If you are considering getting one of the many child tracking devices on the market for your child than you really should do a little research to make sure you get the one that is best for you. There are four different types of devices for tracking your child and each has is good points and drawbacks.

A radio frequency based device or RFID uses radio frequencies to track a child that has wondered off. These means they are only effective from 300 – 600 feet away so you have to be close to use the device. The big plus for this device is there are no monthly fees in order to use it.

Simple audio devices also exist where a unit in your child pocket will sound when a parent pushes a panic button on their unit. These are similar to the RFID models in that they are only effective in close range but do no require any monthly fees.

A GPS logging device will keep a map of everywhere your child has been that you can then download to your PC and a mapping program. These devices are not as handy for smaller children but are very effective at keeping up with the movements of a teen who has begun to explore the freedom that comes with being older.

A real time GPS child locator such as the Amber Alert uses satellites to locate the device that your child has in their backpack or pocket so you can find their location at any time. Using GPS satellites and web-enabled cell phones these devices are the most effective but there is a monthly fee involved with the use of the system.

As parents the cost and effectiveness should be carefully compared so that you can get the child locator device that will best suit your personal needs.
