This dual channel dashcam system connects easily to any wifi enabled Android or Apple phone. (app available on ITunes or Google Play)  It comes with a 16gb, class 10, sd card and can accept up to a 64gb card. It automatically starts recording when the ignition is turned on and stops when it is turned off.  When parked (and the ignition is turned off) it can be set to sense a collision or detect motion and start recording.  While on, it embeds GPS and vehicle speed information into the recording.  GPS and vehicle speed information is available when viewed through downloaded software.  Wifi enabled phones can only review audio/video and change the system's internal settings.
