GPS dashcams are dashcams with a GPS receiver. The GPS receiver collects the current coördinates of the dashcam trough a combination of satellites. Dashcams with GPS are able to show the current speed in the video, which can be crucial in providing video proof. Also, videos from GPS dashcams can later be watched together with the current location and route in Google Maps. Most dashcam brands have a dedicated GPS viewer for Windows and Mac. There are also universal programs available, of which Dashcamviewer is currently the most stable and reliable.
Built-in, external or optional
Most dashcams have a built-in GPS receiver, usually fitted in the mount for the best reception. Other dashcams have an external or optional GPS receiver. An external GPS receiver is usually fitted on the windscreen with a 3M adhesive sticker. Some external GPS receivers have the benefit of being faster and more accurate, although most built-in GPS receivers in recent dashcams prove to be very reliable.
