Can CCTV reduce crime?

The effectiveness of CCTV are announced regularly. police in across the country recently claimed a drop in crime following the installation of a closed circuit TV system in the country. Not only are people delighted because they are no longer afraid to go out shopping, say local police, but even criminals welcome the chance to prove their innocence by calling on evidence from the security cameras. Crime in car parks has dropped by fifty per cent where camera exist. People say they feel safer. Indeed they should. Assaults and other violent crimes appear also to have been decimated in the center of town.

The logic, and the statistics, are superficially impressive, but some analysts are not convinced. In a report on the impact of CCTV,

The crime reduction claims being made by CCTV proponents are not convincing. Three recent criminological reports have discredited the conventional wisdom about the cameras effectiveness. In a report to the Scottish Office on the impact of CCTV.

The crime statistics rarely, if ever, reflect the hypothesis that CCTV merely displaces criminal activity to areas outside the range of the cameras. One of the features of current surveillance practice is that the cameras are often installed in high-rent commercial areas. Crime may be merely pushed from high value commercial areas into low rent residential areas. Councils often find that it is impossible to resist demands for such systems. There is an additional element of displacement that should be of particularly concern to all communities. Since the growth of CCTV as the primary means of crime prevention, more traditional, community based measures have been discarded.

A report on CCTV in Airdre was unable to rule out displacement as a factor. 5 while various studies in other countries indicate that burglars and other criminals will travel long distances to commit crimes. 6 Discussing the justification for establishing a surveillance system of 16 cameras in Manchester,

In other words, crime may be merely pushed from high value commercial areas into low rent residential areas. One of the features of current surveillance practice is that the cameras are often installed in high-rent commercial areas. Councils often find that it is impossible to resist demands for such systems. The trend is fueled in part by the insurance industry, which in some towns is offering a thirty per cent reduction in premiums to local retailers who pay a contribution to a CCTV levy system. A nationwide insurance discount scheme is currently being negotiated, and should be in place by 2007.

Some police also concede that CCTV displaces crime. Richard Thomas, Acting Deputy Chief Constable for Gwent, recently told the BBC’s Andrew Neil that he believed CCTV pushed some crime beyond the range of the cameras. 8 And in his interview with 20/20, Leslie Sharp said “Certainly the crime goes somewhere. I don’t believe that just because you’ve got cameras in a city center that everyone says ‘Oh well, we’re going to give up crime and get a job”.

The cameras are also creating a vastly increased rate of conviction after crimes are detected. Virtually everyone caught committing an offense on camera pleads guilty nowadays. Once people know they have been videotaped, they admit the offense immediately. Such is also the case in Newcastle, where the installation in 1992 of a 16 camera system has resulted in a 100 per cent incidence of guilty pleas. 9 Police are delighted at the time and money they are saving from long and expensive trials. Some legal experts are a little more wary of the implications of these results, arguing that – like DNA evidence – juries can be seduced and defendants intimidated in equal proportions by evidence that might not normally stand up to scrutiny. Indeed some districts are now reporting that people are surrendering after the mere mention in newspaper reports that their alleged activities had been captured on CCTV. 10

The future lies within Security Network IP camera

The future of Security Camera and Surveillance System lies in the Network IP technology. The video Camera being used over such networks opens up a whole range of Security video CCTV applications that can be used by the network users!
IP is a protocol (Internet Protocol) receives packets from the data link layer (Ethernet) and sends them to the correct address. If more than one possible route is available for the data to travel, the network layer figures out the best route to go by. The core of IP technology uses Internet addresses. The IP address is a series of numbers separated by full-stops (e.g. and identifies one network interface on a host. Every device on a network needs a unique IP address.


A digital video surveillance system is an appliance that acts as a network device and it has its unique IP address and can communicate like any other network device. This device has embedded image capture capabilities which allow video images or extracted information to be captured by the network security camera and be compressed, stored or transmitted over communication networks or digital data link. This security IP Camera can be used for any type of monitoring, either for business or personal use.
IP camera can compress data in different format, like MPEG, MPEG4, and H264. Additionally IP camera technology offers the ability to use intelligent image analysis functions and different types of networking protocol support. IP surveillance hardware and software partners offer complete solutions for a diversified range of products.
IP video surveillance solutions are primarily based on the high performance Digital Media processors which have on chip video ports for easy connection to video surveillance devices. The Security camera IP devices are capable of handling both video and audio encode/decode for IP based video surveillance applications. Cost competitive video compression/decompression algorithms are available through JPEG, MPEG2, MPEG4, H.264, and more. Audio compression/decompression algorithms are also available.

Network IP cameras are flexible, powerful, and they are the key to providing you with wide ranging surveillance solutions in system design, applications and solutions of CCTV or Security camera, Security DVR need. Network IP cameras are connected to the network like any other network device and with their built-in web server allows you to connect and watch live video stream directly from a computer with the use of a standard Web browser on a local area network or from any location in the world via the Internet.

Wide rang network IP camera products:

You can find fixed network IP cameras for both indoor and outdoor applications, as well as pan/tilt/zoom Cameras and network dome cameras that enable remote control of pan, tilt and zoom functions over IP networks. DVRMaster also offers video servers that allow you to connect CCTV Camera, analog security camera to IP Network surveillance solutions which help analog CCTV systems take advantage of the benefits of a digital, networked world. Surveillance Video management software and accessories such as network IP camera housings and devices that bridge between analog and digital, are also available.

Power over Ethernet for IP cameras: With a network IP camera or video solution, you have the option of using the same cat5 Ethernet cable both for data/video communications as well as to power the IP Camera. This feature installation of IP camera products much easier and cheaper since you need to run only one wire per camera and you can connect all the security IP camera to redundant power source that make the camera able to operate even when there is a power failure.
