What is Guardian Ultrasonic?
Guardian Ultrasonic is a privacy protection device that can disable a smartphone’s ability to record ambient sound (background sounds). Its ultrasonic emitters jam the phone’s mic, making it temporarily deaf to its surroundings. No hacking, or software involved here. You just need to place your phone on top of Guardian Ultrasonic. Now you can talk freely without worrying that smartphones might be listening silently.
Why it Matters
Consequences of leaked conversations, especially critical and sensitive ones, can be catastrophic- reputational damage, competitive sabotage, legal exposure and even more. Whether you’re in a high-stake business meeting, or just need privacy during personal conversations, Guardian Ultrasonic ensures your smartphones are not spying to steal data and information.
Who is it for?
Guardian Ultrasonic serves all who want privacy in conversations, whether personal or professional. This is especially important for entrepreneurs, business executives who are prone to unintentional data leaks during meetings. Similarly for professionals like journalists to keep confidentiality when working in high-risk environments.
Guardian Ultrasonic Key Features
- Microphone disabling:
If you keep your smartphone kept on top of the device, it prevents the phone from picking up any sound from the surroundings. - Compact design:
This is a discreet, easily portable device. Roughly the size of a tablet, and weighs only 500g. - Battery powered:
4000 mAh rechargeable battery powers Guardian Ultrasonic. That offers 8+ hours of active use, and over a week of standby. - Wireless charging(upcoming feature):
This feature would enable users to charge their phone while protecting privacy.
How Guardian Ultrasonic Protects Privacy
Guardian Ultrasonic protects users’ privacy during conversations. It can prevent hidden phone trackers recording audio from their surroundings. Thus it can prevent potential data loss from our personal and professional lives.
In order to secure conversations, Guardian Ultrasonic produces inaudible ultrasonic sound waves, with frequency between 23kHz–26kHz (we humans cannot hear sound above 20kHz). These inaudible waves block or scramble hidden tracking systems that usually rely on microphones, or audio-based signals. As a result, you can talk freely without worrying about covert privacy invasion.
Final Thoughts
Today, technology tracking us through our smart devices is becoming the new normal. But you can choose to prevent any intrusive tracking, and protect your personal and professional data. Guardian Ultrasonic devices help safeguard your conversations and privacy proactively.
