From Gizmodo:
The Boardbug is a watch-like baby monitor that has two distinct modes. In the first “baby” mode, the devices work like a traditional baby monitor, broadcasting audio from the child’s unit to the parent’s and even sounding a warning buzzer if the baby outsmarts the latch and takes the unit off. Plus it has a built in thermometer to monitor temperature levels in the baby’s room.
The “toddler” mode takes all those features and adds on a proximity-based “safety range” and a panic button, which sounds a startling klaxon so you can easily determine which freeway your child is playing in, but sadly does nothing for the periodic anxiety attacks that come from realizing you’ve got 16 more years of this shit.
