See Your Real-time Data, Anywhere

Sniffer4D’s built-in cellular connectivity* & US-based Cloud server enable secure real-time data transmission with unlimited range to decision makers in different locations.

*Supports 4G/LTE/3G/EDGE/GPRS

Advanced Real-time Visualization

Sniffer4D Mapper software visualizes and analyzes data from one or multiple Sniffer4D(s) in real time, providing intuitive & insightful information for decision makers.

One-click Result Delivery

After a mission, simply click a button to generate a mission report containing key results, or a CSV datasheet containing all the raw data. Reporting your work has never been easier.

The drone carries a Sniffer4D and a stabilized camera together – gas data from Sniffer4D, pictures from the camera and flight data from the drone are transmitted to the remote controller of the drone in real time (only for DJI M210). Meanwhile, Sniffer4D is able to transmit real-time gas data to multiple PCs at the mission site, control center or other places through its independent 4G/telemetry radio. Sniffer4D also backs up mission data to the onboard SD card at the same time.


Data can be transmitted to different places in real time.

Our software provides intuitive visualizations for effective and timely decision making.

Data can be transmitted to multiple places

Matrice 350 RTK

An upgraded flagship drone platform, the Matrice 350 RTK sets a new benchmark for the industry. This next-generation drone platform features an all-new video transmission system and control experience, a more efficient battery system, and more comprehensive safety features, as well as robust payload and expansion capabilities. It is fully powered to inject innovative strength into any aerial operation.

GPR system: Radar Systems Zond Aero LF (low frequency)

Extra-lightweight GPR system, suitable for medium-sized drones like DJI M300 RTK.

Comes with 3x sets of dipoles for the 300, 150, and 100 MHz.

Utilizes Real Time Sampling (RTS) with high hardware stacking, delivering high-resolution low-noise data.

Laser Falcon methane detector

Laser Falcon is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.

The concept is based on Infrared Absorption Spectroscopy. The laser emits light (spectral range of 1,65 μm), which reflects back and is captured by the sensor. The outgoing and incoming signals are compared with the built-in reference cell. If methane is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.
