Perun Eye

Perun Eye - FPV Drone Detector

PERUN EYE is a portable electronic intelligence device designed for real-time detection and interception of analog FPV drone signals. It is a compact, single-operator tool that provides immediate warning of UAV activity — no configuration required.

What is PERUN EYE?

PERUN EYE is a handheld RF scanning and video interception device built for field use. It continuously monitors the radio spectrum for FPV analog video signals, alerts the operator upon detection, and intercepts the drone operator's live video feed directly on-screen. Operating entirely in passive mode, PERUN EYE remains undetectable to the enemy while delivering reliable situational awareness.

How PERUN EYE works

• Immediately after power-on, the device begins continuously scanning the RF spectrum for FPV signals.

• Detected signals are analyzed for signal strength, modulation type, and video content.

• The secondary screen displays signal levels and the count of active emissions. When a valid FPV video signal is identified, the primary screen replicates the intercepted live video feed.

• Simultaneous audio and visual alerts notify the operator of UAV presence.

Key Features

Smart RF filtering Distinguishes FPV video signals from background RF noise using power threshold and video modulation verification, reducing false alarms.

Direction finding support Compatible with both omnidirectional antennas for 360° area scanning and directional antennas for extended-range detection and precise target bearing. Antenna type can be selected based on mission requirements.

Adjustable RSSI detection threshold Detection sensitivity is fully user-configurable, allowing the operator to set the appropriate engagement range and filter out irrelevant distant signals.

Dual-display visualization The secondary screen shows signal strength and the number of detected signals. The primary screen displays the intercepted live FPV video feed, replicating what the drone operator sees.

Light and sound alerts When a UAV is detected, the device triggers a simultaneous audible beeper alert and an on-screen visual notification.

Extended field operation The device uses easily replaceable battery packs. Carrying spare charged sets allows the operator to hot-swap batteries in the field and resume scanning immediately, enabling continuous long-duration deployment without access to a power source.

USB-C pass-through power PERUN EYE can be powered directly via USB-C while in operation, making it suitable for fixed positions or vehicle-mounted deployments that require sustained uptime.

Compact and portable The lightweight, minimal enclosure is designed for practical field use — easy to carry, conceal, and operate single-handedly, reducing operator fatigue during extended missions.

Ongoing software updates The operating system receives continuous improvements developed in close collaboration with end-user feedback, ensuring the device evolves with operational needs.

Current Status: Prototype — Early Access Available

PERUN EYE is currently in active development. The device available for purchase today is Version 1 — a fully functional prototype that has been tested in field conditions and is ready for operational use.

What's coming in Version 2

Version 2 is currently in development and will bring meaningful hardware improvements based on field feedback:

• Support for the 1.2 GHz frequency band, expanding detection coverage alongside the existing 5.8 GHz range.

• An improved casing with enhanced durability and ergonomics.

Early access offer

Customers who purchase Version 1 today will receive a free hardware replacement when Version 2 becomes available. In the meantime, Version 1 units will continue to receive periodic firmware updates, improving performance, detection algorithms, and stability throughout the lifetime of the device.

This is an opportunity to get PERUN EYE into your hands now — and grow with the product as it develops.
