Some people find it strange to consider having CCTV inside their home as they see it as an invasion on their privacy and do not like the thought of everything they do being recorded, but often indoor CCTV has been more helpful at catching criminals in the act than outdoor cameras.
Sadly there has been an increase in elderly people being targeted by con men/women for money and sometimes in door CCTV has captured the whole event. There have been cases where they make an excuse to enter your home and then steal property whilst you go out of the room.
With the help of indoor video camera footage, many of these con artists have been caught and the CCTV used as evidence in a court case against them.
Security for your home is vital, but do not forget about the inside as well as this is where most of your possessions will be.
