Advanced Seismic and Vibration Detector with Thermal Protection
The Dahua Seismic Detector ARD421 is a wired seismic and vibration detector that detects intrusion attempts through impacts, electric drills, impact drivers, gas cutting, and explosions. This Dahua seismic detector also features thermal monitoring that triggers alarms when temperature rises 10°C within 30 seconds. Moreover, it provides comprehensive security against sophisticated break-in methods including cutting, drilling, and thermal attacks on safes, vaults, and high-security perimeters.
Multi-Threat Vibration Detection
This Dahua seismic detector identifies diverse intrusion methods through advanced vibration analysis. It detects impacts from hammers and crowbars, high-frequency vibrations from electric drills and impact drivers, specific signatures from gas cutting torches, and shockwaves from explosions. As a result, it provides protection against professional burglary techniques that standard sensors miss, making it essential for high-value asset protection.
Rapid Temperature Rise Detection
The ARD421 includes thermal monitoring that detects 10°C temperature increases within 30 seconds. This Dahua seismic detector alerts when cutting torches, thermal lances, or explosive devices create rapid heat signatures during break-in attempts. Consequently, it identifies thermal attack methods used against safes, vaults, and reinforced barriers before breaches occur.
Professional High-Security Protection
A key feature of the Dahua seismic detector is its ability to detect sophisticated attack methods beyond simple forced entry. Professional burglars using power tools, cutting equipment, or explosives generate distinctive vibration and thermal patterns. Therefore, this sensor provides enterprise-grade protection for bank vaults, jewelry stores, data centers, and facilities storing high-value assets.
Critical Infrastructure Security
The ARD421 integrates with Dahua alarm controllers including ARC2008C-V3 and ARC2016C-V3 models. Its dual detection capabilities—vibration analysis and thermal monitoring—provide comprehensive protection against both mechanical and thermal intrusion methods.
