The habit that undid the system
A property near Monaco had a genuinely capable alarm system — tens of thousands of euros of equipment, correctly wired, properly maintained. It had been specified by an automation contractor: the kind who installs electric gates and roller shutters to a high standard, but isn't trained to interrogate how a family actually lives in a house. Nobody had asked about the cat. The family had ruled out a cat flap on aesthetic grounds, so every summer they left a small skylight cracked open instead, letting the animal in and out without waking the house. The perimeter zone covering that window stayed disarmed for the season — a habit, not a decision anyone had consciously made. It was through that same window that the intrusion came. The father woke to find the team already in the parental suite. They fled the moment he stirred — the encounter never escalated further, but the damage was already irreparable. A security specialist doesn't just wire a system — they interview the household until the small, easily-dismissed habits surface: the window left open, the zone quietly disarmed, the seasonal routine nobody thought to mention. The fix here wasn't new hardware — it was a pet-aware zone configuration, installed in under a day. The lesson behind it is the one that matters: a system is only as good as the questions asked before it's switched on.
