I am looking into a security camera system for my home. In doing research, I stumbled across this site. I work for my local sheriffs department as a Corrections Officer. Here lately I've been hearing chatter amongst my customers that there is some activity in my area. So I am wanting a set up where I could positively I.D. a person from about 30ft away. I thought I could just get a 4k system and be good to go. I was wrong. Hopefully this group will help me learn what I need to protect my Home or find the person that attempts to invade it.
