LIVE AIR 4 SMART is a professional wireless follow focus system designed for filmmakers, content creators, and solo camera operators who need precise and responsive lens control in a compact setup. Combining a powerful SMART motor with integrated LiDAR autofocus technology, the system delivers smooth focus pulling and intelligent subject tracking for handheld, gimbal, tripod, and cinema rig workflows.
The upgraded 1.2Nm motor provides strong torque for both photo and cine lenses while maintaining a lightweight profile suitable for modern compact camera builds. With Bluetooth 5.3 connectivity and ultra-low latency communication, the LIVE AIR 4 ensures stable wireless performance with a control range of up to 100 meters.
HYBRID ZOOM LIDAR
The core philosophy of the hybrid zoom LiDAR system is to push both hardware performance and internal space utilization to the absolute limit—with zero waste and zero compromise. We concentrate all available energy into a 4° laser point, enabling scanning distances of up to 50 meters. Building on this, optical zoom technology transforms the 4° point into a 16° laser line, striking an ideal balance between visual coverage and scanning depth. For close-range scenarios, a 28° laser plane provides a much wider scanning angle, effectively covering areas like the face, hands, and upper body—enabling smoother and more comprehensive subject tracking at short distances.
Core AI Intelligence & Virtual Lens Modeling Technology
LIVE AIR 4 SMART features a dual upgrade of both hardware and intelligent algorithms. With enhanced processing power and broader compatibility, it breaks through the autofocus distance limitations of the previous-generation LiDAR motor—enabling significantly longer autofocus range and unlocking a wider variety of use cases.
The included thumb controller offers intuitive one-handed operation, making it ideal for run-and-gun filmmaking and gimbal operation. Integrated dual LiDAR modules assist with fast and accurate autofocus tracking, helping maintain sharp focus even during complex movement shots.
Whether used for independent filmmaking, commercial production, documentary work, or live content creation, the LIVE AIR 4 SMART delivers reliable wireless focus control in a portable professional package.
Built-in Gyroscope
AI-Powered Virtual Focus Tracking
Equipped with a high-performance LiDAR module and built-in gyroscope, LIVE AIR 4 SMART integrates AI-based virtual learning technology to intelligently record and learn focus paths during shooting. Using this data, the system can simulate and predict focus within a 12° tracking field of view—enabling virtual autofocus performance at distances up to 50 meters. This ensures smoother and more stable focus transitions, even with fast-moving subjects.
Once the object moves out of the scanning range, the AI’s virtual 12-degree field of view will quickly predict and lock onto the focus, preventing sudden drastic changes in focus that could damage the image.
When the subject exceeds the effective scanning range, the motor intelligently calculates based on the movement speed and autofocus behaviour it learned during previous autofocus operations (such as movement speeds and focus responses for distances like 0–5m, 5–10m, 10–15m, and 15–20m). Using this data, the system can virtually predict the subject’s movement speed and autofocus requirements between the point where the subject exceeds the scanning limit and up to 50 meters, enabling AI-driven virtual autofocus to reach a distance of 50 meters.
