Does the Guardian Angel device or Tracking Cell Phone work indoors or under dense foliage?
The GPS unit almost always works outdoors, and will still work indoors if it’s close enough to a window. Only the densest of foliage, combined with cloudy skies, will prevent the unit from getting its position. The Guardian Angel GPS unit receives GPS signals from up to 15 satellites at a time. Any of these signals may be blocked by walls, ceilings, trees, leaves, etc. However, if signals from even a few satellites get through to the unit, it will work. It is also worth noting that our device will still maintain contact with our servers even if it cannot determine its location. Even if your child is indoors for hours, we will be able to tell you their last known location (that would usually be the door to the building), and the status of the device (battery strength, cellular signal strength and GPS signal strength).
