I’ve got to get a pair of these to keep track of my one year old daughter:
It’s a 21st centrury version of the baby monitor. They have two versions: one for babies, which monitors basic stuff like audio and temperature, and one for toddlers, which adds a proximity alarm (if they wander too far away), and a “panic button”, which, uh, probably sounds a loud alarm, and scares your child into staying put while you find them. Both versions sound an alert on the parent unit if they’re removed or tampered with.
Not as fancy as some of the wireless cellular/GPS-enabled child trackers, but probably not as expensive, either.
What do you think the odds are that I’ll be able to convince my wife that we need these? 😉
