201 conditions, and similar to the police for IT Solutions in marketing advertising, there is a lack of
objective danger. Overall, by serving police officers are engaged in research are one-sided cited statistics  on  police  authorities  information  as  the  basis  for  not  considering  the  effect  of  other,
variables, the only similar nature of police operations reports, easily generate Dangjuzhemi blind spot,  should  solicit  legal,  academic  and  civil  society,  such  as  views,  whether  public  opinion
research conducted, not missing the party objectivity. 2.3 Privacy Issues and Social Phenomena
Recent evidence suggests that it may encourage increased reporting of crimes to the police and increased recording of crimes by the police. CCTV may also cause crime to be displaced to other
locations, times, or victims, and also raises concerns over threats to privacy and civil liberties Welsh and Farrington 2009. From the erection considering factor Strategic Management angle
to measure surveillance recording system, the researchers summarized their field visits to nine research  areas    townships    experience  and  interviews,  analyzing  set  surveillance  recording
system  should  pay  attention  to  environmental  design  social  determinants  and  psychological decision.  considerations  and  other  -oriented,  and  for  the  hazardous  journey  of  these  regions
degrees according to their subjective judgments to score, and then to SWOT analysis to do cross- analysis  to  assess  the  installation  of  the  monitor  strategy,  although  this  effectiveness  of  the
method has not yet been assessed, but this study presents an interesting strategic point of view, available for police authorities refer to the use of Li Yong Qing, Xu Peng and Ai Peng, 2006.
For the police investigation of the case method of conducting discussions, propose target track concept, that is, for criminal cases related objects or intelligence, according to their chronological
order to establish directional links, the point -rays consisting of pattern generation, that is called the target trajectory. Its so-called object or intelligence means the objects relevant to the case or
information on investigative practices such as: crime sites, crime locations, through joint records, communications  surveillance,  phone  number,  transport,  Internet  addresses,  GPS  information,
invoices, credit cards, debit cards and can be used as a traffic ticket establish target track objects. This paper enumerates seven use target trajectory concepts and detection of criminal cases real
examples, itemized description of its application scenarios in the criminal investigation, and one that is in Taichung poison bull incident as an example, the Monitoring the recorded data as the its
so-called object or intelligence, one of the promising, describes how the police use the recorded data to track criminals, thereby cracking criminal cases Zhanming Hua, Li article, 2006. This
part  of  the  literature  only  major  cases  for  the  study,  but  the  police  when  investigating  major cases, often invested a large amount of manpower and resources, and are manually each filter
huge  recording  data,  if  only  to  observe  the  police  of  such  indigenous  steelmaking  style investigative methods, the application can almost predict will form a conclusion ─ surveillance
recording system is to place all of the prison near the crime record all screen filter. However, the practice in the use of surveillance recording system to assist cracked the case but not limited to
major criminal cases, and because of the limited police powers and Benefit Evaluation and other factors, more investigation is not possible in any  case  are individually recorded data  filtering.
Therefore,  the  present  study  was  to  explore  the  application  of  this  criminal  investigation techniques and technology, to understand how the police can use this tool in these small cases.
Routine activity theory of criminology that is revealed when a motivated offender encounters a suitable subject matter, if the site has a strong presence of the supervisor, then the crime will not
happen,  but  for  many  people  in  terms  of  crime,  surveillance  is  indeed  a  powerful  supervisor, especially  for  property  crimes,  but  also  play  a  preventive  or  deterrent  effect  ;  for  prevention
202 through environmental design to achieve the purpose of the crime, must respect the software is to
enhance  peoples  awareness  of  both  hard  and  soft,  and  hardware  aspect  is  committed  to improving  the  spatial  form,  where  the  installation  of  CCTV,  the  more  important  indicators.
CCTV  recorded  by  the  perpetrators  face  with  the  criminal  process,  so  that  the  perpetrators escape  detection,  but  as  the  irrefutable  evidence  of  a  crime,  the  real  weapon  of  Criminal
Investigation.
3. Research Methodology
The research uses literature review as the base for induction and it is to introduce the general conditions some countries using surveillance camera systems by comparative research method.
According  to  the  five  approaches,  the  community  surveillance  condition,  circumstances  crime prevention, relaxing index on the installing surveillance camera systems, the self-evaluation of
interaction between police officers and people, the evaluation of privacy on surveillance camera systems through the questionnaires on 274 village heads and 65 chiefs of police stations to be
quantified analysis. In the light of reporters, councilors, detectives, referring their opinions on the efficiency  of  surveillance  camera  systems  to  the  crime  prevention,  this  study  uses  the  semi-
constructive  interview  method  to  deduce  the  domestic  experimental  data.  On  the  other  hand, induct  the  pros  and  cons  from  domestic  and  abroad  scholars  viewing  on  the  installment  of
surveillance camera systems in public areas, and use the cross-examination discussions to make clear on police facing the problematic nature by using in practice this technology. Due to the
above-mentioned retrospectives, discussions, analysis, and inductions, this study developed the theoretical base for this research and conduct as the guidelines of interviews and cases analysis
to design research outline and develop research questions. This study adapted the interview data to understand the real applying condition on recently the surveillance camera systems to crime
prevention  and  by  using  cases  analysis  method,  analyze  minutely  the  links  on  elaborating functions of surveillance camera systems at the time of investigating crimes and further bring the
findings and suggestions from this research. Finally, this study adapted the quantified analysis and  characteristic  study  to  find  out  the  future  embarrassments  and  limitations  on  surveillance
camera  systems  on  crime  investigations.  Furthermore,  we  introduce  the  practical  units  some feasible  plans  and  improving  guide  lines  and  the  purposes  are  to  enhance  the  efficiency  of
surveillance camera systems and in the meanwhile, to increase the people’s satisfaction of public security and a sense of security.
4. Discussion
Technological skills are mainly to discuss the levels of the relative skills of surveillance cameras and focus on the applying for new technology rather than provide any ideas about the installment
of surveillance camera systems in public areas; on the other hand, agree that the installment of surveillance camera systems is good for the public security. Thus, they  conclude a hypothesis
one:  the  installment  of  surveillance  camera  systems  to  the  individuals’  recognition  has  the positive influence. The relative documentaries on issue of human rights center on speaking about
the  surveillance  camera  systems  infringing  human  rights  and  violate  people’s  expectance  of privacy.  They  do  not  want  to  do  for  investigating  crimes  to  infringe  the  right  of  people’s
expectance  of  privacy.  Thus,  they  have  a  hypothesis  two:  surveillance  camera  systems  have negative influence on individual privacy right. Legal system is to discuss the surveillance camera
systems involved in legal problems. Though most includes the discussions on the issue of human rights, the contexts stress on the discussions of legal level yet. Their conclusions are always to
203 point out the lack of recent legal system, people to the management unit for collecting picture
data from the surveillance camera systems having low credit, but on the contrast, basically they are on the same page on that if there are enough legal control and there are good efficiency on
collecting and using picture data, so that they do not deny the installment of surveillance camera systems in public areas. Therefore they have a hypothesis three: the majority of people have low
credit on the management units in collecting and using picture data. Phenomenon study aims at the phenomenon study of prevalent installment of surveillance camera systems in public areas
and has its ideas. According to its attitude, its viewpoint is agreeable with maintaining public security  by  surveillance  camera  systems.  So,  there  is  a  hypothesis  four:  surveillance  camera
systems are helpful to the sense of people’s security. The study of the appliance of surveillance camera  systems  for  the  crime  investigation,  the  documentaries  applause  for  the  surveillance
camera systems function and in the efforts of government’s installment of surveillance camera systems by decreasing crime rate and increasing crime resolving rate in the way of statistics and
analysis. As a result, there is a hypothesis five: there is an important links on the government’s prevalent installment of surveillance camera systems is helpful to decrease crimes and increase
crimes resolutions.
5. Conclusions
There  is  a  specially-assigned  police  officer  at  any  police  station  to  maintain  and  manage  the surveillance  camera  systems.  For  the  purpose  of  simple  operation,  the  police  station  aims  at
training  every  police  officer  to  operate  perfectly.  The  maintenance  budget  is  planned  by  the Miaoli  County  Police  Department.  The  Police  Department  has  ordered  Miaoli  County  Police
Department maintenance plan for surveillance camera systems and asks its personnel trying their best  to  maintain  and  manage  the  systems  and  check  the  systems’  function  in  period.  The
surveillance  camera systems are many  advantages, but there are some side of  effects, such as tangled lines, spoiling city aspect, reading problems, false using, legal questions and infringing
privacy right. The surveillance camera systems are installed at the hot spot of crimes, but if it happens the crime displacement or profits proliferation? That is related to different levels of life
styles  and  social  control.  For  example,  in  the  metropolitan,  commercial  centers,  traffic  ways, there are intense installment of surveillance camera systems, but if there is a ray of chance to
commit a crime, the gangster will do. Whereas, in the rural areas, there are informal sanctions, they  have  a  very  few  criminal  cases  even  if  there  are  no  surveillance  cameras.  To  sum  up,
different environments and social control influence the crime rate. Surveillance cameras bring two  sides  of  influence  on  people’s  life,  privacy  right  and  sense  of  security.  Almost  80
percentages of people are willing to discard the privacy right for the sake of security. Because the surveillance  cameras  provide  them  with  confidence  and  sense  of  security.  People  gradually
depend on the surveillance cameras and those are parts of people’s life. In other words, people do not  dare  to  walk  out  at  the  midnight  if  there  are  no  surveillance  cameras.  The  installment  of
surveillance  cameras  is  a  part  of  community  self-defense  system,  and  its  goal  is  to  prevent crimes. The surveillance cameras have the coercion on gangsters. In the beginning, we have got
many profits from the surveillance cameras, but over the  years gangsters know well of places installed the surveillance cameras, the efficiency of surveillance cameras is decreasing. Looking
at the investigation effect, there is still low rate of clearing up criminal cases. We should make efforts to do with quality, skills, environmental improvement and hard work, and then we could
go ahead with crime prevention. Now the surveillance cameras have played an important role in community public security. They operate all around the clock and they are linking to people’s
