Contractors Online offers an integrated defense system against small drones that can automatically detect and effectively neutralize UAVs!
System for protecting objects from UAVs
Every year, the number of incidents involving unmanned aerial vehicles (UAVs) is growing. Today, drones can pose a serious threat to energy facilities, military installations, industrial enterprises, transportation, and critical infrastructure. Their use for reconnaissance, sabotage, and attack purposes requires facility owners to implement comprehensive UAV detection and suppression systems.

Key elements of the System
  • Radio frequency detector
    with UAV detection (identification) and positioning function. UAV detection range up to 5 km!
  • Combined optoelectronic device on a rotating platform
    for optoelectronic detection (daytime, nighttime), tracking, and identification of airborne objects at a range of up to 1,500 m.
  • Solid-state radar detector (RLS)
    with UAV detection function
    360 x 180 degree control zone, instrumental detection and tracking range of aircraft with minimum RCS (0.01 sq. m) up to 1500 m.
  • System control equipment
    • intelligent controller
    • network archive server
    • operator workstation equipment

Advantages of our System

  • Combined detection of UAVs within a radius of 3-5 km: radio frequency, radar, and optical-electronic
  • Suppression of control and telemetry channels: targeted impact without excessive power
  • The use of a high-precision, high-speed rotating platform allows the camera to be aimed and tracked, including high-speed, small-sized targets (FPV drones)
  • Integration with additional solutions (thermal imaging, intelligent suppression) and other security systems.
  • Neural network target identification: filtering out false objects (e.g., birds)
  • Tracking and escorting targets: even when the drone is radio silent
  • Scalability: the ability to protect both small and distributed objects
  • The manufacturing time for the system is from 2 months
Intelligent rotating surveillance and counter-UAV camera
The central element of the system's visual control is an IP video surveillance camera with built-in neural network video analytics, equipped with a swivel mechanism.
Technical specifications:
  • Resolution: up to 2560x1440
  • Field of view: from 61.8° to 1.86°
  • Rotation: up to 360° horizontally, from minus 90° to plus 45° vertically
  • Rotation speed: from 0.01 to 120 degrees/sec horizontally, from 0.03 to 40 degrees/sec vertically
  • Laser IR illumination range: with a wide illumination angle ≥300m, with a narrow illumination angle ≥1000m
  • Protection rating: IP66
  • Built-in windshield wiper
  • Video analytics: object detection, automatic tracking, false target exclusion (e.g., birds)
  • Integration with the Filin thermal imaging locator manufactured by ELVIS-Neotek

Integration with radar systems:
  • RADAR-IQ manufactured by Diagnostika-M
  • Orwell-R manufactured by ELVIS-Neotek
  • Neva manufactured by MKiS
  • MRS manufactured by NPF Mikran
Acoustic detection and direction finding devices
Acoustic reconnaissance is an effective tool for early detection of drones, especially in complex radio-electronic environments or when UAVs are flying in radio silence mode.

Acoustic sensors are capable of detecting noise from engines and airflows, providing an additional layer of protection for facilities.
Advantages of acoustic devices:
  • All-weather capability
  • Effective when drones are in radio silence mode
  • Easy to deploy and use
  • Increase system reliability through multi-sensor capabilities

Automated vehicle underbody inspection system
The underbody of a vehicle is one of the most vulnerable areas for concealing explosives, weapons, and contraband. The use of mirrors is morally and technologically outdated: it is ineffective, subject to human error, and time-consuming. Modern solutions require automation and personnel safety.
Our solution
The remote vehicle underbody inspection system from Contractors Online is a set of hardware and software tools that enable fast and reliable monitoring of vehicles at entrances, checkpoints, and secure areas!
Wide range of applications
Detection of contraband, explosives, weapons, inspection of vehicle chassis for damage
Compact size and easy installation
High-tech scanning
  • High-resolution machine vision camera with high frame rate
  • 12-bit HDR processing and automatic illumination from 12 LEDs ensure a clear image in any lighting conditions
  • Vehicles can pass at variable speeds and stop on the platform without loss of quality
  • Inspection speed up to 30 km/h with ground clearance up to 1000 mm
  • Patented distortion compensation and composite image formation technologies are used
