The SEKURTRACK OBD II BT is a vehicle tracking device that plugs into a vehicle's OBDII port. Its compact design allows easy installation. Its internal OBD reader can obtain information from the vehicle's on-board computer and relay it over the networks. Its built-in GPS receiver has superior sensitivity and fast time to first fix. Its Quad band allows the SEKURTRACK OBD II BT location to be monitored in real time or periodically tracked by a backend server and mobile devices. Its built-in 3-axis accelerometer allows motion detection.SEK-OBD-II GPS is a multifunctional product. It is an integration of GPS tracking system, RFID Vehicle Personal Identification immobilizer Security system & OBD-II Diagnostic system. System integration is straightforward as complete documentation is provided for the full featured protocol. The protocol supports a wide variety of reports including emergency, geo-fence boundary crossings, low battery and scheduled GPS position.

IoT, M2M, SIM, OBDII, J1850 PWM, J1850 VPWM, ISO 9141-2, CAN, Keyword 2000, and J170S, OBD-II systems monitor the vehicle's electrical, mechanical, and emissions systems and generate data that are processed by a vehicle's engine control unit (ECU) to detect malfunctions or deterioration in the vehicle's performance. The data typically include parameters such as vehicle speed (VSS), engine speed (RPM), engine load (LOAD), and mass air flow (MAF).
