With the expansion of digital FPV techniques, the innovation in analog FPV cameras appeared to have slowed down. Nonetheless, the discharge of the brand new Ratel Professional digicam by Caddx has sparked pleasure. Caddx claims that the Ratel Professional isn’t just one other digicam however one which delivers distinctive picture high quality each throughout the day and in low-light circumstances. This evaluate will delve into its options and evaluate its day and night time efficiency with the well-regarded Ratel 2.

Design, Construct, and Options
The Caddx Ratel Professional maintains the standard 19x19mm kind issue however distinguishes itself from the Ratel 2 with a very new design. The Professional model boasts a metallic case, enhancing sturdiness and serving as a warmth sink, albeit including an additional 4 grams—weighing in at 9.5g in comparison with the Ratel 2’s 5g.
That includes a big 1/1.8-inch picture sensor, related in dimension to the discontinued Runcam Eagle 2, the Ratel Professional guarantees superior low-light efficiency because of its capacity to seize extra mild. The digicam claims to ship excellent picture high quality with a minimal illumination requirement of 0.00001 lux.
Nonetheless, the Ratel Professional’s lens is notably longer than that of the Ratel 2, probably complicating mounting and safety. A notable downside is its 125° area of view (FOV), considerably narrower than the extra frequent 160° FOV present in trendy FPV cameras just like the Ratel 2, which gives a 165° FOV. I feel FPV drones profit from the broader area of view particularly when flying proximity and navigating although tight areas. Due to this fact this narrower FOV may restrict its enchantment to FPV drone pilots accustomed to a wider perspective.
The Ratel Professional helps switchable 4:3 and 16:9 facet ratios, switchable within the OSD menu utilizing the supplied joystick. It may be powered by a large voltage vary from 4.5V to 27V, accommodating 2S to 6S batteries direct energy.
Day Efficiency
Testing the Caddx Ratel Professional with its default settings revealed very first rate picture high quality, vibrant colours, and a large dynamic vary. The picture appeared sharper than the Ratel 2, you’ll be able to see extra element within the picture. Maybe a tiny bit oversharpened to my style as you’ll be able to see some digital artefacts within the branches, fortuitously sharpness may be adjusted within the settings. In distinction, the Ratel 2 produces a softer and fewer contrasty picture.
The lowered FOV of the Professional was instantly noticeable and considerably limiting for FPV drone flying, probably making it extra appropriate for prime altitude flying akin to fixed-wing plane. Nonetheless, the lowered “fisheye” distortion and extra correct depiction of distances had been constructive points.
Night time Efficiency
Historically, cameras just like the Runcam Night time Eagle 3 have set the usual for low-light FPV flying. They excel in the dead of night, because of their excessive sensitivity to mild. Nonetheless, their efficiency underneath the intense solar leaves a lot to be desired. That is the place the Ratel Professional steps in, promising the most effective of each worlds: vibrant colour throughout the day and excellent night time imaginative and prescient.
Because of its giant picture sensor and enhanced algorithm, the digicam’s low-light efficiency was spectacular, providing clear and crisp imagery the place the Ratel 2 struggled with graininess and noise.
Conclusion
The Caddx Ratel Professional is a step ahead in analog FPV digicam know-how, excelling in each daytime and nighttime circumstances. Nonetheless, its slim FOV might be a deal-breaker for a lot of drone pilots. Whereas it could not dethrone the Ratel 2 for FPV drone personally, it may discover its area of interest amongst pilots flying at larger altitudes or in functions the place a narrower FOV is suitable. For these searching for a flexible FPV digicam able to performing nicely day and night time, the Ratel Professional is value contemplating.
