Vibration sensing gps tracker

Now upgraded to vibration sensing gps tracking system. The limitation of this version is the gps coordinates are not in google earth format. However, the vibration reporting is extremely useful as the tracker will first give your preset phone a remote call. If no response, it will then send you the new gps coordinate by sms.

This tracker system can also be internet server base but your need to purchase a gprs data sim card which cost > $298 hkd valid for 6 months. A local prepaid sim is only $98 valid for 6 months and no server charge cost. For anti-theft purpose, this is a good deal. For spying someone, gprs data will cost less sms.
