How fast is one mile per minute? Well the obvious answer is 60 miles per hour, but let’s look at a graphical representation of exactly how fast 1 mile per minute really is:
A Missing Child Can Disappear At 1 Mile Per Minute
Click on the image for a larger version and you will see 12 concentric circles based around Lincoln, Nebraska. The inner most circle represents just how far a missing child can disappear in 1 hour. Each additional circle represents an additional hour, with the outer most circle representing only 12 hours. That’s 720 miles.
Even 1 mile is well out of the range of any RFID based child location system on the market today, in fact most of them do not even have a range of more than 600 feet – that’s just 2 football fields. At 1 mile (5280 feet) a minute (60 seconds), a missing child could be out of range of any of these RFID based child location systems in just 8.8 seconds (5280 feet / 60 seconds). So within 10 seconds of your child going missing he or she could be well outside of the range of any RFID based child location system. Just 10 seconds. And that means there’s not even an indication of which direction to start searching.
That’s why a GPS child locator is so much more effective in locating a missing child than an RFID based system. The sentryGPSid child locator is not a locally based system with a limited range. It has the ability to locate a missing child anywhere in the world, through any internet connected computer. As long as the sentryGPSid can pick up a cellular signal in order to broadcast it’s location back up to our webportal.
Additionally, not only does the sentryGPSid allow you to locate your device anywhere a cellular signal can be obtained, our geofencing technology also lets you know BEFORE your child goes missing by sending you customized alerts as soon as your child leaves their predefined safe zones. You can also send a text message to your device at any time and it will respond back it’s exact location as well as a link to a map which will show you it’s exact position.
