PROXYSearch and Rescue Drone Support
In search and rescue (SAR) operations, every minute counts. A person lost in the Fagaras Mountains, a child missing in the Somes River flood zone, an elderly person disoriented in the forests of Maramures — in all these scenarios, the ability to rapidly scan large areas can mean the difference between life and death.
Drones equipped with thermal and high-resolution optical cameras transform SAR operations. Where a ground search team covers 1-2 km² per hour in difficult terrain, a drone scans 10-15 km² in the same time. The thermal camera detects the human body's heat signature at altitudes of 50-100 m, even at night, through dense vegetation, or in fog.
How It Works
- SAR alert through the platform. The competent authority (ISU, Mountain Rescue, Police) or a mission coordinator launches an aerial support request on ProxyDrone at maximum priority. The search zone, last known location of the person, and terrain conditions are specified.
- Rapid mobilization. The platform identifies SAR-certified operators near the search zone. Target time from alert to takeoff is under 60 minutes. The operator travels to the mission command post.
- Systematic scanning flight pattern. The drone executes a predefined search pattern (parallel, expanding, or sectoral) over the designated area. The thermal camera runs continuously while the operator monitors the live feed for suspicious thermal signatures.
- Detection and team guidance. Upon detecting a thermal signature consistent with a person, the operator marks the exact GPS coordinates and transmits the location to ground teams in real time. The drone stays overhead for guidance until visual contact is made.
Technical Capabilities of SAR Drones
Thermal Camera (FLIR / DJI Zenmuse H20T)
The thermal sensor detects infrared radiation emitted by the human body (surface temperature ~32-35°C vs. surrounding environment at 5-20°C). The temperature difference creates a clear contrast on the thermal image. Modern thermal resolution (640×512 pixels) allows person detection at flight altitudes up to 120 m.
Night Operations
The thermal camera does not depend on visible light. Detection performance is actually superior at night, when thermal contrast between the person and the environment is at its peak (lower ambient temperature). Drones equipped with anti-collision systems can operate safely at night.

Comparison: Drone vs. Ground Teams vs. Helicopter
| Criterion | SAR Drone | Ground Teams | Helicopter |
|---|---|---|---|
| Hourly cost | ~350 RON/ha | Variable (volunteers + logistics) | 3,000-8,000 RON/hour |
| Mobilization time | 30-60 min | 1-3 hours | 1-4 hours (if available) |
| Night operation | Yes — superior at night (thermal) | Very limited and risky | Limited — requires NVG |
| Rugged mountain terrain | Excellent — flies over any relief | Slow, risk of rescuer injury | Limited by wind and visibility |
| Dense forest | Thermal camera partially penetrates canopy | Very slow, reduced visibility | Ineffective — cannot see through trees |
| Noise | Minimal — allows hearing calls for help | N/A | Loud — drowns out calls for help |
Analysis: The Time Factor in SAR Operations
International studies show that the survival probability of a lost person in a mountain environment drops dramatically in the first 24-48 hours, especially at night and in cold conditions. In Romania, with a mountain thermal range of 15-20°C between day and night, hypothermia can set in within 3-6 hours of nocturnal exposure at altitudes above 1,500 m.
Drones drastically reduce the scanning time for a given zone. A typical scenario: person missing on a mountain trail, last known location at 1,800 m elevation, estimated search area of 8 km². A team of 10 volunteers covers this area in 6-8 hours on rugged terrain. A drone with a thermal camera scans the same zone in under 45 minutes.
The drone does not replace ground teams — it complements them. It identifies the probable location of the person and guides rescuers directly, eliminating hours of "blind" searching.
Use Cases
Lost persons in mountains
Romania has 15 mountain ranges with peaks above 2,000 m. Mountain Rescue (Salvamont) responds to over 3,000 missions per year. Thermal drones are effective at identifying lost hikers at night, on exposed ridges, or in low-visibility conditions (fog, low clouds). Flight endurance of 40-55 minutes covers large search areas in successive sessions.
Missing persons in flood zones
During floods, people may be isolated on land islands, rooftops, or elevated areas. The drone provides a complete aerial perspective and rapidly identifies points where people are stranded, enabling precise routing of rescue boats.
Search in extensive forest areas
Disoriented elderly persons, lost children, individuals with mental health conditions — in forest environments, ground teams advance extremely slowly. The drone's thermal camera detects human presence through vegetation under favorable conditions (canopy below 80%, no heavy rain).
Support for alpine interventions
Aerial reconnaissance of the access route for rescuers, assessment of trail conditions (snow, ice, avalanches), exact victim localization for evacuation planning — all are possible with a drone before exposing the rescue team to risk.
Why ProxyDrone
The ProxyDrone platform maintains a network of verified operators with thermal equipment and SAR experience. Upon a search and rescue alert, the system automatically identifies qualified operators within range. Coordination happens in real time through the platform, with video feed transmitted directly to the command post.
No hidden costs. The price includes operator travel, flight, live monitoring, and transmission of detection coordinates. Payment is processed quickly through the platform, without bureaucracy.
Frequently Asked Questions
How much does a search and rescue drone mission cost?
The rate is approximately 350 RON/hour, including the operator, thermal equipment, and travel. By comparison, one hour of helicopter time costs 3,000-8,000 RON.
Can the drone fly at night?
Yes, and performance is actually superior at night. The thermal camera detects human heat signatures better when ambient temperature is lower, maximizing thermal contrast.
Who can request aerial SAR support?
ISU, Mountain Rescue (Salvamont), Police, Gendarmerie, or any authorized mission coordinator. The platform gives maximum priority to SAR requests with mobilization in under 60 minutes.
What happens if the person is in dense forest?
The thermal camera partially penetrates the forest canopy. Detection is effective when canopy cover is below 80% and there is no heavy rain. The drone complements ground teams, it does not replace them.
