«Sigma-4» Mission Payload
A versatile multi-sensor payload (electro-optical system) on a three-axis gyro-stabilized gimbal. Integrates dual cameras, a thermal imager, a laser rangefinder and an embedded AI module.
«Sigma-4» Mission Payload
low weight and compact size enable its use even on lightweight drones.
Key Benefits
Rugged, Compact Enclosure
A lightweight (380g) aviation-grade aluminum housing with IP43 rating offers protection against vibration, moisture and operates reliably in temperatures from –20°C to +55°C
AI-Powered Detection & Tracking
A 2 TOPS AI module detects, tracks, and geo-locates targets at ranges up to 1,700 meters, with automatic re-acquisition after brief target loss
Dual-Camera Visual Surveillance
Features two optical cameras (telephoto and wide-angle) for high-quality visual monitoring across both near and far distances
Easy Integration & Broad Compatibility
Universal interfaces (S.BUS, UART TTL, Ethernet) and a wide input voltage range (14-60 V DC) enable installation on virtually any modern drone platform
