Not just installing but proper maintenance by the Security team is also important. The concerned persons who are responsible have to watch it every time with proper attention. If anything goes wrong, immediate action has to be taken.
CCTV’s are must in and around your house premises. Many of the Delhi’s residential colonies are mandating the CCTV installment in their respective apartments and individual houses.
I think it is really important to install CCTV's at apartments or flats for our own safety. I feel this should be made mandatory in all the apartments and cities.
CCTV's act as your new colony watchman which will keep track of whoever entering or exiting from your apartment. After all, end of the day, its security what you get from this.
