Plusy :
-goods somehow of image
-simple installation
- much memory

Minusy :
- lousy construction
- unreliability
- dull
-faint sound
So I start with pluses:
- we can catch bellmans
- check the situation all the time
- if we talk about monitoring the city: save money that would be spend on fuel (to check e.g the city by car)
- it is more effective than check city by the car, because you can not see everything and if you have it on tape it is easier
- e.g in the bank, if it was robbery you can see the past

- although you can see everything, you cant hear everything
- sometimes bad quality of view
- it fetters some people
- someone can do bad thing when it is broken for a while
- it doesn't work without current (and it happens sometimes)
