Many people place cameras on rear decks to watch for raccoons or burglars. But if your camera looks down into your neighbor’s fenced yard—where they have a reasonable expectation of privacy—you have crossed a line. Courts have ruled that a 6-foot fence creates a "curtilage" (private area). Peeking over that with a camera is legally equivalent to standing on a ladder to look over the fence.
If your camera picks up your neighbor arguing with their spouse through an open window, or records a private phone call on their own porch, you may have technically committed a felony wiretapping violation. Perhaps the most overlooked privacy risk is the manufacturer. When you buy a cheap $30 camera, you aren't the customer; you are the product. Cloud-based storage means your footage lives on a server in a data center you will never see.

In a single-family home, property lines are usually clear. In an apartment, a doorbell camera covers a hallway used by six other families. Legally, you might win; ethically, you are surveilling their comings and goings. For a domestic violence survivor hiding from an abuser, a neighbor’s camera that records their arrival time is a life-threatening data point.
Studies suggest that visible security cameras reduce the likelihood of property crime. For a would-be burglar, a house with a floodlight camera is a "hard target" compared to the unmonitored house two doors down.
For parents, the ability to see when a child arrives home from school is genuine utility. For the elderly living alone, a camera allows family members to perform "wellness checks" without intruding.
Before you mount that 4K PTZ camera that can read a license plate from fifty yards, ask yourself if you are catching criminals or just catching your neighbor living their life. Because in a surveillance society, the watcher is always, eventually, also the watched.
