My house placement/layout is not too well fit for peeping. The only front window is the big picture window and the door window, to get there, I'm pretty much visible if it's night and I have lights on. That's one thing I liked about my parents' house, my room window was on the street side so I could peep and see anything that was going on.
Eventually I want to install cameras though so I can view who's at the door etc from my office, and also record any activity in case someone tries to break in or something. I have not thought it out fully yet though, I don't want huge cameras sticking out around the house as it will look ugly. Need hidden cameras. Maybe recessed light fixtures in the soffits with some acting as cameras.
