In terms of security, we know that having good elements guarantee our integrity. However, we should also think that having a good relation with our neighbours can even be very productive.
If we have a good relation with our neighbours that can help us on awkward situations. The cooperation between all of us keep the neighbourhood calm and quiet.
You should thing that at any point you might need help to frighten off bad presences in your neighbourhood or residential area.
Anyway, if a burglar see that several houses that surround yours also have a security system, will reconsider the option of going in them.
The collaboration in the neighbourhood is a pillar in security matters.
