: Cameras that capture a neighbor’s private areas, like bedroom windows or backyards, can lead to legal disputes or claims of harassment. Legality often hinges on whether there is a "reasonable expectation of privacy" in the area being recorded. Legal and Ethical Considerations Privacy laws vary, but general standards often include:

Only cover areas where privacy is impossible. Front doors, driveways, back alleys, and garage doors. Do not cover windows (yours or theirs), fenced pools, or changing rooms. Use physical shields (stickers, housings) to mechanically block out 5% of the frame that might catch a neighbor's window.

To fix this, we need a new etiquette. Talk to your neighbors before you install a camera that points toward their fence. Offer to share footage if they have a break-in. Turn off the microphone. Buy local storage. Use privacy masks.

If your porch camera covers 90% of your porch and 10% of your neighbor’s living room window, you are violating their privacy. In some jurisdictions (e.g., Germany and parts of the EU), this is a criminal offense subject to heavy fines under GDPR. In the US, it is grounds for a civil lawsuit (intrusion upon seclusion).
