This report provides the findings of a research study reviewing some of the economic and efficiency benefits of the Milton Keynes CCTV system. There are 30 external cameras covering the Milton Keynes city centre and six located in a small town within the city. The monitoring team are based within the Milton Keynes police station and have the equipment to copy tapes on site.
A range of quantitative and qualitative methodologies were used to identify benefits and savings. Case files covering a period of ten months were reviewed to identify cases where CCTV was a key source of evidence, in addition data collected by the CCTV team was analysed. The views of Milton Keynes police officers were obtained using a number of methods, an electronic survey, telephone interviews and a focus group. In addition a range of representatives from a variety of police departments and criminal justice agencies were consulted.
It is clear that CCTV leads to a wide range of economic and efficiency savings to the police. The consultation found that CCTV is a valuable resource which can be used to manage police resources, help investigation and collect intelligence. Some of the main benefits of CCTV to the police are:
The report identified a lot of savings as a result of CCTV, however only some of these could be costed, indeed many could not. However, of those that can be costed the report estimates that in one year the CCTV team may have contributed at least £4,313.49 in actual savings to the police and perhaps up to £7,716.45, these figures are based on a review of 20 files. Again it is important to stress that this is a minimum saving and is far short of the actual. Indeed it is possible to identify additional potential savings of at least £79,510.94 and this may be as much as £287,493.18
In the wider criminal justice system the CCTV team has two clear benefits which can be quantified, obtaining an early guilty plea, which reduces the number of court hearings and costs to the criminal justice agencies, and early intervention, which means that less serious cases are dealt with at court which are likely to incur fewer processing costs. Where CCTV evidence has been used to secure an early guilty plea at least £8,345.18 has been saved for criminal justice agencies in a 12 month period. In addition the impact of early intervention in one year has lead to a potential saving of £1,601,600.
There are numerous benefits derived by the CCTV team to the criminal justice system and beyond which have not been quantified. Two main areas are the detection and reporting of offences and providingintelligence. It also acts as a deterrent and can prevent further incidents occurring through early intervention.
The report has attached a value to the savings achieved by the CCTV team. There are several benefits listed here for which a value was not identified because appropriate data was not available. However, there are some measures that can be introduced to address this gap and apply a value to some of the “unquantifiable” benefits. Improved activity costing by the police to determine the average length of time taken to carry out each step of an investigation would go a long way towards this. Indeed this is likely to be introduced to the force in the next few years. In the meantime better tracking of how CCTV evidence is used and the outcome would also be beneficial.
