The Cisco 2611 dome camera is equipped with the 1/3-inch CMOS sensor with WDR to 120 dB, h3.6 the zoom lens which is switched-off by the IK-filter and works in the day/night modes at osveshchennost up to 0.65/0.08 lx. It can broadcast on network one or two of a video flow with the permission to Full D1 (720x576 px.) in the H.264, MPEG-4 and/or MJPEG formats at the frame rate of 25 fps. Besides, this surveillance videocamera is supplied with the detector of the movement, an audio-input and output, and can receive a power supply from a source of 12 V a post. current or on SWARM technology. For work as a part of the systems of security observation of the Cisco video camera are integrated into specialized software of Video Surveillance Manager of the Cisco brand and third-party developers.
The new video camera is created based on a 1/3-inch CMOS matrix and uses the modern processor of video signal processing thanks to which Cisco 2611 can create the image with the permission to Full D1 (720x576 px.) at a speed of 25 fps. Due to existence of functions of automatic white balance control, compensation of a counter flare and autoexposure and also broad dynamic range (WDR) reaching 120 dB, this surveillance videocamera creates the image with high rates of brightness, contrast, sharpness and exact transfer of colors, without allowing "draining" of objects in the darkened areas of a frame.
Cisco 2611 supports double-stream video broadcasting and uses 3 codecs — H.264, MPEG-4 and MJPEG. At this video in MPEG-4 format can go for the current observation and record with high quality. Video in H.264 is optimal for transfer on networks with limited bandwidth and also for increase in write time in a videoarchive as this codec is more economic than MPEG-4. For transfer of disturbing video (for example, on the FTP server) it is recommended to use a video flow in M-JPEG. In addition to it, the surveillance videocamera is supplied with audio an input and output, uses G.711 and G.726 audiocodecs and supports sound transmission modes to a floor - and a full duplex.
The producer recommends to exercise setup and control of Cisco 2611 using software of Cisco Video Surveillance Manager. Software has the client-server architecture and includes the module VS Media Server for management of video flows, the module VS Operations Manager for remote configuring of network equipment, etc. which provide to the operator of observation system a full range of functions for watching the current video, its record and work with archive video. In addition, the surveillance videocamera has an open architecture of internal software and is embedded in software applications of third-party developers.
Installation of the new video camera on an object is most asked. Construction of the Cisco 2611 body allows "cut" it in a suspended (falseness) ceiling without use of additional brackets of fastening. At the same time it is possible to select the direction of observation rather precisely using a turning gear of the chamber block from range of corners of 160 °/340 °/200 °. KN22/KN24 developed according to standards of the maximum longitudinal load, the surveillance videocamera belongs to the class of udaroustoychivy. Protection of electronics of the video camera is provided by the metal body and a polycarbonate dome.
Setup of the sector of observation at installation of the dome camera on an object is provided with a varifocal lens with a range of focal distances of 3.3 - 12 mm and an autodiaphragm managed by a direct current signal (DC). At the same time the viewing angle of a lens varies from 24 ° up to 90 ° (in horizontal direction). Thanks to support of the AGC function of a lens, the Cisco 2611 surveillance videocamera regulates and arranges the level of video input signal, allowing to receive the sharp image at weak lighting. Besides, for improvement of image quality in the conditions of variable illumination on an object the video camera executes autoswitching of the day/night modes.
For access restriction to settings and watching video Cisco 2611 uses authentication of users with password protection, the IP-filtering mode for the analysis and blocking of the counterfeited IP addresses, HTTPS enciphering and the IEEE802.1X protocol for safe connection to network. Besides, this surveillance videocamera supports standard network protocols, including DHCP, FTP, HTTP, SMTP, TCP/IP, QoS/DSCP and also protocols of detection Cisco Discovery Protocol and Bonjour zero-configuration discovery which help to identify quickly the network equipment connected to observation system.
