Perimeter 4 Surveillance Hybrid Drone (Side View)


Extreme Endurance and RangeProprietary hybrid power system enables the Perimeter to fly for 5 hours or up to 110 miles.
Cold Temperature OperationThe Perimeter’s hybrid power system can operate in freezing conditions as low as 15°F (-10°C). Other hybrid-electric UAVs cannot operate safely in low-temperature conditions.
Highly Efficient Power Conversion> 95% shaft-to-electric conversion efficiency.
Aerodynamic ProfileEngine and fuel system are integrated into the body of the vehicle, reducing aerodynamic drag
Wide Altitude RangeElectronic fuel injection eliminates the burden of tuning the UAV for different altitudes.
Engine Vibration DampeningVibrations from engine are dampened to preserve sensor data quality
Exhaust Gas RemovalExhaust gases are routed away from the vehicle to avoid damaging payload
Engine AutostartEngine is automatically started and stopped. No pull starts or cumbersome drill starter motors.
Quick DeploymentThe Perimeter can be unboxed, assembled and flown in less than 5 minutes.
Modular Payload BayThe Perimeter is designed to accommodate payloads up to 8.8 lb (4 kg) with form factors ranging from LiDAR units, visual and thermal cameras and more.
Seamless Engine IntegrationEngine operation is fully automated, from start to finish. Just refuel and fly like a regular multirotor.
Full Engine Telemetry and ControlEngine health information is made available on the ground station. The engine can be started and stopped through the ground station.
Extremely LightweightThe Perimeter is 20% lighter than any hybrid-electric multirotor on the market today
Visible Fuel LevelsVisible fuel tanks provide quick fuel readings.
Digital Fuel Level IndicatorFuel levels are visible on the ground station.
Total Power RedundancyFully redundant power system. Can operate on battery power in case of engine failure.
Battery ProtectionG2K™ power system algorithms protect battery from charging malfunctions
Generator System MonitoringEngine health constantly monitored. Operator alerted to anomalies.
High Reliability and SafetyFuel injected engine ensures the engine runs reliably.
Smart power management system protects battery from overcharging, extends battery life, and ensures safe operation in case of an engine failure.
Engine Wear ProtectionEngine operated continuously at less than 70% of maximum power. Competitors operate at full throttle.
Long Battery ReserveLonger battery-only reserve flight time than other competing hybrid UAVs
Made in the United StatesAll software/firmware is based on open-source and compiled in house, within the United States.
EncryptionOptional AES128 encryption for data links
