Core Product Advantages & Functional Features
Full-Spectrum Blind-Free Precision Detection
The VS-F8 supports continuous spectrum scanning from 100 MHz to 8000 MHz with a 1 MHz fine tuning step, eliminating signal coverage dead zones across all common drone operating frequency bands. While scanning the full spectrum, the device automatically captures real-time analog FPV video streams, and simultaneously displays visualized core threat data on its built-in screen, including drone classification, exact signal frequency value, and real-time signal strength grading. Advanced signal filtering algorithms suppress irrelevant background RF noise, delivering a drastically reduced false alarm rate compared to conventional narrow-band detectors.
2)Universal Compatibility with Mainstream UAV Platforms
The preloaded signal signature library fully recognizes all mass-market commercial drone models from DJI and Autel, alongside nearly all DIY FPV racing drones transmitting analog video. The device automatically labels identified target types on the alarm list screen, allowing operators to instantly distinguish consumer-grade drones and illegal racing UAVs without extra configuration.
3)Accurate Signal Direction-Finding & Target Locating
Users can upgrade the system with an optional high-gain directional antenna to unlock professional bearing-locating functionality. By slowly rotating the handheld unit and observing real-time fluctuations of the signal strength figure displayed on screen, field staff can rapidly lock the exact direction of the drone signal source, greatly boosting target capture efficiency and positioning accuracy during on-site patrol missions.
4)Dual-Mode Real-Time FPV Video Interception
The VS-F8 integrates native analog video decoding hardware to extract live first-person view footage transmitted by FPV drones within the full 100 MHz–8 GHz band. Two independent display workflows are available for operational flexibility: operators can directly view intercepted video on the built-in main screen of the handheld unit, or connect an optional external HD monitor via the proprietary magnetic interface to broadcast live footage to command teams for joint situational awareness. A short delay of 0–10 seconds for video rendering is normal operation when locking onto new analog signals.
5)Seamless Integration with Counter-UAV Jammer Systems
The unique magnetic external interface enables instant physical linkage with backpack-type UAV jamming equipment. Once a drone signal is detected and locked, the VS-F8 outputs a trigger signal to activate paired countermeasure hardware, forming a complete integrated “detect-locate-neutralize” airspace defense workflow that drastically improves operational response efficiency for professional security teams.
6)Rugged All-Weather Industrial Design
Engineered for long-duration outdoor field use, the VS-F8 maintains flawless stable operation across an extreme working temperature range of -20 °C to +60 °C, with safe storage supported between -40 °C and +85 °C. The unit carries an official IP54 ingress protection rating, with a reinforced housing that effectively blocks dust accumulation and accidental water splashes, enabling reliable deployment in rainy, dusty, high-temperature or cold open-air environments.
7)High-Speed Charging & Long Continuous Runtime
The device supports 35W Type-C fast charging technology; a fully drained battery reaches 100% capacity in only one hour to minimize downtime between shifts. It comes standard with a swappable 2900 mAh high-performance lithium polymer battery, delivering up to 7 hours of uninterrupted continuous detection for all-day field patrols without power supply access.
8)Wireless Bluetooth Data Synchronization
Built-in Bluetooth communication modules transmit real-time detection logs, spectrum data, and drone alert records to the dedicated DX-SMART mobile application on compatible smartphones or tablets. Remote command staff can monitor field detection data wirelessly, simplifying cross-team coordination and centralized airspace monitoring management.
9)Comprehensive Built-In Auxiliary Functions
The VS-F8 includes a full set of customizable system settings accessible via physical button operation: multi-language switching, date and time calibration, screen and key backlight brightness adjustment, vibration alert toggle, power-saving eco mode, local alarm data logging and erasure, fan cooling switch control, and firmware upgrade capability via the magnetic data cable. All alarm events are automatically stored in onboard storage for post-mission review and evidence archiving. Dual alert feedback modes (audible sound and built-in vibration) guarantee operators never miss drone intrusion warnings even in noisy outdoor environments.
Technical Performance Specifications
The VS-F8 receives radio signals across a continuous 100 MHz to 8000 MHz frequency band, covering all standard control and video transmission bands for commercial and FPV drones. It supports identification of two primary signal categories: OFDM high-definition digital video transmission from branded consumer drones, and FM analog video signals from custom racing drones.
The nominal effective detection distance reaches a minimum of 1 kilometer under open unobstructed conditions; actual detection range will vary depending on the drone’s transmission power and operating frequency band, and the optional directional antenna can further extend maximum detectable distance. The device triggers both sound and vibration alerts upon detecting drone signals, and continuously records all alarm data to internal storage for later review.
All external connection relies on the proprietary magnetic cable interface, which serves three key purposes: firmware upgrade via computer connection, external video display output, and electrical trigger signal output for jamming countermeasure equipment. Power is supplied via a removable lithium battery pack, with Type-C fast charging compatibility supported on both the battery and main unit.
The handheld main body (excluding antennas) measures approximately 164 mm in length, 44 mm in width and 68 mm in thickness, with a total weight of roughly 580 grams when fitted with the standard battery and dual antennas. Power activation requires a 3-second long press of the dedicated power button, while a 5-second long press initiates full shutdown. All system navigation and parameter adjustments are completed via physical directional and function buttons on the front panel, including volume control, screen backlight adjustment, and real-time drone threat data browsing.
For environmental adaptability, the unit operates reliably from -20 °C to +60 °C, while safe long-term storage is permitted between -40 °C and +85 °C, with IP54 dust and splash resistance certification for the outer casing.
