Rules Re: CCTV

If I get CCTV installed, do I need to legally display a sign stating I have CCTV footage? I have an on going dispute with my neighbour regarding abusive language toward me, and would like to get CCTV installed in my home to capture the shouting over at me, am I legally required to notify my neighbour of CCTV being installed?
