ZVOOK NW0 LTE is a tactical acoustic sensor developed by a team of active military personnel and IT engineers to detect enemy FPV drones (including those on fiber optics) by the sound of their operation.

The device is equipped with artificial intelligence that continuously analyzes the acoustic environment and instantly reacts to the appearance of an aerial threat. The detection range is 150-450 meters, and the device operates 360 degrees.

Upon target detection, the sensor:

• activates an audible alert (optional),
• transmits data to ZVOOK UI — a convenient interface for monitoring dozens or hundreds of sensors on an interactive map in real time.

The sensor has a high level of protection against dust, water, and mechanical impact (IP67), allowing it to be used in challenging combat and weather conditions. The system supports remote firmware updates, constantly improving the device to address new types of threats.

For the sensor to operate, it must be connected to a power source and a network (LTE or Ethernet). To activate the LTE network, a SIM card must be inserted into the sensor; a separate slot is provided for this.

The sensor is supplied as a complete kit; upon receipt, it only needs to be assembled and connected. The sensor's power consumption is 15-18 watts. 
 
With acoustic sensors, it is technically possible to build a full-fledged network to protect the line of contact, frontline cities, or logistics routes. Depending on combat conditions and terrain complexity, the network can be built using fiber optics, twisted pair, LTE, or LoRa radio channel. 
For building a reliable network, the recommended sensor placement distance is 400-600 meters from each other.

This device can be integrated into EW systems and complexes for winding fiber optic cable with concertina wire to automatically initiate launch upon FPV drone detection.
