameras of this line are capable to transfer in parallel to 3 flows of video in the M-JPEG, MPEG-4 or H.264 formats (High and Main Profile) and allow to select bitrate from range from 64 kbps to 20 Mbps. Dome devices perform local data storage on SDHC standard memory cards.
Each video camera from the Super LoLux HD2 series using the video detector of the movement and the system of detection of external influences will be able timely to register unauthorized actions in a video control zone. Unlike VN-H237BU(EX), the VN-H257U (EX) dome cameras are supplied with the audiochannel, the detector of a sound and 2 disturbing inputs and output for connection of the external sensor / actuator which algorithms of operation are set through the built-in menu. At IP connection violation both dome models can record video on the built-in memory card, and after recovery of contact with the video recorder or the server transfer the written video to archive.
