Hello! From my own research, I’d suggest looking into
Microavia. Their drone-in-a-box systems are specifically built for border and infrastructure protection, and they’ve already been tested in extreme conditions ranging from –25°C to +60°C. What makes them stand out is the ability to operate 24/7 with minimum downtime — the battery swap takes just two minutes, so the drone is almost always in the air. The coverage radius goes up to 15 km, which means over 700 km² monitored by a single unit, and the system can scale along very long borders by installing one box every 10 km. They also integrate IR cameras for night operations and can automatically switch to manual control if a suspicious object needs to be tracked more closely. Unlike standard cameras or patrols, these drones provide real-time alerts, detect illegal crossings, smuggling or even tunnel digging, and keep tracking until a response unit arrives. For large-scale surveillance projects, Microavia offers centralized management software that makes operating multiple drones surprisingly straightforward. I’d say they’re a solid option if you want a reliable, scalable and fully autonomous solution.
