With better resolution, one camera can cover a wider area, or digitally zoom for fine detail. 2. Standard IT infrastructure.

Organisations may find the move from ADVANCINGVIDEO algorithmic and rules-based systems to a learning technology a helpful next step to improve a video surveillance system. The key to successful surveillance is learning SURVEILLANCE IN normal behaviors, so that suspicious behavior can be detected to help predict, and prevent, future threats. By filtering out everyday activity, learning technology can help focus security personnel on SECURITY unusual activities, which helps to raise organisational awareness and decrease response time to potential threats. Scalability is key to success A video analytics technology capable of learning relies on computing power, which requires organisations to ensure Video surveillance was once the exclusive province of that all elements of the system have the potential to scale to meet the needs of physical security; operators looked at multiple video even larger video surveillance operations. screens, each displaying the field of view of a single video Scalability is crucial; the sheer amount of video surveillance now being deployed camera, to monitor for security incidents.

  5. 5. Digitised video and security Today, a full video infrastructure includes cameras, viewing stations, video storage and recall, video analytics, and analytic processing. It may include remote monitoring or publishing video to remote locations, and it may require encryption of the video stream. Video isn’t just video any more. Video is data; data that enters the realm of IT. Like any other type of data, digitised video must be analysed, shared, transferred, archived, searched, and more. This makes it even more crucial for video surveillance systems to comply with open standards, since they are essential to getting the most value from the data. With video surveillance as a data technology, security personnel will have to handle video data just like any other data. Video data will have to be integrated into the data security infrastructure, electronically signed to prove it has not been tampered with, tied into the IT infrastructure’s existing permission and security systems so security can control who views it, and encoded for transmission. Incident manage -- when the video surveillance system sends an alert, security personnel will need to enter comments about what actions they took to mitigate a risk or handle a security event and provide audit trails.

Advanced video analytics can be configured to look for a person loitering in a parking lot or crossing over a fence, and only record and stream video when that happens. The technology can also alert personnel to loss of video or tampering. Furthermore, it can create an index of events and store them in a database for future mining. Video analytics software is best integrated with the VMS at each site. It intercepts the video feed from all cameras and then analyses live video in real time with minimal latency. Events are stored in a database and posted to one or more alert consoles that have subscribed to those events. Video corresponding to those events is also streamed to these consoles. In effect, video analytics serves as a traffic cop, interacting closely with the VMS. In most cases, an analytics-enabled VMS can be deployed on existing infrastructure with minimal changes. Video analytics provides a win-win situation, by enabling security personnel to prevent crime instead of investigating it after the incident, and by allowing IT staff to provide a compelling solution that is cost-effective to deploy and maintain. It greatly reduces the operational expense of a distributed video surveillance solution while allowing centralised administration and monitoring. This mature technology is transforming the way enterprises plan and deploy IP video surveillance systems. 7
  8. 8. CIOSURVIVALGUIDE FEATURE HOW TO MANAGE SURVEILLANCE VIDEO Video management software (VMS) allows you to record and view live video from multiple surveillance cameras--either IP-based or analogueue cameras with an encoder--monitor alarms, control cameras and retrieve recordings from an archive. B ecause they are IP-based, VMS systems are more expandable and flexible than DVR-based systems, and employees can control the software from anywhere on the network. Surveillance and security teams can use the software for live monitoring, as well as investigative and forensic purposes, using archived footage. Users have three form factors from which to choose for managing IP video: software-only, hardware/software appliances (sometimes referred to as network video recorders, or NVRs) or a hybrid DVR, which is a DVR with additional software to manage IP equipment. Because of the economic downturn, the VMS market will see slower growth in 2009 than in previous years, with a forecast of 29 percent versus more than 40 percent, according to IMS Research. Evaluation criteria for video management VMS systems range from the basic to the sophisticated, with major differences including reliability features and number of cameras and locations supported. Here is a sampling of features to consider: Specific options for different verticals, including retail, banking, transportation, etc.; Video analytics, such as license-plate or facial recognition; Integration with third-party systems, such as access control, building automation, alarm management, video analytics and more; Motion detection;8

You can to upgrade networks or too difficult to because of their moving parts.10
  11. 11. standards, such as in the areas of security and video compression, Gartner recommends. Also look for open application programming interfaces and multiple supported software applications. Scalability: Companies with large installations will want the equipment to be compatible with tools that locate, update and monitor the status of the devices and their IP addresses. Service/support: Make sure the vendor or reseller is able to send replacement parts quickly and can readily offer engineering support. Many network camera manufacturers sell indirectly through channel partners, which is common in the IT industry but not in the security industry. This takes some getting used to among traditional security personnel. DOS and DON’TS DON’T let cost be your guiding light.

In many solution of choice due to the latest H.264 cases, it also is more cost-effective than a conventional video surveillance system with compression technology and declining prices for IP analog cameras and digital video recorders. Using IP cameras, video management cameras.

There is no single, IP video solution or ideal configuration. For example, if you have a distributed organisation with hundreds of smaller sites spanning a large geographic area, coaxial cable and networked video recorders might make more sense for recording video at relatively low frame rates. An all-IP configuration, however, may be the most cost-effective solution if you need very high resolution video or the intelligence available from advanced video analytic applications. Other IP video benefits include the ability to access remote locations via your LAN or WAN and centralise security monitoring instead of stationing guards at each site. Furthermore, with VMS software running on industry-standard servers, an all-IP system can be managed easily by your existing IT staff. An IP video environment also lets you leverage video for uses other than security. An IP video system can be used to support marketing activities and operational management. For example,video security is a no-brainer. However,bringing video security onto your IPnetwork is far from an all-or-nothingproposition. Using advanced video Other IP video benefits include the ability tosecurity technology, you can evolve access remote locations via your LAN or WANtoward an all-IP configuration at a pacethat makes sense for your environment. and centralise security monitoring instead Take, for example, a universitycampus with several buildings under of stationing guards at each site.construction.

Using ONVIF enabled Sony products unlocks freedom of customer choice and delivers the exciting opportunities available from integrating Sony’s truly flexible and scalable network video solutions What will be the impact of new technologies such as improved facial analysis and analytics? Facial recognition and image analytics are still in their infancy in terms of their accuracy. However, it is very clear that these technologies can and will play an increasingly critical role in the security industry. As mentioned previously, we believe the higher resolutions enabled by HD will be a driver to the successful adoption of these exciting technologies. What roles will different types of wireless technology play in this market? Wireless technology plays a small but important part of the security industry. Sony is proud to say that almost all of our cameras come equipped with a wireless card slot. Sony has unveiled a new range of high definition pan tilt zoom (PTZ) security cameras. Does HD technology suit the security industry? Can you transmit HDTV signals over conventional closed- circuit TV media? The Video Security industry is highly reliant on the very best technology to provide clear images. These could be used for identification, recognition or even prosecution of criminals. This alone makes HD a perfect solution for security applications. However, it is equally important to ensure that the network bandwidth is managed efficiently. With this in mind, Sony has been asystem integrators alike.
