In India, it is known that officials in the government slack during office hours. Delaying of process for unworthy reasons. Numerous time-breaks and other infinite 'small' but aggregatively deterrent forms of behaviours in the office.
The camera moves the whole system a step forward. Transparency is more easily perceivable to the public now. The necessity of a sting operation in the office does not emerge. People can have a fresh perspective on the laws for the government officials.
Psychologically, this might build a better work environment. It has been shown that adding monitoring video cameras does add a certain form of placebo effect.
I hope the 'mantra' should be improvement, no matter how small it is. A complete revamp of the system is more like dreaming about humans taking over all the nine(eight eh?) planets, and that too in an year.
