Security Camera Installation Advice?

“Dear PoPville,

I live in a 10-unit condo building and would like to take advantage of the security camera rebate program offered by the DC city government. I was wondering if others have recommendations on installation. Is it easy enough for someone with little/no experience figure it out, or is it better to hire a professional? If so, any specific recommendations would be greatly appreciated!”
