Since detector types vary widely in cost, understanding the price range and its influencing factors is essential for making smart, cost-effective choices.
This article will analyze the price range of mainstream drone detectors, focusing on drone LiDAR sensors, and recommending affordable products.
Radar detectors use radio waves to detect objects by analyzing the reflected waves to calculate their position, speed, and other information. They possess a long detection range, relatively precise positioning, and are less affected by weather. However, they are typically bulky, have high power consumption, and are not suitable for small drones or consumer applications.
The price of a radar detector varies significantly based on its performance and features. The price usually increases proportionally with extended detection capabilities and enhanced system reliability.
RF detectors are passive devices that don't actively transmit signals. Instead, they work by monitoring the radio communication signals between a drone and its controller. Each drone model has a unique signal signature, which the RF detector identifies by matching it against a built-in signal database.
This approach offers several benefits, including affordability, compact size, and minimal energy requirements. They can also detect a drone's presence from a distance and may even be able to locate the operator.
Basic models offer reliable detection range and basic real-time spectrum analysis, with prices around a few hundred dollars. High-end models, however, feature AI-powered signal identification, adjustable filtering, and extended range for professional environments, which can cost several thousand dollars.
Acoustic detectors on drones employ a high-sensitivity microphone array to capture distinct sound frequencies from the surrounding environment (e.g., machinery, vehicles, or wildlife). As an onboard sensing tool, they are one of the most affordable detection technologies available. Simple single-point acoustic sensors or DIY kits for drones may cost just a few dozen to a few hundred dollars, while integrated professional systems with multi-microphone arrays and advanced signal processing algorithms typically reach several thousand dollars.
These drone detectors adopt dual-spectrum sensing technologies for environmental perception and mission execution. Visible light cameras record high-definition color imaging, which permits operators to visually identify targets and terrain features. Simultaneously, thermal imaging sensors generate visuals based on temperature profiles. However, both technologies are susceptible to false positives from objects like birds and balloons.
Visible Light Cameras: Prices are relatively low, ranging from a few hundred to several thousand dollars, depending on the resolution and zoom capabilities.
Thermal Imagers: These are notably more expensive. Entry-level products typically cost several thousand dollars, while professional-grade thermal imagers for long-range detection and high-resolution imaging can exceed tens of thousands of dollars.
LiDAR sensors operate by emitting pulsed laser beams to gauge distance, By returning precise distance values at high frequencies, the drone can maintain a distance from the ground or obstacles to avoid collisions and losses.
Compared to other types of drone detectors, drone LiDAR sensors have the advantages of high detection accuracy and strong anti-interference capabilities, performing well in complex environments.
The cost of a LiDAR sensor has the widest range of all detector types. Among all models available on the market, Benewake offers cost-effective LiDAR solutions that are more affordable than competing brands. For example, our TF-Luna and TF02-Pro, designed for drone obstacle avoidance or ranging, are very reasonably priced.
The detection range is a primary cost driver for a drone LiDAR sensor. Longer operational distances demand progressively higher performance from core components, which in turn drives up the price.
Short-range variants have relatively modest requirements for laser emitter power and receiver sensitivity. This results in lower manufacturing costs and more accessible pricing.
In contrast, long-range LiDAR requires more powerful laser sources, higher-precision optical components, and more sensitive photodetectors. Additionally, their hardware structure and signal processing algorithms are more complex, which directly pushes up the overall cost.
Accuracy is a core performance metric for a drone LiDAR sensor. High-accuracy LiDAR sensors can output reliable distance measurements with minimal error. Achieving this level of precision requires more sophisticated calibration, advanced signal processing chips, and a more stable optical system, which leads to higher costs and prices.
Certain brands with deep expertise and strong market recognition in the LiDAR field often come with a brand premium. This premium isn't just for product development; it also covers the brand's investment in technical support, software ecosystems, data processing capabilities, and overall system reliability. For example, some high-end brands that provide complete hardware and software solutions for professional users naturally have a higher price point.
A drone LiDAR sensor capable of withstanding high temperatures, low temperatures, humidity, and strong vibrations requires rigorous qualification testing and high IP-rated enclosures. Their durable shells, internal seals, and heat dissipation systems all increase manufacturing costs.
In addition, some sensors also need to be equipped with complex anti-interference algorithms and heating and defogging functions, which introduce additional engineering and manufacturing expenses.
At Benewake, we are committed to developing high-value LiDAR solutions through application-specific optimization and streamlined manufacturing processes. Below are three of our most cost-competitive LiDAR sensors for drone applications:
Our TF-Luna LiDAR sensordelivers precise single-point ranging capabilities across 0.2–8 meters with 1cm resolution, employing adaptive algorithms and configurable parameters to maintain accuracy in diverse operating conditions. Its exceptionally lightweight design, at under 5 grams, and ultra-low power consumption, below 0.35W, can significantly boost drone performance in applications where payload constraints and power efficiency are critical.
The TFS20-L, comprising a high-sensitivity, infrared-enhanced SPAD sensor, is a fully integrated, single-channel dToF miniature ranging module that facilitates a measurement range of up to 20 meters.
Furthermore, it also boasts strong ambient light immunity of up to 15 meters at 100 KLux and includes a reflectance correction function.
Additionally, this drone LiDAR operates on a single 3.3V power supply and has a built-in temperature compensation function. It supports I²C and UART interfaces, making it easy to integrate and use.
The TFA300-L functions at a default frequency of 1 to 1,000 Hz, with an ultra-high frequency mode that can be adjusted up to 10,000 Hz. This allows for faster obstacle detection and quicker distance updates, giving drones a longer reaction time.
Using an industry-standard JST GH connector, the drone LiDAR sensor can be directly connected to a flight control platform without the need for an adapter.
Equipped with an SDK that supports the DroneCAN protocol, it presents plug-and-play compatibility with mainstream flight controllers. This substantially reduces development time and lowers deployment costs.
At present, over one million Benewake LiDAR sensors have been deployed globally, supporting a wide range of drone applications from obstacle avoidance to precise distance measurement. By continuously optimizing performance and streamlining manufacturing, we are dedicated to making high-performance, cost-effective drone LiDAR sensors accessible to developers, integrators, and innovators across industries.
