CCTV is used for a number of monitoring and surveillance purposes, but is mainly used for security purposes. CCTV involves the use of an unmanned, remotely mounted video camera system, transmitting live pictures back to a television screen where developments can be monitored and recorded. The quality of CCTV has improved dramatically and the use of CCTV has risen exponentially, with shops and the police the primary consumers of the technology. Modern CCTV cameras are now capable of remote operation and produce high-resolution colour picture quality. CCTV has come so far that it is now capable of recognising individual car number plates and recording them on central databases.
The CCTV cameras were fitted with speakers which allowed staff in control centres to speak directly to people misbehaving on the street, telling them for example to stop fighting or pick up litter. The proliferation of CCTV cameras in public places has led to some unease about the erosion of civil liberties and individual human rights, along with warnings of an Orwellian ‘big brother’ culture. Critics of CCTV say that constant CCTV surveillance of public places is intrusive and a breach of privacy. Following a wide-ranging review of CCTV in England and Wales, the National CCTV Strategy was published in October 2007 and made a number of recommendations. These measures included plans for further regulation of CCTV.
The Protection of Freedoms Bill introduced to Parliament in February 2011 contained provisions for further CCTV regulation and also for the appointment of a Surveillance Camera Commissioner to monitor a code of practice for the operation of CCTV. CameraWatch – – claimed that over 90% of CCTV systems did not comply with the law – i.e. less than 10% were operated and managed legally in accordance with Data Protection legislation. There are only 1.85 million CCTV cameras in the UK, not 4.2 million as commonly claimed, according to research undertaken by the deputy chief constable of Cheshire and ACPO lead on CCTV, Graeme Gerrard. Publicly owned cameras in UK = 33,433Cameras on public transportation = 115,000Total CCTV cameras in UK = 1.85 million.

Again the power generation industry began purchasing these cameras, built into a waterproof housing, to inspect water intake and discharge lines. The interesting part of these early inspections is that no camera was used, these lamp holes were used to lower a candle and in later years the candle was dragged from one manhole to another by floating a thin line, such as a fishing line downstream with the flow and then retrieving it at the downstream manhole. Now the odour associated from the sewer line was not prevalent at the kitchen drain nor at the manhole in the street and more attention was being given to sewer line construction. The electrical image formed by the cells would be scanned line by line by an electron beam, and transmitted to a Cathode Ray Tube or CRT. Hence we are familiar with the term CRT today.
Magnetic coils sprayed the electrons omitted from the electrical image left to right and line by line onto the aperture where they became an electric current. Through years of turmoil, RCA was compelled to pay royalties to Farnsworth, but truly the design started by Farnsworth had been left behind, only the concept of capturing video line by line in an array and the transmission sequence remained. Now the contractor began purchasing cameras from the boiler makers and started using them in the sealing of waste water lines. We were still pulling the units through the line manually after flushing the line and drawing a string to drag our camera through. The typical workday would allow the inspection of a dozen lines but dead end lines or lines which were blocked or collapsed, were impossible to inspect.
Crawlers allow the operator to inspect a line up to a line blockage and then retract and reenter from the end manhole. If used before and after installation of a liner, it will allow the measurement or confirmation of the thickness of an installed liner. Measurement of a line before choosing a lining process ensures that the liner is the correct specification so that costly installation errors due to incorrect selection of materials or process may be eliminated.
