We teach you how and where to look to find a hidden GPS locator in a car using frequency detectors.
Before continuing reading this post we recommend that you read our article ” How to detect a GPS locator? ”Where we explain what it is, how it works, and how to detect a spy GPS locator in a car.
It should be noted that here we will only teach you how to find the car locators of transmission to bursts hidden in a vehicle and not the spy cameras, recorders or microphones since the procedure and means to use would be others.
How to find a hidden GPS locator in a car?
In this article, we will teach you how to do an electronic sweep with various means so that you can find a hidden GPS locator.
However, remember that you can always hire the services of a truly accredited private detective to issue you a “clean” certificate. At Espiamos we work with several offices. Contact us and we will recommend one depending on your residence.
But before starting the procedure you must understand some basic concepts.
What are the differences between an active or passive device?
An active electronic device is a device that constantly transmits a signal like a WIFI spy camera; or bursts, from time to time, such as a GPS locator.
A passive electronic device does not transmit any signal but receives it.
To detect an active electronic device, a frequency detector or scanner must be used and to detect a passive device, a non-linear joint detector, also called NLJD detectors, must be used.
A nonlinear detector would allow an active electronic device to be detected, but a frequency scanner could not detect a passive device.
What is a GPS locator or tracker?
A GPS locator could be said to be a burst transmission device that has a GPS receiver module and a GSM / GPRS transmitter module and that serves to know the exact position, via satellite, of an asset.
Burst transmission means that you send data periodically over a specified time interval. Generally, it is usually between 10 and 60 seconds.
Now that you know that a GPS locator is a burst transmission device and that you must use a frequency detector to find it, we teach you how to find it!
Where to find a hidden GPS locator in a car?
The first search you have to do must be the visual one. You should look for any foreign object that is connected or attached in the most sensitive places such as:
- Vehicle underbody, wheel arches, or driveshafts for magnetized GPS locators.
- Car OBD connection for OBD type locators.
- Fuse box, car battery, dashboard, and blinkers for installation GPS locators.
- Under the seat, cigarette lighter socket, glove box, and object holder on the sides of the doors for camouflaged GPS locators.
Here you can see several examples of what we can find:
As we recommend in the post ” Methods to detect a GPS locator? ”The best equipment to carry out this search is the iProtect 1207 with the external antenna and the digital frequency detector. Here we have used the digital frequency detector due to the simplicity and speed with which it locates all kinds of GPS.
You must bear in mind that most GPS locators are configured to transmit when they detect movement and fall asleep when they are at rest, thus achieving greater autonomy. This data is important to make a correct electronic search since if the GPS does not transmit, it cannot be located.
We teach you 3 different methods to find a hidden GPS locator:
- Go to a place as isolated as possible from frequencies such as the rest area of a highway.
- Put your phone in airplane mode.
- Select the “Cellphone” mode, set the sensitivity of the digital frequency detector to a minimum, and choose the audible mode.
- Find all the objects that are in the trunk, glove box or sides and put them in a box or suitcase.
- Turn on the digital frequency detector and let it work for 5 minutes. See if it detects the GSM frequency constantly and repeatedly over a period of time, for example, every 30 seconds.
- Place the frequency detector on the dashboard and move the car for a few kilometers observing the frequency scanner.
- Return to the rest area or place without interference that you have chosen to start the search slowly outside the vehicle.
In this video, we show you how a GPS locator that is hidden in the car sends the positions approximately every 10 seconds and how easy it is to detect the signal with the digital frequency detector.
When you dial 900MHz, you are sending the GPS position. It is important to carry out this search with the car in motion to “wake up” the GPS since it could be configured so that it does not send positions if the vehicle is stopped.
The exterior part of the vehicle
- The searches will be divided into 4 parts: front, rear, left side and right side, taking into account that there are 3 planes: upper, middle, and lower.
- In each part you must be at least 3 minutes and, between part and part, you must move the car to “wake up” to the possible sleeping GPS locator. Example: move the car a few kilometers and check the front. Move the car another kilometer and check the rear like this until all the parts are completed.
- Carry out the same process with the objects you put in the box or suitcase in point 3.
Method 2 using a frequency inhibitor
Note: The use of frequency inhibitors is totally restricted in Europe and the penalties for marketing or exporting these products range from $ 500,000 to $ 20 million. This procedure is only indicated for readers from countries outside the European Union.
Using a frequency inhibitor, the intention is to force the loss of the GSM signal from the GPS locator to detect it when it is restored.
The GPS locator when it does not have a GSM signal, what it tries to do is connect to the network constantly until it succeeds, and that is precisely when we can detect it.
Here you can see an example using a mobile phone. Every time the airplane mode is removed, it connects to the GSM / 3G / 4G network, obtaining a car location.
Steps to find a hidden GPS locator with an inhibitor
- Go to a rest area and put your mobile phone only to work with 2G and 3G (not 4G) networks.
- Turn on the frequency inhibitor and check that your mobile phone has lost the signal.
- Put your phone in airplane mode.
- Turn off the frequency inhibitor.
- If during the first seconds the scanner detects a GSM or 3G frequency, it means that you have a GPS locator.
An alternative method to frequency inhibitor
You can do the inhibitor process by going to places without GSM coverage like tunnels or shopping center garages.
