    Design Guide Chapter 1: Video Surveillance Overview Video surveillance has been a key component of many organizations’ safety and security groups for decades. As an application, video surveillance has demonstrated its value and benefits countless times by: ● Providing real-time monitoring of a facility's environment, people, and assets. ●...

  • Page 4: Cameras

    Design Guide Cameras Analog cameras are a key component of a traditional video surveillance solution. They capture images in the environment and convert them to analog video. Each surveillance environment has unique camera and positioning requirements. Installing a camera in the proper environment (with proper lighting, field of view and power) can be one of the most challenging tasks of implementing the solution.
  • Page 5 Design Guide Multi-mode and single-mode are the most common fiber types in use. In multi-mode fiber, light waves are dispersed into numerous rays, called modes, which provide high speeds over medium distances. In single-mode fiber, only one light ray or mode is used to provide a transmission rate that is up to 50 times higher than multi-mode fiber.

  • Page 6: Baluns

    Design Guide Baluns Most existing analog camera deployments have been installed with coaxial cable, but newer installations are introducing twisted pair and fiber optic cables. Because twisted pair is easier to install, a simple solution for new cable deployments is the use of baluns to allow twisted pair cables to transmit video signals, power, and Pan, Tilt, and Zoom (PTZ) data to analog cameras with coaxial connectors.

  • Page 7: Matrix Switches

    Design Guide RS-485 is a variation of the RS-422 standard and is based on a master-slave architecture, in which the master initiates all transactions and the slave only transmits when instructed to do so by the master. RS-485 allows up to 32 devices to communicate at distances up to 500 meters, but the number of devices and distance can be extended using repeaters.
  • Page 8 Design Guide Matrix switches can scale from a small system with a few cameras to an enterprise-class switch that can support thousands of cameras and hundreds of monitors. In a large matrix switch environment, the system may be configured with many components, including: ●...

  • Page 9: Recording

    Design Guide Recording Most video surveillance environments require recording capability either to meet regulatory requirements or to facilitate the investigation of events that have occurred. Many traditional installations that relied on video cassette recorders (VCRs) now record events on hard disks instead of VHS tapes. VCR recording systems are cumbersome and can make timely retrieving of video difficult.

  • Page 10: Chapter 2: Cisco Stream Manager Hybrid Solution

    Design Guide Chapter 2: Cisco Stream Manager Hybrid Solution In a Cisco hybrid solution, a matrix switch seamlessly integrates with a Cisco Video Surveillance digital recording system and provides a staged transition to digital video without changing an interface that is familiar to users. This integration also provides a foundation for migrating to a complete IP infrastructure.

  • Page 15: Step 4: Cisco Stream Manager Modules

    Design Guide Step 4: Cisco Stream Manager Modules Figure 11 shows a complete hybrid system integrating with a matrix switch to provide playback functionality. The system can easily scale to support thousands of cameras and allows operators to use other Stream Manager utilities for added functionality. While the hybrid solution can work without the Cisco Stream Manager Client Viewing Module, this Windows-based software provides a flexible way to view streams from any network location.

  • Page 16: Recorded Viewing Operation

    Design Guide Recorded Viewing Operation When an operator requests a playback feature, the ISP detects the request and responds with the proper playback feature. Figure 12 shows the interaction between the ISP, data converter, and hybrid decoder when an operator who is using Monitor 1 requests to view recorded video from Camera 5 by pressing the Instant Replay button.
  • Page 17 Design Guide Because the hybrid decoder is configured for input port 16 on the matrix switch, ISP_1 instructs the matrix switch to switch video from port 16 to the monitor that is selected (switch video input #16 to monitor #1). The monitor displays the recorded video on Monitor 1. ISP_1 waits for user input and processes features such as fast-forward and rewind.

  • Page 18: Chapter 3: Failover And Recovery

    Design Guide Chapter 3: Failover and Recovery Traditionally, the CCTV industry has considered recorders to be a single point of failure and has avoided recording many video streams on a single device to minimize risk. The Cisco Integrated Services Platform provides recording for many of video cameras and introduces high-availability features that record video streams during failure events.

    Design Guide available encoder ports (8 or 12) on the failover ISP. More than one ISP may be configured as a failover ISP for any number of primary ISPs. ◦ The Cisco Stream Manager Administration and Monitoring with Failover Module. This Windows-based software provides system health information, including information about server and bandwidth use of all Cisco Video Surveillance devices in a network, and central alarm capabilities.
  • Page 20 Design Guide Figure 14. Failover Scenario The following events take place if ISP_2 fails: The Administration and Monitoring with Failover Module sends discovery request messages every five seconds to maintain a list of available Cisco Stream Manager video surveillance devices on the network. If a device does not respond to these discovery requests, the Administration and Monitoring with Failover Module waits three times longer than the refresh interval before logging a failure.

  • Page 21: Single Port Failure

    Design Guide alternate keyboard that is connected to any ISP on the network could retrieve recorded video. During a failure, the Stream Manager Client Viewing Module cannot retrieve recorded video from the failover ISP. Note: In a system that is configured with a 20 second refresh rate, typical recovery times are approximately 75–80 seconds.

  • Page 28 Design Guide Figure 23. Network Settings To specify the Matrix Input port to be used by the hybrid decoder, click Media Settings. In Figure 24, port 16 of the matrix switch is selected as the input port to display recorded video from the hybrid decoder.

  • Page 29: Hybrid Decoder Pools

    Design Guide Hybrid Decoder Pools Hybrid decoder pools ensure that the correct hybrid decoder is used in environments with more than one matrix switch or in environments in which specific hybrid decoders are assigned to a group of keyboards. Figure 25 shows an environment with four CCTV keyboards and monitors but only three hybrid decoders.
  • Page 30 Design Guide Figure 26 shows an example in which the keyboard data converter is connected to the ISP. In this example, pool #1 is configured to ensure that only hybrid decoders in the same pool respond to playback requests from the keyboard that is connected to this ISP. Figure 26.

  • Page 31: Time Synchronization

    Design Guide Time Synchronization Maintaining internal clocks that are synchronized to a reliable time source is critical in a surveillance environment, where video streams need to be retrieved from a specific date and time for review. The matrix switch and the ISPs should be synchronized to display the same date and time.
  • Page 32 Design Guide As shown in Figure 29, ISP_1 is configured as the time master and by specifying the proper serial communications parameters, the matrix switch acts as the time source for ISP_1 and the video surveillance environment. In this case, the matrix switch connectivity is configured for a baud rate of 9600 bps, 8 data bits, no parity, and 1 stop bit.

  • Page 33: Configuring Failover With A Matrix Switch

    Design Guide The ISP also can be configured to receive time from two different NTP sources. To configure NTP time synchronization, choose NTP as the source and specify the NTP servers to provide time to the video surveillance environment, as shown in Figure 31. Figure 31.
  • Page 34 Design Guide Figure 32. Failover Mode In the window for configuring video matrix settings, change the Video Matrix type to match the appropriate system. In Figure 33, Bosch has been selected to support a Bosch matrix switch. Figure 33. Matrix Settings Each port on the failover ISP must be configured to match the port number of the monitor output port from the matrix switch.
  • Page 35 Design Guide The video resolution and frame rates that are specified in this screen are used only during a failure. Because the failover ISP can back up different video ports from different ISPs, this setting does not necessarily match the original setting of the primary ISP. Setting all encoder ports to a high video resolution and frame rate guarantees that video quality is maintained during a failure.

  • Page 36: Configure Video Loss Detection

    Design Guide Figure 35 shows the icon that indicates that ISP_2 has been configured as a failover device. Figure 35. Configuration Module Configure Video Loss Detection The previous section describes how to configure an ISP to detect complete ISP failures. To detect when video is lost from individual ports, each port in the environment must be configured to send an alarm to the Stream Manager Administration and Monitoring Module if video loss is detected.

  • Page 37: Configure The Stream Manager Administration And Monitoring Module

    Design Guide Configure the Stream Manager Administration and Monitoring Module The Stream Manager Administration and Monitoring Modules provide system health information and central alarm management capabilities. Its features include: ● Real-time status, including server use and bandwidth use, of all Cisco Video Surveillance devices in the network.
  • Page 38 Design Guide Figure 38 shows the Failover tab with configuration settings that cause the Administration and Monitoring with Failover Module to detect single port failures or a missing ISP. Figure 38. Failover Settings Note: The Video Loss setting is useful for detecting a failure of the cable that connects to the ISP.
  • Page 39 Design Guide The Administration and Monitoring with Failover Module transfers video streams from a failed ISP to a failover ISP. If only one video channel fails to record, the system switches only that video stream to the failover ISP Figure 40 shows how, after a failure event, available ports on the failover ISP become active and begin recording traffic that was originally destined to a failed ISP.
  • Page 40 Design Guide A simple way to verify that video streams are being recorded to the failover ISP is to select playback keyboard functions, such as instant replay or time/date search, while in failover mode. The failover ISP continues to record until the failed ISP recovers. At that time, the Stream Manager Administration and Monitoring with Failover Module polls the recovered ISP three times before switching back to the primary ISP and returning the failover ISP to standby mode.
