A wireless sensor array for detecting active tapping and vibration signals transmitted through rubble, concrete, steel and other solid rescue-site media.
Core Capabilities
A wireless vibration sensor array helps rescue teams compare active tapping signals, narrow the likely survivor area and establish two-way communication.
Multiple wireless sensors compare active tapping and vibration signals across a rescue search zone.
The Android terminal displays relative signal strength, battery status and filter settings for live search decisions.
The 8-inch control terminal displays sensor vibration levels, battery status, calibration and stereo channels on one screen.
Compact sensors are designed for rescue-site deployment with sealed protection and a wide operating range.
An intercom probe and pickup support communication after the team narrows the strongest signal zone.
The field-ready kit combines sensors, terminal, intercom probe, antennas, chargers and protective case for deployment.
Include your sensor quantity, destination country, training needs and delivery deadline.
Applications
Applicable to municipal fire services, industrial emergency teams, hazardous-materials sites, and wildfire response units, subject to operational requirements.
Use wireless sensors after earthquakes, building collapses, landslides and other rescue incidents where visibility is blocked.
Place sensors on rigid structural media and compare signal levels to prioritize the strongest search zone.
Use for tunnel, mine and flood rescue where vibration signals can be transmitted through suitable structural media.
Operational Scenario
The scenario below illustrates a microseismic sensor deployment. Actual results vary with medium, noise, contact and tapping strength.
Situation
A collapse leaves survivors beneath rubble where visibility is blocked and a controlled active signal can travel through rigid media.
Potential use
A team can place 2-10 sensors, calibrate the array, compare live signal levels and use the intercom channel after narrowing the search zone.
Decision support
Findings may inform search priorities and structural risk discussions under the incident commander's procedures. Outcomes depend on conditions, training, and additional equipment.

Frequently Asked Questions
Answers to common questions from fire-service procurement teams and end users. Confirm all commercial and technical terms with the supplier.
The system requires an active tapping or scratching signal; it cannot reliably identify an unconscious person who produces no active signal.
The system provides 10 h or more of operation. Actual performance varies with sensor use, wireless conditions and deployment environment.
The documented standard configuration supports 2-10 microseismic sensors. Confirm the ordered quantity and final accessory list with the supplier.
Contact the supplier with your organization, intended use, quantities, and delivery market. Ask about demonstration availability, a compliance matrix, test reports, and manufacturer authorization where required; availability and terms must be confirmed in writing.
Request written warranty coverage, service turnaround, spare-parts availability, and recommended calibration intervals in the quotation. Inspection and recalibration may be advisable after severe heat exposure or impact; service terms depend on the purchase agreement.
Supplier Support
Discuss use cases, operating conditions, and specification requirements with the supplier's technical team.
