LXDT-603 - Handheld passive cell phone signal detector in 2G /3G /4G /5G networks

Product Premium
Availability: In stock.



The presented portable passive detector LXDT-603 is very sensitive specialized equipment that allows the detection and location of all types of devices communicating in 2G, 3G, 4G and 5G networks.The product is ideally suited for detecting cell phones, hidden 3G/4G cameras and GPS locators in both buildings and vehicles. Due to high sensitivity, the device can be used for rooms up to 1000 m2 without the need for time-consuming searching them meter by meter.

The LXDT-603 passive cell phone detector allows very accurate manual adjustment of the threshold sensitivity above the background noise level separately on each band and programmatic sensitivity adjustment (detection range) for all channels together, which means that it can be adapted to any place and for different operating conditions (detection of strong and weak signals). When using the device, we can decide which channels should be enabled and disabled to expand or narrow the scope of operation. Detected signal types and their strength are displayed on the LCD screen and signaled by a sound and a lamp, in silent mode by vibration or discreetly through a connected handset. The intensity of notifications depends on the distance from the source of the signal generation and its power. The detector's small dimensions, light weight and no protruding antennas allow it to be worn in a trouser or jacket pocket or in a holster attached to a belt. Operation of the device is very simple and does not require special training - the control is done using an intuitive keyboard (5 buttons).



The LXDT-603 handeld mobile phone detector uses passive detection technology using precise band-pass filter, which automatically captures all types of communication above the noise level on all cell bands simultaneously. The detector, due to the built-in SAW filters, is completely insensitive to signals from base stations, from DECT cordless phones, DMR radios, walkie-talkies or other devices not operating in cell bands, which means it does not cause any false alarms. Our detector is more effective than competitive solutions (BVS Wolfhound-PRO, YORKIE, PDA CPD197EU or JNN CAM-105W) which are using an inaccurate frequency scanning method that does not always capture all signals, especially the weaker ones.



The LXDT-603 tactical smartphone detector allows passive detection of all types of communication and technologies above the background noise level on all cell bands simultaneously, UPLINK frequencies ( Europe ):


Detected signal types:

- line signals on 2G network ( standby / sleep mode )
- voice connections on 2G / 3G / 3.5G networks
- video connections on 3G networks
- short text messages on 2G / 3G / 4G networks
- MMS multimedia messages on 2G / 3G / 4G networks
- packet data transfer - GPRS / EDGE / UMTS / WCDMA / HSPA + / LTE technologies - all 2G / 3G / 4G / 5G networks
- fast data packets in 3G / 4G / 5G networks, so-called burst transmission

Detected and localized devices:

- GSM / 3G mobile phones, GSM / 3G / 4G / LTE smartphones
- GSM / 3G / 4G wiretaps
- 3G / 4G cameras
- GPS / GLONASS / GALILEO locators with 2G / GSM / GPRS / EDGE / 3G / UMTS / HSPA + / 4G / LTE modules
- 3G / 4G modems / routers
- spyphone spy software activity



The device is also designed to detect communication in cellular networks in places and rooms where there is a categorical ban on the use of cell phones, smartphones, tablets and other devices communicating through the cellular network. The equipment is ideal to use in:

- an examination center
- a prison
- a detention center
- a correctional facility
- a government institution
- an embassy

Due to the high sensitivity and long range detection, the LXDT-603 detector can also be used in various types of rescue operations to search for people under debris or lost in a given area who have a mobile phone or GPS locator with them.



This product is available in 2 versions, standard LXDT-603 and extended LXDT-605W with the additional option of detecting signals in 2.4GHz WiFi wireless networks. Our detector can be configured for frequencies used in any region around the world.
