Since the initial emergence of CCTV system more than 35 years ago this decade has seen by far the most remarkable stages of advancement and development of these amazing security systems. The rapid advancements of security technology in general have contributed to smaller and more efficient security cameras. Though important, the development that holds the most significance is in how the actual surveillance footage is captured, stored, and managed.

Traditional security software technology was very primitive from the sense that that it was helpful only after the occurrence of the unusually, sometimes dangerous, incident. Clearly, nothing major can be done after the incident has already taken place. On the other hand, intelligent video software technology will enable the security industry of providing a proactive technology that fill fight off criminal behavior as soon as it is spotted by detecting questionable actions when and even before they take place.

Intelligence is incorporated to video as it is captured and evaluated by behavior detection software, which is why it is called intelligent video. Converging intelligent video software with CCTV has resulted in greater situational awareness of threatening situations as they unfold as well as the generation of more accurate alerts and alarms. Having this terrific technology enables surveillance personnel of better managing their human assets, as well as have the peace of mind of realizing that their entire CCTV network is entirely protected and secured. Not to mention attain significant savings in surveillance expenses.

The Transportation Security Administration is presently testing the intelligent video software by setting them up in various transportation facilities and departments in an attempt to immediately enhance the security level of transportation and government institutions.

Adding on, this security software has an essential role when it comes to protecting vital and fundamental infrastructure properties, such as power plants, banks, utilities and information centers. Intelligent video will rapidly evolve into a mainstream technology as more and more individuals realize the capabilities and priceless value of software-equipped CCTV.

The Implementation of Action Detection

A major advantage of intelligent video is that it abolishes the necessity for constant human supervision of the surveillance footage for potential occurrences. A security personnel is simply not able to carry out this complex task duty, this is due to the large quantity of cameras that he has to monitors, with each camera carrying out its own rotation cycle, not to mention the various other duties that and assignments that her or she is already responsible of.

Intelligent video systems relieve security guards from having to constantly monitors the cameras and allow them to focus on other essential requirements of their job. As soon as a preprogrammed behavior is sensed, the security cameras instantaneously start to record, alarm messages and notifications are also send to the authorized individuals. If for any reason the security officer is not able to address the emergency during a set time interval the security alert is forwarded to a second guard.

The surveillance software manages an all-inclusive, enterprise-wide reaction. This is particularly significant when quite a few diverse groups of responders are required to intervene in a specific incident. Not to mention that intelligent video systems also enable security staff to playback individual actions to any particular incident, examine the occasion’s data and response times, as well as apply enhancements when required.

The capabilities of some of the higher end security detection software in today’s surveillance market are simply amazing. Not only can they recognize a human being, but they can also differentiate him from a nonliving structure as well as precisely calculate the number of individuals in its view range. CCTV cameras utilize video algorithms in recognizing a wide range of human behaviors and actions such as loitering or penetrating a secure area, as well as particular style or dimensions of vehicles, luggage, parcel or packages.

The Necessity of Industrial Standards

It is obvious that intelligent video systems require a dependable, well known, and preapproved system to gauge the precision, efficiency, and accuracy of the software. This will not only drive companies to constantly improve their products but it will also provide the consumers with a way to judge between the many products displayed in the security market just like any other security device.

These preapproved industry standards will have to determine first what accuracy and precision mean in regards to the intelligent video software. Adding on, a security device might be able to carry out its tasks in ideal conditions, such as tracking an objects movement as it moves in a straight line against a single colored background. However that alone does not guarantee that the software will be able to perform the same job with the same level of accuracy in a multicolored environment or with several objects all moving at the same time.

The topic of industrial standards is truly a significant one that every security software manufacturer should pay close attention to. May industrial bodies and agencies such as TSA and the National Safe Skies Alliance are actively involved in testing an assortment of surveillance software in an attempt to create an accuracy benchmark test for the surveillance industry.

TSA has recently publicized criteria for biometric equipment as well as provided a set of guidelines to install this vital technology in airports and other major transportation facilities. Some of the benchmark test categories should include but are not limited to extent of noticeable behaviors, accuracy, settings under which the system must function to be truly effective and the ability to converge with other devices. It must also list the number of cameras it can maintain.

These fundamental standards, as well as many others that describe the ability to produce alerts and administer the necessary responses, will assist consumers make a well educated choice when it comes time to finally make the right purchase that will address their security needs.

The first step to use behavior detection technology is to recognize the exact trouble or threat at the specific site. This is followed by selecting the suitable algorithm that corresponds to that activity’s category. As one can guess, algorithms libraries are being created, expanded, and fine tuned constantly to serve highly specialized security requirements of the society.

The creation of this intelligent surveillance software has discharged the security personnel from the terrible deed of having to watch their security monitors for hours with no real activity taking place. On the other hand it has allowed them to only respond to incidents that need immediate and urgent attention.

Significance of Pattern Detection

The underlying layout for intelligent video is already present; the cabling, cameras and recording equipment are already set up. The hurdle is administering these various security cameras and what they display.

In order to guarantee the maximum productivity and efficiency possible, the security software must be set up to communicate with all the cameras and visual surveillance equipment in a property. Doing so will create an active detection network that is far more superior to a standalone security cameras. Not only does pattern detection precise in identifying suspicious incidents in the time of their occurrence but it can forecast danger well before disaster takes place

Activities that are usually marked as suspicious behavior would include individuals who constantly take photos of a particular location in the facility or the property in general, or others that visit the facility and case it a lot for no apparent reason. These types of activities and many other could be could be the preliminary steps leading to an attack of some sort. As soon as this type of activity is detected by the surveillance cameras the authorities are notified which enables them to immediately launch an investigation to address the issue in the early stages of its development before it is too late.

The terrific ability to detect patterns is a powerful tool that the security software possesses. To understand just how beneficial and potent this feature truly is let us imagine a simple scenario. A security personnel is guarding the entrance to an airport or any other building. A vehicle is parked at a far distance near the entrance but it is still visible to the guard. The guard can not tell just by looking if this is a suspicious car, a visitor observing the airplanes as they take off, or a coworker taking a break in his car further more. The car might happen to be positioned at a location not visible by the guard. Furthermore the guard might not be on duty if the vehicle comes on the guard’s off day. The security guard’s ability of observation and memory is also a factor that should be taken into consideration. Not to mention that this same vehicle can appear in other airports or properties and no one will be able to relate between the two appearances.

However with a security software connecting the dots is much more feasible. A security software can make the security guards aware of these suspicious patters and will allow them to conduct further examinations to discover the true cause of an incident and whether or not it is linked to a bigger scheme. By providing the guards with the summary of suspicious activity for the day it relives them from having to waste their energy on observing a security monitors for an entire day. It will allow them to save their energy to investigate actual suspicious activities and real threats.

Significance of numerous Inputs

It is obviously clear that a successful monitorsing experience is associated with getting and managing the maximum existing number of inputs. Among the security technologies that should be integrated with the security software are access control systems. For instance, the security system may detect that someone’s access card was denied in two entry gates. Soon after, a tailgate event is reported. The security guards can get a complete perception of the incident if they simply review the summary provided by their security software.

Increasing the number of security devices and checkpoints that are connected with the security software will untimely guarantee a more detailed layout of the events in a suspicious incident. Security personnel can immediately take action and begin investigating the situation as soon as they realize any type of suspicious pattern registered by the surveillance software.

Although visual media footage is considered the main aspect for pattern recognition it is by no means the only element of helpful feedback. Standalone detectors such as biometrics, smoke detectors, and card scanners can also be incorporated into the construction of video to present supporting material or clarification of an incident. For instance a guard is able to find the identity of the person whose card was denied by viewing the security video at the exact time the access control system denied the entry.

As we can clearly see, incorporating various and numerous inputs in a single security software will fill the many gaps often missed by a single security device’s normal restrictions. It will also provide a more complete story for security personnel to examine.

Future Plans

Security capabilities are being extended in ways that were not possible a few years ago, due to the rapid advancements in intelligent video software which brought alert management technology and behavior recognition to CCTV systems.

This has enabled security personnel to conduct their jobs more efficiently, adding on security resources can also be deployed in more cost-effective manner.

There will certainly be an impressive forward leap in security as the quality of optics continues to improve, and CCTV systems begin to incorporate high-definition cameras, as well as thermal and infrared devices. Other improvements are expected to incorporate the installment of software intelligence at the surveillance camera itself, so that footage files are conveyed over high-bandwidth networks only when they hold essential data.

The continuous establishment of standards and evolution of intelligent video technologies, security personnel will have the ability to forecast and respond to incidents even more rapidly, efficiently and effectively.
