GPS trackers are becoming more common in modern society, and they can be hidden in various places, such as cars. In order to find these hidden trackers, we need some specialized knowledge and tools.
First, for ordinary GPS trackers, they send their current location to the server every ten to tens of seconds. These trackers usually need to be connected to electricity because they use a lot of power. We can look for them with hand-held signal detectors. The sensitivity of the detector is adjusted to the appropriate position, slowly scanning from the inside of the car to the outside, and when the signal is detected, the strength of the signal is judged by moving. When the signal is full, the GPS tracker is within 20 cm of the detector, at which time it can be removed for inspection.
For shallow sleep GPS trackers, they are artificially set to send location information at certain intervals and at fixed times of the day. This kind of tracker needs to lock the GSM card number through a special device, and then constantly send a text message or call to the number, so that the device is in a signal transmission state, and constantly transmit signals. The trackers can be found by scanning them again with a hand-held signal detector.
Deep sleep GPS trackers have an automatic on/off function that shuts down when they don't send a signal. These kinds of trackers are very difficult to detect, but there are always times when any device is turned on and sends a signal. We use professional inspection equipment to scan every few minutes. Once the GPS tracker is turned on and sends a signal, the device can capture it.
While this expertise may be somewhat complicated for the average person, it is a piece of cake for those who are professionally engaged in security work. Therefore, it is very important to seek professional help when carrying out security work.
