What is the DUMBO system and what can it detect?

DUMBO is an acoustic drone detection, classification, and tracking system developed by Israeli startup Insignito. It uses multi-microphone arrays and proprietary software to detect combustion-engine drones at up to 5 km and electric drones at up to 1 km, while reducing false alarms even in urban environments.

How much funding did Insignito receive and from whom?

Insignito received a $1.5 million grant from the Israel Innovation Authority (IIA) under its SEED program. The funding will support a two-year R&D program focused on advancing the DUMBO system's technological maturity.

Where can the DUMBO system be deployed?

DUMBO's modular 30×30 cm hardware design allows it to be deployed in multiple scenarios, including soldier-portable field use, networked border surveillance using triangulation, and vehicle-mounted configurations with engine-noise filtering for detection while in motion.

Highlights

Insignito received a $1.5 million grant from the Israel Innovation Authority under the SEED program to fund a two-year DUMBO system development roadmap.

The DUMBO acoustic system can detect combustion-engine drones at up to 5 km and electric drones at up to 1 km using multi-microphone arrays.

DUMBO's compact 30×30 cm modular hardware supports soldier-portable, border surveillance, and vehicle-mounted counter-drone deployments.

The system's onboard classification engine identifies specific drone models and reduces false-alarm rates, including in dense urban environments.

Insignito positions DUMBO as a C-UAS solution for protecting strategic sites and critical infrastructure across defense and security sectors.

Israeli counter-drone technology startup Insignito has announced it has received a $1.5 million grant from the Israel Innovation Authority (IIA) to further develop its flagship product — the DUMBO acoustic drone detection, classification, and tracking system.

Two-Year R&D Program Gets Underway

In an official LinkedIn post, Insignito stated: "As part of the Innovation Authority's SEED program, we are embarking on a two-year R&D journey aimed at advancing DUMBO to a new level of technological maturity. This support will enable us to accelerate product development, address increasingly complex operational challenges, and continue positioning DUMBO as a solution for protecting strategic sites and critical infrastructure."

DUMBO System: Technical Highlights

According to Insignito's official website, the DUMBO system is equipped with advanced multi-microphone arrays and proprietary acoustic software, offering the following core capabilities:

Detection Range: Capable of detecting combustion-engine drones at distances of up to 5 km, and electric drones at up to 1 km
Intelligent Classification: An onboard engine identifies specific drone models, reduces false-alarm rates, and provides accurate azimuth estimation — remaining effective even in high-density urban environments
Modular Design: The core hardware consists of a compact 30×30 cm module that serves as a flexible platform adaptable to a wide range of deployment scenarios

Multi-Scenario Deployment Flexibility

DUMBO's modular architecture allows it to be flexibly deployed across a variety of defensive contexts:

Soldier-Portable: In field environments, individual soldiers can carry the unit for mobile personal protection
Border Surveillance: Multiple modules can be networked together to achieve precise localization through triangulation
Vehicle Integration: When mounted on vehicles, the system can activate filtering algorithms to suppress engine noise, ensuring reliable detection performance while in motion

Insignito says this modular design allows DUMBO to adapt broadly to defense and security applications, positioning it as a viable counter-UAS (C-UAS) solution for protecting critical infrastructure.
