CCTV system is initiated to stem a perceived increase in disorder crime in a town center, the crime prevention mechanism requires that potential offenders know they are being watched. Evidence suggests that even though implementers install a system, have a publicity campaign, and place signage, there is no guarantee the population will be aware of the cameras.
CCTV should provide the capable guardianship necessary to prevent a crime, but this concept requires that offenders demonstrate rationality in their behavior.
CCTV has the potential to reduce crime. The cameras may be able to assist in the detection and arrest of offenders.
CCTV evidence is convincing, though CCTV’s ability to reduce overall crime levels through detection (rather than prevention) is less convincing and arguably a less effective way of impacting crime.
CCTV system may reduce the likelihood of burglary at a commercial location within the range of the camera, there is some evidence that drug markets can continue operation in the presence of CCTV by changing their operating practices.
CCTV may reduce crime is through an increase in collective efficacy. CCTV cameras being installed in their neighborhood, this will signal to them a degree of investment in and efforts to improve their local area.
Benefits from a CCTV system:
- Aid to police investigations
- Provision of medical assistance
- Place management
- Information gathering
- Diffusion of benefits
Reduced Fear of Crime
Due to CCTV systems there is a reduced fear of crime in an area may increase the number of people using the area, hence increasing natural surveillance. It may also encourage people to be more security conscious.
Aid to Police Investigations
CCTV system to have a role in crime prevention, CCTV tapes aiding in an offender’s conviction. CCTV camera evidence can be compelling, though issues of image quality are a factor if CCTV images are used for identification purposes.
CCTV can be used for general location management. The cameras can be used to look for lost children, to monitor traffic flow, public meetings
CCTV Cameras can also be used to gather intelligence and to monitor the behavior of known offenders in public places (such as shoplifters in public retail areas).
- CCTV is more effective at combating property offenses than violence or public order crime (though there have been successes in this area)
- CCTV appears to work best in small, well-defined areas (such as public car parks).
a number of surveys have shown that most of the public tend to be unaware they are in CCTV areas, so significant effort should be made to advertise the cameras’ presence if you want to maximize the system’s preventative aspect.
additional police resources for the long term, a cost that may need to be factored into CCTV running costs, or at least into the local community safety budget.
- The area under surveillance should cover only clearly public areas.
- Surveillance equipment can use zoom, tilt, and pan to enhance video capture, and enhanced microphones to detect sound. However, technology that is able to intrude beyond reasonable limits of audio and visual capability may be constitutionally questionable.
A Digital Video Recorder (DVR) is a device that records video in a digital format to a disk drive. DVRs made specifically for CCTV Security Surveillance System applications record video signals from security cameras.
A Network Video Recorder, or NVR is an internet protocol (IP) based device that sits on your computer network.
NVRs are designed to handle the vast amounts of simultaneous video streams coming in for recording and rebroadcasting the same feed out live to client machines locally or remotely.
