Sony FCB camera block
During the Shenzhen International Unmanned Aerial Vehicle Exhibition in May 2025, Xuanzhan Technology, the official authorized distributor of SONY (China) and the China launch center for the FCB series cameras, made its first public appearance with the SONY dToF sensor AS-DT1. Senior leaders of SONY Group visited the Xuanzhan Technology booth in person to provide on-site guidance and had in-depth exchanges with the team on the details of the technical demonstration. With its breakthrough dToF 3D perception capability, SONY AS-DT1 has drawn high attention from the industry on site.
From October 28th to 31st, 2025, SONY AS-DT1 once again participated in the CPSE, presenting itself AS the world’s smallest and lightest lidar depth sensor, bringing breakthrough precise obstacle avoidance capabilities to mobile security drones.
I. Tiny Body, Huge Breakthrough: Redefining the perception Standards of Security Drones
The SONY AS-DT1 measures only 29mm × 29mm × 31mm and weighs just 50 grams. This ultimate miniaturized design makes it an ideal choice for mobile security drones where space and weight are limited. Within its lightweight body lies a powerful environmental perception capability.
This sensor adopts dToF (Direct Time-of-Flight) technology and combines a single-photon avalanche diode (SPAD) sensor, capable of achieving high-precision measurements with an error of less than ±5 centimeters within a distance of 10 meters. This means that security drones can accurately and in real time perceive surrounding obstacles in complex environments, significantly enhancing flight safety and stability.
Ii. Strong performance, fearless of challenges: Reliable performance in complex environments
The SONY AS-DT1 is equally impressive in terms of performance. In indoor environments, its ranging distance can reach up to 40 meters, and even under strong outdoor light (100,000 lux), it can achieve an accurate ranging of 20 meters. This feature enables security drones to maintain reliable environmental perception capabilities whether in dim indoor scenes or outdoor environments exposed to direct sunlight.
It is worth mentioning that the SONY AS-DT1 can effectively detect low-contrast and low-reflectivity objects, such AS glass doors, transparent partitions and other obstacles that are difficult for traditional sensors to identify. This breakthrough capability has greatly expanded the application scope of drones in complex security scenarios.
Iii. Security Applications: Precise Obstacle Avoidance Empowers Diverse Scenarios
In the field of infrastructure inspection, security drones equipped with AS-DT1 can conduct efficient inspections of key facilities such AS Bridges, highways, and DAMS. Sensors can accurately identify minute defects such as cracks and wear, and at the same time achieve precise obstacle avoidance and stable positioning, ensuring the safety and efficiency of inspection operations.
For emergency rescue scenarios, the powerful environmental adaptability of SONY AS-DT1 enables the drone to maintain reliable perception in low visibility conditions such AS thick smoke and haze, providing accurate environmental information for rescue personnel while ensuring the safe flight of the drone itself.
In the field of security monitoring, this dToF sensor AS-DT1 supports multi-point ranging and can simultaneously capture three-dimensional data of length, width and depth, achieving more accurate environmental modeling and obstacle avoidance decision-making. This feature holds significant value for application scenarios such as regional monitoring and perimeter protection.
Iv. Technology Empowerment: Creating the Next Generation of Intelligent Security Drones
The SONY AS-DT1 adopts dToF technology, which calculates the target distance by emitting pulsed light and measuring the round-trip time difference, achieving direct and precise distance measurement. Combined with the high sensitivity of the SPAD sensor, even single-photon signals can be effectively detected, greatly enhancing the environmental adaptability of the sensor.
The sensor’s robust aluminum alloy housing design not only ensures lightweight characteristics but also offers excellent durability, enabling it to adapt to various complex security operation environments. This design concept enables SONY AS-DT1 to operate stably in outdoor security scenarios for a long time, significantly reducing the maintenance requirements of the equipment.
V. Future Outlook: A New Chapter in Intelligent Security
The launch of SONY’s AS-DT1 has injected new vitality into the development of mobile security drones. Its features of miniaturization, high precision and strong adaptability are driving security drones to develop in a more intelligent and reliable direction. With the rapid development of the low-altitude economy, AS-DT1 is expected to play a greater role in urban management, public security, emergency rescue and other fields, providing technical support for building a safer and smarter social environment.
Welcome to the Xuanzhan Technology booth at the 2025 CPSE to experience firsthand how SONY AS-DT1 emempowerment mobile security drones and jointly create a new future for intelligent security!
