Positive Points:
-Provides security
-24 hour surveillance on important places
-Aid in the capture of criminals and fighting of crime
-Provide evidence in crimes
-Discourages theft
-CCTV today often supervises industrial processes that take place under conditions too dangerous for humans
-Many cities and motorway networks have extensive traffic-monitoring systems, using closed-circuit television to detect congestion and notice accidents
-Bosses can also check on their employees in case they have been resting instead of working
- Monitoring the situation at home : maid, children, sick family members
Negative Points:
-CCTV cameras are intruding into people's privacy, as they are not surveying private, but public space, which goes against the publics rights
-CCTV’s are outnumbering people in countries such as the UK
-The ever-increasing number of CCTV’s aiding in the prevention of crime may lead to over-reliance
-Hackers and guerilla artists have exposed the vulnerabilities of the video systems in an act dubbed "video sniffing”, they have crossed feeds, uploaded their own video feeds and used the video footage for artistic purposes.
-Spraying substances over the lens can make the image too blurry to be read
-For wireless networks, broadcasting a signal at the same frequency of the CCTV network is reported to be able to jam it
-Laser pointers can temporarily blind cameras, and higher powered lasers can damage them
