What features are available?
Ping is one of the world's smallest GPS locating devices on the market. To get something this small, we have to balance performance with battery life and do some wicked smart stuff with how we report.
When Ping starts to move what we feel is a "significant amount," roughly 300 feet, we try to get a GPS signal and report the movement over cell. We can't always get a GPS or a cell signal - similar to your cell phone unable to connect - so we keep trying as long as the device is moving. When it stops moving, we report in the location if we can get a cell signal regardless of GPS so you know roughly where it stopped. This is essentially like have a power-optimized, real-time reporting solution. You do need good access to the sky (i.e. it wont work well underground or deep indoors) and solid AT&T cell service for it to work, just like any cellular device.
We DO NOT offer geofencing. Why? Because we have NEVER seen a GPS device that does this accurately or in a timely manner. Because these devices are so dependent on cell or wifi, there is zero guarantee anyone can give that a device will be able to connect to transmit location information at the precise moments when a device crosses the virtual "geo-fence" line. We found that in practical use, since geo-fencing cannot work perfectly all the time, it causes more stress than less so we simply don't offer it.
We do offer location history for the last ten reports, real-time movement based reporting, battery alerts when the battery gets low, SOS and checkin notifications and detailed device performance so you can see what is and is not working. We also offer free mobile apps and over-the-air software updates as we make improvements.
