Sir,
As a person who is both second generation electronic security (credentials available) and owner of a security company for over 5 years, you might be interested in knowing that you might get ready to spend tens of thousands of long term dollars for such an investment. I suggest that if you feel the need to have CCTV, you might find a worthy company to provide you with all the video devices that you need to operate as you mentioned. Its not hard and it will offer you, the user and owner so much CCTV for your property. Too ask for a community to do so is not something I feel is necessary or important enough to spend countless dollars for your request.
