Protecting the learning environment.As criminal threats and societal violence escalate, the need to protect our schools becomes more urgent than ever. Recently, a sad litany of school violence, child abuse, intrusion and burglary has joined the more familiar concerns of behavior problems, graffiti, vandalism and "duty of care" issues. These concerns have made security a rising priority with school boards and administrations across the country. This new priority is clearly reflected in the growing allocations for security in school budgets. In this emerging environment, IP surveillance plays a key role. IP surveillance enables remote monitoring (protocol) remote monitoring - (RMON) A network management protocol that allows network information to be gathered at a single computer. Whereas SNMP gathers network data from a single type of Management Information Base (MIB), RMON 1 defines nine additional MIBs that provide a at multiple sites--a crucial advantage over conventional, Closed Circuit TV. And IP surveillance can help police make prompt and appropriate judgments to resolve emergencies with minimum loss to persons and property. To appreciate the enormous potential of IP Surveillance, compare it with the analog world of Closed Circuit Television (CCTV CCTV abbr. closed-circuit television CCTV closed-circuit television ) and the "analog to digital" approach of connecting analog cameras to Digital Video Recorders (DVRs). Analog CCTV depends on single-purpose cameras, cables, recorders and monitors. For example, the cameras output a video signal over dedicated coaxial cables. The cables connect to dedicated analog video The original video recording method that stores continuous waves of red, green and blue intensities. In analog video, the number of rows is fixed. There are no real columns, and the maximum detail is determined by the frequency response of the analog system. equipment, including multiplexers, videotape recorders (VTRs) and video monitors. Analog CCTV involves a host of limitations: Limited monitoring: Local monitoring only, limited by analog video cable runs and line amplifiers Limited scalability: Systems are typically limited by the input capacity of the analog multiplexer Labor-intensive recording: To maintain an archive, users must eject, shelve shelve v. shelved, shelv·ing, shelves v.tr. 1. To place or arrange on a shelf. 2. and replace videocassettes that are easily lost, stolen or accidentally rerecorded Limited recorded picture quality: VHS (Video Home System) A half-inch, analog videocassette recorder (VCR) format introduced by JVC in 1976 to compete with Sony's Betamax, introduced a year earlier. recording can be a major limiting factor A factor or condition that, either temporarily or permanently, impedes mission accomplishment. Illustrative examples are transportation network deficiencies, lack of in-place facilities, malpositioned forces or materiel, extreme climatic conditions, distance, transit or overflight rights, and the picture quality degrades with every generation of copying. The Analog-to-Digital approach does offer access to surveillance images over the IP network; but it depends on DVRs for both recording and IP access. Sony has made DVRs since 1998 and understands their advantages--as well as the significant limitations that they impose on the Analog-to-Digital approach. Complex cabling: The Analog-to-Digital approach still requires an individual video cable from each camera--a complicated arrangement. Limited scalability: DVRs limit your growth to a typical maximum of 16 camera inputs at a time. An external server with management software may be required to control multiple DVRs or sites. Limited remote monitoring/ control: You cannot access any camera from any client; you can only access cameras indirectly through the DVR (1) (Digital Video Recorder) A device that records video onto a hard disk from one or more ceiling mounted video cameras. Part of a security system, the DVR typically supports 4, 8 or 16 separate camera channels. . Risk of hard disk crashes: The Analog-to-Digital approach exposes your surveillance recordings to loss, compared to the RAID redundancy and tape backup Using magnetic tape for storing duplicate copies of hard disk files. Users can add an internal or external tape drive to their desktop computers for backup purposes, and files are typically copied to the tapes using a backup utility that updates on a periodic schedule. of IP Surveillance. Compared to either of the two earlier approaches, full IP Surveillance is dramatically different. The system takes advantage of cameras with built-in Web servers and Ethernet ports. Instead of generating images as a continuous analog video signal, these cameras generate JPEG JPEG in full Joint Photographic Experts Group Standard computer file format for storing graphic images in a compressed form for general use. JPEG images are compressed using a mathematical algorithm. data files, which can be accessed, monitored, recorded and printed anywhere on the network by any authorized client. The benefits are enormous. Simplicity: All cameras connect to the network via simple, cost-effective Ethernet or wireless Ethernet The standard for wireless networking within a home or office. Also known as a "Wi-Fi" or "802.11" network, wireless Ethernet is the wireless counterpart to regular, wired Ethernet, which is also the standard for local networks. See 802.11 and wireless LAN. . This can leverage the LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. infrastructure you may already have. A single CAT-5 cable can accommodate both camera output files, pan/tilt/ zoom commands and in some cases DC power to the camera. Powerful centralized control 1. In air defense, the control mode whereby a higher echelon makes direct target assignments to fire units. 2. In joint air operations, placing within one commander the responsibility and authority for planning, directing, and coordinating a military operation or group/category of : One server with one software application can run the entire system. Easy upgrade and full scalability: Adding additional cameras is easy; the central server is fully open to future upgrades with faster processors, larger disk drives and more. Full remote monitoring: Any authorized client can have direct access to any camera. You can also access surveillance images through the central server. Robust, redundant storage: Your surveillance images are protected against hard disk drive crashes by RAID redundancy and the option of tape backup storage via SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. connectivity.
