Care of the vulnerable


Safety & Security:  One of the main uses of GPS trackers is for the safety and protection of people at risk if they get lost or disorientated. It can literally be a life-saver, and of immense value to family members who worry about someone's whereabouts.


Ethical considerations:  There are no ethical problems in using a tracker to help keep someone safe. There are no data protection issues because it is not personal data. The data provides information about a SIM and a modem. It doesn't contain any data that reveals a person's ID or biometric details. If still concerned, a family should get their loved one to sign a simple authorisation allowing family members to view the modem's location.


Panic button:  Some models have a Panic button, which allows the wearer to request help, should they feel the need, pressing it for 3secs. Trackers can extend the years that someone can live independently. Simply knowing where someone is, and whether they're at risk, achieves independence and peace of mind in an affordable and sustainable manner.

Geo-fence operation:    All models are capable of geo-fence/safety zone operation. These can give alerts to (up to 3) family members when the wearer exits and/or re-enters particular locations. This keeps family members up to date with excursions to and from the home, for example, so they can take action if or when the wearer leaves but doesn't return.

Tracker type and location:   Finding a tracker that is a suitable size that will be acceptable to the wearer can be very challenging and critically important. The smaller a tracker is, the more frequently it will need to be charged, but the more likely it is to be acceptable - a trade-off. Sometimes the tracker can be located or even concealed in a Wearer's clothing or possessions (e.g. key-ring). It can be placed into a shirt pocket or attached to a belt, or to a lanyard around the neck. Dementia and other disabilities can cause patients to have limited tolerance of unfamiliar objects. The tracker needs to be familiar and tolerable.

Carer interface:   The Carer can view the location of the tracker, or its history - where it has been, using the TrackServer app on their mobile phone, or through a web-app ( On a bigger screen device like a computer, there is the web-app at These are very simple but powerful user interfaces, that are continuously being improved. This website's HowTo section explains how these work. and we are at hand to answer enquiries by phone, and online, most of the time.

Operating the tracker:   The tracker needs to be switched on and be at least partially charged. The tracker has an internal battery with a life from 1-7 days under normal use, and may need to be charged nightly.  If the battery level drops below 20% a low battery alert message will be sent to the Carer's phone.

Battery life:  The battery life depends on how frequently it reports its location, the environment and the proportion of time the tracker is in motion. It saves the battery when not moving. The option of Eco mode extends the battery life by turning the tracker Off between location reports. Each come with a USB mains charger.
