The Caddx Eclipse 640 thermal camera is a compact thermal imaging module for FPV drones, built on an uncooled vanadium oxide detector with a resolution of 640×512 pixels. The camera is designed to produce a clear image in complete darkness, smoke, or fog, when conventional optics stop being effective. Its compact size and low weight allow the module to be easily integrated into most FPV platforms without significantly affecting the aircraft's overall mass.
🫡 We are a team of veterans
We regard the Caddx Eclipse 640 as a tool that significantly expands FPV reconnaissance capabilities at night. Detecting the thermal signature of a person or vehicle where a conventional camera shows only solid darkness often determines the outcome of a surveillance mission. The 640×512 resolution combined with a wide 8–14 μm wavelength range provides clear detail of thermal contours even at considerable distance. Low signal latency is critical for FPV piloting — this module delivers a level acceptable for confident real-time aircraft control.

Comment / comments
The key advantage of the Caddx Eclipse 640 is its combination of high 640×512 resolution with a low NETD rating (up to 40 mK), providing clear detail of thermal contours even with a minor temperature difference between the object and background. This is critical for identifying a person or vehicle at a distance when thermal contrast is low. The AI-based image enhancement function further improves image clarity compared to a standard unprocessed thermal signal.
The compact 27×37×40 mm dimensions and weight of only 60.5 g allow the module to be mounted on virtually any FPV platform without significantly burdening the power system. The modular design, with a separate thermal sensor unit and main processing module, simplifies mounting and camera placement for a specific aircraft configuration.
🎯 Who it is suitable for
Military FPV drone operators conducting reconnaissance and strike missions at night gain the ability to detect thermal signatures of people and vehicles where conventional optics are completely ineffective. Low signal latency allows confident real-time aircraft control even during complex maneuvering. The module's compact size and low weight allow the thermal camera to be mounted on lightweight strike FPV platforms without significantly affecting flight characteristics. The wide operating temperature range ensures stable camera performance in field conditions regardless of the season.
Search and rescue units using FPV drones to locate victims in difficult visibility conditions can use this camera to detect the thermal contours of people under partial vegetation cover, in smoke-filled environments, or at night, when search time is critical to the operation's outcome.
Industrial monitoring and inspection operators using FPV platforms to survey hard-to-reach objects can use the thermal camera to detect structural temperature anomalies, heat leaks, or equipment overheating without requiring a stationary thermal imaging system.
FPV pilots building custom reconnaissance drones get a compact, lightweight thermal module with low latency that integrates well into various builds thanks to its small size and flexible modular connection.
