Core Strengths
High Positioning Accuracy
Up to ±0.5m localization accuracy for fast and precise alarm response.
Invisible 3D Protection
Buried deployment creates a hidden sensing field that preserves site appearance and resists tampering.
Ultra-low False Alarm Rate
0% missed alarms and <1% false alarm rate for stable perimeter protection.
Multi-scenario Adaptability
Performs reliably in complex environments with weather, animals, terrain, and vegetation interference.
How It Works
The electromagnetic sensing cable system mainly consists of an electromagnetic sensing cable controller and a pair of transmitting and receiving sensing cables. The controller generates radio frequency signals, creating an invisible three-dimensional electromagnetic field around the two cables. When an intruder enters this space, the electromagnetic energy is disturbed, triggering the controller to sound an alarm.

Frequently Asked Questions
How does the "Ultra-Array Technology" improve target detection performance?
This technology creates a one-to-one corresponding, regularly distributed array of RF signals between transmission and reception. Each unit is independent of the others, enabling multi-feature, multi-dimensional target detection of intrusion signals.
In what aspects is the system's spatial three-dimensional protection capability reflected?
The system forms a three-dimensional, invisible detection field space around the two sensing cables. Whether an intruder steps over, jumps, or attempts to dig a tunnel under the cables, the electromagnetic field energy will be disturbed, triggering an alarm.
What is the tactical significance of the system's "high concealment" in actual combat?
The detection cables can be buried underground or embedded in walls, blending completely with the environment. Intruders cannot predict the detection range, nor can they avoid the system’s detection in advance the way they could damage a physical fence.
What is the system's ability to detect fast-moving targets?
Thanks to the hardware acceleration of dedicated industrial-grade chips, the system’s signal processing can reach the microsecond level, enabling it to capture fast-moving targets (such as a sprinting intruder or a vehicle) traveling at speeds up to 108 km/h.
How does the electromagnetic sensing principle overcome false alarm interference from complex weather and vegetation?
The system achieves environmental adaptation through its algorithms. Changes in the electromagnetic field are primarily influenced by biological organisms containing a certain amount of water. Therefore, it can effectively eliminate false alarms caused by strong winds, rainfall, vegetation swaying, etc.
What support does the system's positioning accuracy provide for video linkage?
The positioning accuracy can reach up to ±0.5 meters. This high-precision data can provide extremely accurate preset position information for PTZ cameras, ensuring that the video monitoring system captures the target accurately at the first moment.
How does the "auto-calibration function" adapt to different installation environments?
After the equipment is installed, through step-by-step calibration, the main unit automatically generates the dynamic upper and lower limits of the alarm threshold based on the on-site soil medium and environmental baseline, ensuring that the alarm logic is optimized.
What are the key impacts of the cable installation technique on the detection effect?
To ensure signal consistency, the two sensing cables must be laid in parallel (recommended spacing of 80 cm), and they must avoid large, shaking metal objects (such as razor wire) to ensure the regular distribution of the electromagnetic field.
