Their device is worn on the wrist or ankle. It's not a PLB that is activated by the wearer. Instead it transmits a signal that police can track when the person is reported missing. Each device has it's own frequency. Missing persons using this device are found in under 30 minutes.
No cellular connection. They're using GSM for (allegedly) cell-tower location data. Looks like it's not very useful once it gets far from the base-station and handset... about a hundred feet to maybe 325 feet or so max-range from the description. Keeps people chained to a few rooms or a small house. I'll bet the false-alarms make trouble. If someone skips out at the right moment (or gets behind the wheel of a car) you're depending upon the cops to have and be trained on an expensive unit to ping them from distance and on the cops to drive up and down the streets trying to get a signal.
Also, no panic-button? Did I miss that in the description somewhere? What if someone gets in trouble inside the home?
Would have been an interesting first-gen product, but they're on the 3rd revamp and still haven't done much with it. While I like the wristwatch form-factor, I think the AT&T Amber Alert GPS locater is a better box.
You're confusing products.
The PLI system uses radio frequencies that have a 0.5 to 1 mile diameter range on the ground and 7 miles in the air. Law enforcement is trained on how to search, detect, and home in on the unique frequency of the missing person. There are no false alarms. Family calls a certain phone number when the person has wandered away from home and then police are notified and given the frequency.
No satellite or cell tower is needed.
Costs to law enforcement are not that large, some are covered by the state, grants, or business partnerships. It's far less than the cost of conventional searches.
The PAL system is GPS/GSM and is used by the family to set boundaries and to assist with their own searches. It's not tied to local law enforcement. It's to prevent wandering to the point where law enforcement assistance is needed.
Neither are a PLB or I need help device. This device is for the persons I listed who do not have the mental capacity to call for help or realize they need help. This is for the wanderers. Passive devices. And as I said they account for the largest amount of callouts.
Thanks. The FAQs were not particularly good at describing the products.
It's been my experience that when impaired people wander they end up more scared than the people trying to find them. I think the panic button is an important feature. In combination with GPS and the geofence, that'd be a nice product... And that's what AT&T's Amber Alert device does - SMS when the geofence is breached, GPS for finding the person and a panic button.
I've been looking shopping for products like this for my elderly parents and haven't found anything better so far. A pendant or watch form-factor would be a nice enhancement.
Your experience doesn't match reality. Families need to assess the person at risk and their capabilities which can change with time. Dementia and alzheimer's persons can be terribly confused or so deep in their psychosis that they are in another time/place. Autistic and down syndrome persons may actively try to hide or evade everyone. Most of these people will not respond to searchers calling out their name, refuse to ask for help from people who are nearby, or go up to a house and knock and ask for help. Many will wander and get into trouble without even realizing they are in trouble. It's these people who need a passive location system. A panic button would not be used. The mental capacity is not there. This is why so many police departments are partnering with Lifesaver.
For the aging parent without mental incapacity, or with early dementia/alzheimer's the PAL or other devices like you mentioned are viable options.
