Professional Wired Shock Detector with NC Output

The Dahua Shock Detector ARD416 is a wired shock detector designed to detect forced entry attempts through physical impacts, vibrations, and breaking attempts on doors, windows, and walls. This Dahua shock detector features 1 normally closed (NC) alarm output, providing early warning before intruders gain access. Moreover, it detects break-in attempts that bypass standard door contacts, including glass breaking, frame drilling, and forced prying attempts.

Early Break-In Detection

This Dahua shock detector identifies physical impacts and vibrations caused by forced entry attempts before breaches occur. Unlike door contacts that trigger only after doors open, shock detection alerts you during break-in attempts—when tools strike doors, when glass is being broken, or when frames are being pried. As a result, security personnel receive earlier warnings, enabling intervention before intruders successfully enter protected areas.

Normally Closed Alarm Output

The ARD416 provides 1 normally closed (NC) alarm output that maintains circuit continuity during normal operation. This Dahua shock detector triggers alarms when the circuit opens due to detected shocks or sensor tampering. Consequently, any attempt to disable the sensor by cutting wires or removing power also triggers alarm conditions, providing comprehensive tamper protection alongside shock detection.

Sensitive Vibration Detection

A key feature of the Dahua shock detector is its calibrated sensitivity that distinguishes between genuine break-in attempts and normal environmental vibrations. It detects forceful impacts from hammers, crowbars, and breaking tools while ignoring routine door closures, foot traffic, or passing vehicles. Therefore, it provides accurate intrusion detection without excessive false alarms from everyday building vibrations.

Professional Security Integration

The ARD416 integrates with Dahua alarm controllers including ARC2008C-V3 and ARC2016C-V3 models through standard wired connections. The NC output configuration ensures fail-safe operation where any sensor failure triggers protective alarm responses.
