When sending and viewing video in real time are presented, as a rule, high demands on network bandwidth. For a rational distribution of traffic network video servers network support mechanism of QoS (Quality of Service), which allocates part of the channel in a streaming video of the STS-IPT480. Support for PPPoE (Point-to-Point Protocol over Ethernet) ensures minimal delay and high speed transmission of video and allows you to connect via network video servers ADSL-line or cable modem. Convert analog video signal up to 4 cameras to digital by a processor Arm9, built on the principle of SoC (System-On-a-Chip). Through this network video servers form a high-quality image and transmits it over the network in real time with up to 25 k / s as a quad image of four channels of CIF resolution, or as an image of a selected channel with a resolution up to 720X576 pixels. Thanks to the built-in web server, STS-IPT480 allows you to view digital video on the network through a standard Web browser, Internet Explorer 6.0 and above. Change the settings of the video server can only a user with administrator privileges.
User, not administrator rights, can only view the images in real time and to change the view settings. To connect to the LAN-and WAN-network network video servers are equipped with two network Smartec port 10/100BaseT Ethernet (RJ45). Analog cameras are connected to the STS-IPT480 four composite video inputs, and composite video output via a video server can connect to a monitor for viewing images. Audio Line In and Out devices allow you to organize a two-way audio with the video object. Special attention is paid to the STS-IPT480 protection against deliberate distortion of the video. To do this, network video servers use a technology called Digital Time Code, which exports to all the shots, "watermarks" in the form of the date and time. According to these signs, you can easily determine the exact date and time when the frame was received. In addition to protecting against counterfeit video, this technology helps in the analysis recorded alarm early material.
To work in the video surveillance network video servers are equipped with hardware motion detection and a connector for external alarm sensors. At receiving the alarm STS-IPT480 can send pre-and posttrevozhnye frames specified in the FTP-server, and also activate external alarm devices connected to its alarm outputs. In the supply network video servers STS-IPT480 equipped with Russian-language free software NVR, which supports the simultaneous viewing of "live" video with synchronized audio soundtrack as well as recording and playback of video and audio in MPEG-4. NVR supports all necessary recording modes: continuous, scheduled, motion detection or alarm. Pre-alarm recording the maximum duration of 30 seconds. New network video servers STS-IPT480 already arrived at the warehouse of the company "ARMO-Systems", which is the exclusive distributor of equipment Smartec in Russia and CIS countries, and you can buy them at a retail price of 820 USD, including VAT.
