With monitoring packages as low as $10 a month, tracking devices for children are a natural choice for today's parents. These tiny devices can be worn around the neck, wrist, arm, ankle, or in a backpack or coat, and allow you to monitor your child from an internet-enabled smart phone or computer.
These devices work best outdoors of course, generally marking the child's location within five to fifteen meters. The Amber Alert GPS is even water resistant, providing some protection to the GPS transmitter.
