Chapter 18. Tracking the Kids: Wherify G... > Features and Considerations

Features and Considerations

If you’re contemplating this type of device for your children, there are a number of things to consider. If the cost and monthly service fee are not an issue, then the next consideration is whether or not your kids are willing to wear the device, and then how effective and reliable it will be in everyday use. Wherify seems to have thought about most of the practicalities concerning the use of these devices by young children. For example, if you are worried that your young child may accidentally set off the emergency response request, you can deactivate this feature as part of your preferences setup on the Internet. If someone tries to cut or tamper with the wrist band when the device is in locked status, an alarm will be activated at the Wherify location service center. The device is water resistant, but should be removed for swimming.

The only apparent weakness for the device, in terms of its reliabilityin case of emergency, appears to be the wireless network coverage itself. This, of course, is an issue even with standard wireless phones. If the device is inside a building or in a poor wireless coverage area, it may not be able to send a locate request back to the location service center. The wireless connection is a vital part of the entire solution; without it, the service does not work. Another consideration is battery life. The built-in battery enables the device to work for close to 60 hours of standby time, and to perform up to about 40 locates when fully charged.
