Application Scenarios

Where HZ-SN-16 acoustic sphere linked sonar is used

HZ-SN-16 adds auditory perception to security systems. It detects abnormal sounds in a 360° area, outputs sound source direction, and links PTZ cameras for rapid visual verification. It is suitable for drone acoustic detection, gunshot and explosion localization, perimeter surveillance and critical infrastructure security.

One air sonar array, four sound-triggered security applications.

The 16-element array listens for trained acoustic events, locates the sound source, and turns compatible ONVIF Speed Dome Cameras toward the target for confirmation and evidence capture.

FAQ

HZ-SN-16 Acoustic Sphere Linked Sonar FAQ

Common questions about drone acoustic detection, abnormal sound localization, gunshot and explosion direction finding, ONVIF PTZ camera linkage and audio-triggered security monitoring.

What is HZ-SN-16 used for?
HZ-SN-16 is used for abnormal sound detection, sound source localization and PTZ camera linkage. Typical applications include drone acoustic detection, gunshot and explosion localization, perimeter security, public safety, industrial park monitoring and critical infrastructure protection.
How does HZ-SN-16 locate a sound source?
The system uses a 16-element microphone array to capture sound signals from different directions. By analyzing the time and phase differences between array elements, it estimates the sound source direction and outputs azimuth and pitch angle information.
Can HZ-SN-16 be used for drone detection?
Yes. HZ-SN-16 can be used for low-altitude drone acoustic detection when drone sound samples are collected and trained in advance. After a drone-like sound is recognized, the system outputs direction information and links a PTZ camera for visual confirmation.
Can it detect gunshots or explosions?
Yes. HZ-SN-16 can be configured for sudden abnormal sound events such as gunshot-like sounds, explosions, impacts or other high-risk acoustic events. The system can locate the sound direction and trigger camera linkage for quick response.
How does the PTZ camera linkage work?
When an abnormal sound is detected, HZ-SN-16 outputs the sound source direction and controls a compatible network Speed Dome Camera through the ONVIF protocol. The PTZ camera then turns toward the sound source for visual verification.
Does HZ-SN-16 support 360-degree monitoring?
Yes. HZ-SN-16 supports 0°–360° omnidirectional acoustic detection, helping reduce blind spots in traditional video surveillance where the monitoring direction may be unclear.
How fast is the response time?
The system response time is less than 50 ms, allowing fast abnormal sound localization and rapid PTZ camera direction adjustment.
Does sound recognition require training?
Yes. Recognition of specific sounds, such as drone acoustic signatures or other customized target sounds, requires prior sampling and training. The recognition function is implemented through backend services.
What cameras can it work with?
HZ-SN-16 controls network Speed Dome Cameras through ONVIF. It is designed to be compatible with most ONVIF-supported PTZ cameras on the market, but final compatibility should be verified according to the camera model and control protocol.
Can it store evidence after an alarm?
Yes. The system can support audio and video retention before and after alarm events, helping operators quickly review relevant evidence without searching through long periods of video footage.
Where should HZ-SN-16 be installed?
HZ-SN-16 is suitable for locations where abnormal sound direction is important for security response, such as:
  • Low-altitude drone monitoring points
  • Public safety and emergency response areas
  • Industrial parks and campuses
  • Perimeter security posts
  • Critical infrastructure and restricted facilities
  • Existing video surveillance systems requiring audio-triggered upgrade
