IP solutions: Cisco cameras.
Cisco 2500 Day-Night Network Camera with WDR and Resolution Up to D1 at 25 FPS
Cisco is a global leader in the development of network technologies, production of equipment and solutions for the creation of local and global IP networks, IP telephony and telecommunication systems, which are used by businesses of any scale in almost all sectors of the economy. Since 2008, the company has begun to develop a new direction for it — IP video surveillance technologies and produce wired and wireless IP cameras, specialized routers, IP video servers, video recorders, video data storage systems, as well as software for video systems. Scalable Cisco video surveillance systems provide fast and convenient access to video and audio information at any time and from almost anywhere in the world.
The Cisco IP camera lineup opens with the Cisco 2500 Day/Night Network Camera, designed for use in IP video surveillance systems at sites of any scale. It is housed in an aluminum case, connects directly to the network, and can be used both indoors and outdoors (in a thermal housing). This IP camera is equipped with a 1/3″ CMOS matrix with progressive scanning and a wide dynamic range and transmits detailed video with natural colors, without the effect of «blurring» or shaking, even in difficult video surveillance conditions.
A movable IR filter switches the Cisco 2500 from color to black and white mode at 0.4 lux illumination on the object, after which the camera continues to generate high-quality video down to 0.04 lux. Cisco 2500 is capable of transmitting MPEG-4 video streams over an IP network with a resolution of up to D1 (720 x 576 pixels) at 25 fps and supports two-way audio. It is equipped with an alarm interface, can be configured via a web browser and is powered via PoE technology or from a 12 V DC adapter. To maximize the quality of the transmitted image, the IP camera supports automatic white balance (AWB), backlight compensation, AGC, etc.
Ability to simultaneously broadcast two video streams
Cisco network cameras are capable of generating and transmitting both single-stream and dual-stream MPEG-4 video over an IP network with different resolutions and frame rates. When transmitting one stream, the IP camera allows you to select a resolution of up to 720 x 576 pixels (D1) at a rate of 25 fps. When transmitting two video streams, the first has a maximum resolution of 704 x 576 pixels (4CIF), and the second has a maximum resolution of 352 x 288 pixels (CIF) at a frequency of both of 20 fps. In this case, the first video stream with a resolution of 4CIF can be used, for example, for recording in a video archive, and the second stream with CIF can be used for broadband video transmission over the network.
Organizing two-way audio communication
In addition to video, cameras in this series are capable of transmitting high-quality audio via an IP channel. Due to the fact that the Cisco 2500 is equipped with a microphone, and also has an input for connecting an external microphone and an output for a speaker, the operator can not only see everything that is happening in the video surveillance zone, but also communicate with people there.
Adjustable three-zone video detector and alarm responses
The Cisco 2500 features a hardware motion detector with three configurable detection areas, as well as 2 alarm inputs for external security sensors and 2 outputs for connecting actuators. If the IP camera detects an event with an alarm status, it can send a message to a specified E-mail address and/or upload individual video files to an FTP server.
Easy access to video via a web browser or Cisco software
Most of the camera configuration and IP video management capabilities are available to the user through a standard web browser. In addition, the open set of system API components supported by the IP camera allows for easy integration into third-party software applications. For a large-scale IP video surveillance system, it is recommended to use Cisco Video Surveillance Manager (CVSM) software with web monitoring, management, recording, storage and search of audio and video information.
Advanced networking capabilities and video security in an IP network
All 2500 series models connect to 10/100BASE-TX Ethernet and support various network protocols, including DHCP, FTP, HTTP, TCP/IP, SNMP, and Cisco Discovery Protocol (CDP) for reliable and secure identification on the network. To provide access to multiple video streams simultaneously for real-time viewing and recording, the IP camera uses Multicast. With the QoS service, the parameters of Cisco 2500 video streams are automatically adjusted to the channel bandwidth. The AES data encryption standard is used to protect the camera and its video from unauthorized access.
