SY-A04 is a car tracker with dedicated OBD connector.

Power supply: 12-24 vcc.

The SY-A04 is a GPS tracking device that offers advanced features for monitoring vehicles, equipment, and other assets. This tracker is designed to provide precise and reliable tracking, suitable for both personal and professional use.

A key feature of the SY-A04 is its real-time tracking system. Users can monitor the exact location of the tracker through a mobile app or website, which is crucial for real-time movement monitoring and logistics management.

The device also includes geofencing functionality, allowing users to set virtual areas and receive notifications when the tracker enters or exits these zones. This feature is useful for vehicle security and asset management.

The SY-A04 is equipped with various alarm modes, including alarms for movement, speed, and low battery. These alarms provide users with timely alerts about any unusual activities or critical situations.

Another important feature is the route history recording, which enables users to view past routes and analyze movement patterns. This is beneficial for route optimization and analysis purposes.

Very good tracker at low cost via OBD connector.

SY-A04 comes with a link to Google Map where you can check the vehicle in real time. The point on the map is established at the time of purchase and, for those traveling in the city, it is recommended 1 minute. Instead, for those traveling on the highway, 3 minutes are the right choice.

The front is very simple:

USB : To charge the internal battery  when it is not connected to the OBD socket. Connected to the computer, the error "USB device not recognized" appears, but it is normal as it would require a specific program to communicate with the PC.

GSM: the yellow light warns that the connection with the SIM card is active and the tracker is correctly receiving the connection from the telephone operator.

GPS: the blue light signals that the connection with the satellites is active. 

SIM

The tracker need a MINI SIM 

Which SIM to buy.

The tracker sends only data packets, so a rechargeable SIM card with a € 3 per month  is the most appropriate solution.

Additional costs

The tracking on the map is made via a dedicated server www.controllosatellitare.com at a cost of € 2 per month.
