It is true that technological devices such as surveillance video or mobile phone are utilised for monitoring public activities these days. In the most common case, many people do not realise that they are being monitored. Although the existence of these devices has some drawbacks, I do believe that it has more benefits for our communities and the following essay will discuss it in details.
On the one hand, it is reported the usage of technological tools has increased, such as video cameras that are placed everywhere by authorities and the tracking of individuals' cellular phone using satellite technology. These acts are unfavourable for some people since authorities do not inform their residents about the activities. Some people believe that this is against human rights and freedom, where people should have their own privacy. Besides that, this monitoring data could be misused by the member of the authorities, as the data could be sold to another party for business or political purposes.
On the other hand, the existence of CCTV in public places and satellite tracking of mobile phones would bring many advantages for the humankind if they are used appropriately. With the existence of these video monitoring activities, it would help the police department in preventing and investigating any crime activities. And then, with the sophisticated satellite tracking technology, it could help authorities in tracing crime persons, as they could search the existence of criminals through the signal of mobile phones. It has been proven that with the usage of these sophisticated technologies, it has reduced the number of crimes in many countries.
In conclusion, it is common that governments use advanced technology devices such as video camera and handphone tracking system to monitor their residents' activities. And in common cases, these monitoring activities are not informed and socialised to the public, therefore some people believe that they are against human's privacy policy. In my personal opinion, I do believe that these activities have more positive sides than its negatives if authorities use it properly.
