High Power Indoor Wall-mounted Acoustic Repellent Device

EVL1.jpg

High power Acoustic Repellent Device can generate high pressure level sound wave to produce auditory stimulation on human body, and cause shock, discomfort, anxiety,uneasiness and other unhappy reactions to force the intruder to flee away immediately.

The acousticrepellent device is world-leading security equipment which can effectively interfere with criminal behaviors and actively drive criminals away, and saveproperty and life to the greatest extent. In addition, the device can beintegrated with common security systems to provide intelligent active defensesolutions.

The high poweracoustic repellent device is composed of piezoelectric buzzers, controlcircuits and built-in lithium battery.

It can work alone or in a network, also canbe integrated with various sensors (such as infrared, microwave, vibrationetc.) to form a powerful active driving system.

The acoustic repellentsystem is applicable for family and businesses, as well as public securitydepartments, financial and other key security units.


Work Theory

After the soundunit detects the switch signal (trigger signal), CPU of patent algorithmgenerates 2-4khz audio signals randomly changing with time, and emit a high frequency sound

of 128dB@1m through the power amplifier to achieve effectiveactive dispersion.



Features

Patent algorithmand control, can generate 2-4khz random high frequency square wave signals, notolerance to human body

High power sound of125 ± 3dB@1m causes strong physiological and psychological shocks, no permanentdamage to people

Robust and durablewith aluminum alloy and stainless steel mesh

With built-inlithium battery, not affected by external power supply

Simple andreliable, can work indoor and outdoor

Seamlessintegration with various security systems
