I.A.S. - 入侵警報系統

The motion sensors are plenty sensitive, so my son actually thinks he’s a spy setting up a real perimeter. It’s been a rare afternoon where he’s fully engaged without asking for a tablet, and I even joined in to test how quickly we could trip the alarm.

The alarm setup is so hands-on that my son spent a full afternoon testing how quietly he could sneak past it without triggering the sensor. It's genuinely screen-free fun that gets them moving and thinking.

My kids actually forgot about their tablets for once. Setting up the alarm and testing whether it triggers correctly kept them busy for a solid hour, and they loved re-hiding it around the house. Great way to get them moving and thinking without screens.
