In the literature review of this project, I have made a deep study of the published and unpublished work to understand and analyze the different concepts related to the video capturing, surveillance techniques and algorithms, various internet protocols along with the requirements and essential needs for the business professional and firms and the security and safety issues related to it. Several elements and components related with the project were analyzed and studied with the different perspectives to get an idea and the base to predict and get the inferential analysis of the fact and figures to get the final results and conclusions to predict and present the recommendations in the light and support of these analysis.
The reviews and the reports were taken as the secondary source of the data which means that they are not based on the new findings or the experimental researches but just the referential reading material containing the data that has evolved out of the previously done researches and experiments to support for the further research and development. (What is a literature review?)It helped me to build the substantial knowledge base and the acquaintance of various methodologies for the study of the taken research project of IP video surveillance with its application in the today’s business environment. The reviews and the studies were made from the different available resources like journals, books, reports, published or unpublished interviews, doctoral thesis’s, doctoral presentations, newspaper articles, business reports, research papers from the different national and the international conferences and student project reports.
This gave me enough insight of the previous researches done and the further research required and also helped me to know my domain of how I can contribute for the further research. These literature reviews also helped me to build up a base full of the knowledge and the logical aspects for the analysis of the information and the data gathered from the intensive interviews conducted. (What is a literature review?) The study of the few statistical concepts were also done to have a better understanding of the data and also for the removal of any undesired and unrequited error that may have crept in due to the negligence or the ignorance of the interviewee.
To better understand the concepts of the digital and the analog practices and the technology of the CCTV surveillance I gone through the CCTV Surveillance, second edition book available at the Google books. (Kruegle, CCTV surveillance: analog and digital video practices and technology, 2006) The loss and the crime prevention techniques were studied from the “Handbook on the loss prevention and the Crime prevention” by the Lawrence J. Fennely which explained the benefits of implementation of CCTV video surveillance to the institutions. (Fennely, Handbook of loss prevention and crime prevention, 2003) The researchers conducted by the IMS showed that the IP video surveillance is the fastest growing field of research in the physical and the remote security. (The business to business trade publication for information and physical Security profe, 2009)
The increasing sophistication of the video analyst software and its integration with the other sensors were understood from the book “Protecting Privacy in Video Surveillance” by Andrew Senior. (Senior, 2009) The changes in the technologies, advantages and disadvantages of the IP video surveillance system, etc were studied from the different sources like an article by Lucy P.Roberts. (How IP-based video surveillance works) “There is a growing need for information to support business intelligence application. Business intelligence information such as counting of people going in or out of the store, determining customer shopping habbits, information on the store occupancy information, and the others can be gathered using the video analytics.” (Branislav, Embedded Computer Vision, 2009) Besides, several research papers like “Towards developing Secure Video Surveillance over IP”, “Design and implementation of an IP-based Intelligent Video Surveillance System” were also studied.
The IP video surveillance is one of the most promising technologies of the future that is designed to work on the Internet Protocols and allows the users to get the view of the distant images digitized over the local area or even the wide area network. The devices like high resolution video camera, CCD, etc takes the scene in front of it, converts it to the corresponding digital signal send it over the network, where it is transmitted to the computers, servers, etc to finally reach the destination. The server has the responsibility to manage all these information. These digital images are managed, recorded, displayed, and retransmitted to any part of the world using the various tools and techniques with the various software, hardware and algorithms. The software packages that is involved with the use of the video surveillance can be modified to serve for the various purposes like analyzing the data, selecting some of the features and the objects to watch for, hosting various functions, analyzing the environment, thus building it into the a powerful customizable tool for security and various other purposes. (Video Surveillance Technology)
The IP-based digital video surveillance makes the use of CCD cameras which are the charged coupled devices, and use the digital signal processing tools and algorithms that sends the packetized or the buffered video streams over the LAN or WAN using the standard TCP/IP communication. (Video Surveillance Technology) To make the better utilization of the bandwidth, the transmission is done through a Cat 5 cable rather than the coax cable network. The IP video surveillance can also provide various intelligent data mining and information retrieval techniques to smartly analyze and extract the logical information from the video being processed.
The tools and techniques like the data encryption and some others can be used to protect the transmitted data against the image processing in order to do away with the security issues if they are essential for the transmission of the videos to the remote locations. The technologies of the IP video surveillance is getting more and more advanced and in the recent developments the companies like D-Link and Linksys have developed such efficient digital cameras that have actually integrated the built-in web servers and no external device or computers are required to operate them with the signals being transmitted directly to the required remote locations for the storage and play-back purposes. (How IP-based video surveillance works)
HOW DOES THE IP VIDEO SURVEILLANCE WORKS
Earlier the technology that was used for the video surveillance was the analog technology. The process was quite simple with the use of the closed circuit televisions (CCTV) and the recording on the tapes. The recording used to be fine, where the images and the videos were used to get recorded on the storage devices and played back later on for the surveillance purposes but the problem was that it didn’t broadcast the actual live information, so although it used to provide the essential information but was obviously impractical for monitoring the remote locations, etc. The quality of the picture was also not very good and also the human reliability was required as someone has to interfere with the system time to time in order to change the tapes regularly, etc. (Networks, 2010) In the simple terms, it provided the video after the happening of the fact and not instantly.
With the revolution in the internet technologies in the 1990’s and the increasing presence and the demand on the Local Area Network revolutionized the field of the video surveillance too. Now, the traditional analog cameras were able to be replaced by the digital ones and the Charged Coupled Devices (CCD) which came into the existence and gradually became affordable to most of the people. (Networks, 2010) With this revolution in the field, it provided the surveillance to do the important things like going live over the internet or a closed network for the purpose of surveillance, provide the better picture quality, clearer in view which can be easily manipulated. With the digitized images, it became much easier to zoom the images, track the particular scenes and enhance the feature as the user desires which has a large number of applications in law enforcement, defense purpose, research and development processes. (Video Surveillance)
ADVANTAGES OF IP VIDEO SURVEILLANCE
There are a number of advantages of the IP video surveillance for the home, business, defense, and research related purposes. Some of them are listed below (IP Camera Advantage and Disadvantage):
The IP video surveillance can be very efficient in terms of its flexibility as the IP cameras can be highly mobile in the terms that it can be moved anywhere in the network having the IP standard. This mobility and the flexibility can be of very high level in case of the wireless networks. (IP Camera Advantage and Disadvantage)
The cameras used in the surveillance, the IP cameras can be provided with the modifications to implement the distributed intelligence. This can be done by the various ways like adding the video analytics right on the cameras allowing it to get the scalability in the analytic solutions. (Benifits of network video Surveillance)
The IP video surveillance also allows the two-way audio/video transmission through a single network cable which can allow the users to communicate with what they are seeing. (IP Camera Advantage and Disadvantage)
With the development of the type of cameras in this field, various high range cameras with the high resolution which can provide the multi-megapixel resolution of the image and the HDTV image quality as high as 30 frames per second on a normal network.
Transmission of the digital commands for the features like pan, tilt and zoom (PTZ) via a single network cable is also possible. (Benifits of network video Surveillance)
The transmission of the videos can be done through the various encryption and authentication methods such as WPA, WPA2, WEP, TKIP, AES, etc. (IP Camera Advantage and Disadvantage)
Another advantage of this technology is that it is highly remote accessible i.e. the live videos captured from one place can be viewed from anywhere in the world, any computer, any internet enabled device, also from the mobile smart phones, etc even they can be correspondingly viewed from a number of places at the same time. (Benifits of network video Surveillance)
For the large systems like those that have more than 25-30 cameras, the IP video surveillance system becomes highly cost effective.
The IP video surveillance can also be managed to function over the wireless networks which requires only the initial configuration through the routers after which they are ready to be used in the wireless network. This technique is of the extreme importance for their use in the navigation purposes in the defense forces. (Wireless Internet Video Cameras)
The cameras used in the surveillance i.e. the IP cameras mostly do not require the additional power supply and can be operated using the PoE i.e. Power over Ethernet using the PoE protocol which derives the power from the Ethernet cable for the cameras to operate. (Power over Ethernet (PoE))
DISADVANTAGES OF IP VIDEO SURVEILLANCE
With the number of advantages of using the IP Video surveillance, there are also few disadvantages related to its use. Some of them are listed below (IP Camera Advantage and Disadvantage):
Comparatively high cost related with the surveillance due to higher initial cost related with the camera and its installation except for the cases when the cheap and less expensive webcams are used. (IP Camera Advantage and Disadvantage)
If the system is transmitting the videos over the public Internet rather than a private LAN whether it is the CCTV or the DVR system, the system becomes quite opened to the hacking and cracking via the internet. Attackers can attack to the transmission stealing the various personnel, business or defense information which can be very harmful for the users. (IP versus analog cameras)
The bandwidth required for the system is very high. A typical CCTV camera system of the resolution of 640X480 pixels and 10 frames per second in the MJPEG mode requires the bandwidth as at least 3 MB/S which is quite high for a normal user. (IP versus analog cameras)
The installation procedures of the camera systems are considerably complicated and require the professional technical assistance. (IP Camera Advantage and Disadvantage)
COMPARISON WITH THE TRADITIONAL VIDEO SURVEILLANCE TECHNIQUES
As described above earlier the analog or CCTV/ DVR system was used for the purpose of the video surveillance instead in comparison to the topic of our discussion which is IP based video surveillance. The comparison is summarized in the following table:
IP Video Surveillance
Analog or CCTV/DVR Video Surveillance
The IP based video surveillance means the instant transmission of the images anytime anywhere and in the world.
The live transmission of the obtained video is neither possible nor practical.
The quality of the recorded video does not decreases with the number of replays or repetitions.
The quality of the storage gets poorer an poorer with the repetitions.
The IP standard can be used to control a number of cameras at the same time from one remote location
The recording on IP basis can be highly compressible and can be transported in the various ranges of formats, size and quality.
Storage of the analog videos is generally much more bulky than the digitized ones.
Digital picture quality is generally better to that of the analog ones.
The image quality is inferior to that which is obtained from the digital ones.
Encryption can be done for security purposes for the digital images.
There are almost no encryption techniques available for the analog videos.
The updating in the requirements can be done very easy and inexpensively by having the updates and add ons in the software package or Internet networking.
The updating just means the updating in the hardware.
The frame rates are adjustable.
Frame rate can adjusted only through the hardware not through any algorithm.
The number of cameras can be easily added, removed or modified with very ease.
The number of cameras can be added or deleted only in the set of 16 as in the case of DVRs.
Sharing can also be done on the wireless networks like Bluetooth, ZigBee, Wifi, etc
Only the physical transport of the tapes is possible.
Standard IP video compression techniques can also be utilized.
These techniques are not applicable here.
