When you get a child GPS tracking device, you'll be able to monitor your child's location and movements from an internet-enabled smart phone or computer. These devices use a GPS transmitter, generally accurate within 5-15 meters in up to 90% of occasions. Keep in mind that these devices work best when the transmitter is outdoors.
Monitoring packages can start as low as $9.99 per month, depending on whether or not you want basic monitoring or the option of setting alerts, which can send you emails if your child leaves a pre-determined safe area or breaks your limit for the speed alert (great for teens!).
