This is the covert tracker 3 GPS, GSM asset tracker. All trackers use GPS Signals to obtain the longitude and latitude data. Trackers will use the GSM signals to send the longitude and latitude data to the Internet server.
These are (TSCM) Technical Surveillance Counter Measure devices. Used for locating spy transmitting devices.
The DD1203 and the DD1207.
The DD1203 will detect any device signals transmitting 30MHZ to 6 gigahertz.
The DD1207 will detect any device signals transmitting in CDMA, GSM, WCDMA/3G, 4G, Bluetooth/Wi-Fi, and Wi-Max, 3 and 6 to 7 gigahertz.
Understanding GPS. GPS satellites in space send GPS signals to GPS receiving devices. And they triangulate the GPS signals and determine longitude and latitude locations. A GPS only device does not transmit signals.
The GSM signals will send the data to the internet server and the software will decode the data also log the data and show you a locations on a mapping program.
Buying a TSCM device to find a GPS asset tracker will only find real time tracking devices that transmit GSM signals to send real time data they obtain.
Here is a example of the TSCM devices working and locating the transmitting signals.
You will see in this video the covert tracker 3 will only alert the DD1203 and DD1207 when they detect the transmitting GSM signals. And they will light up and vibrate. Real time trackers only send signals. On programmed intervals. They could be every 5 seconds to every minute, five minutes, or even every hour. The signal will be a short few second burst. Like a text message. They do this to save battery life.
This is how all real time GPS, GSM trackers work. And these TSCM devices will find any real time trackers.
Thank you for your time, If you have any more questions regarding TSCM services to find vehicle /asset trackers you can contact spyops.net 2485696831 for more assistance.
