Today our smartphones are practically extensions of ourselves. Technology continuously tracks us through our smart devices. The idea that they might be secretly listening to us, is unsettling and a threat to data security. But technology itself comes to our help to address that problem. The newly launched(in August 2025) privacy protection device Guardian Ultrasonic offers a solution. It can prevent covert eavesdropping by smartphones. Let’s learn more about Guardian Ultrasonic, its relevance, features and how it keeps your personal and professional conversations private.
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 UltrasonicKey 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.

Today everyone is busy, and group meetings for decision making is often a challenge. Video conferences offer a powerful communication solution here. Its technology existed since the 1980s, but adoption came in the 2000s. However, it really shot into global fame during covid pandemic, when we avoided in-person meetings altogether. Soon after, video conferences became the new normal in our personal and professional lives.
Whether leading a multinational team, teaching a virtual class, or catching up with family away, video conferences bridge distances, making communication inclusive. Let’s learn about its benefits, features, best practices, and different room setups for doing video conferences.
What are Video Conferences?
Video conferences involve real-time, electronic face-to-face meetups where people from anywhere in the world can join in virtually, via computer or mobile phone. Technically, it involves 2 components:
Audio/Video hardware like microphone, camera, digital display screens.
Video conferencing software platform. Examples: Zoom, Microsoft Teams, Google Meet, Cisco Webex.
The hardware connects to the internet through the software, and transmits audio-video signals among meeting participants. Compared to simple phone calls, video conferences use collaborative tools, visuals and screen sharing to make conversations richer.
Benefits of Video Conferences
There are many benefits of using video conferencing to communicate and connect. Here are some:
Cost savings: Video conferencing reduces costs of travel, lodging and meetup events.
Time efficiency: You can schedule and conduct meetings instantly via video conferencing.
Flexibility: Supports hybrid work systems, and on-the-go access to meetings.
Collaborations: Enables collaborative tools like screen sharing, real-time file editing and exchange among participants.
Global reach: Connects people across teams and clients worldwide.
Productivity improvement: Speeds up brainstorming, problem-solving, approvals and decision making in work environments.
Eco-friendly impact: Reduces carbon footprint by reducing the number of business trips.
Features of Video Conferencing
HD video & audio: Video conferences enable clear communication without breaks or lags. That means continuous idea sharing and teamwork.
Screen sharing: People can present and share documents, do live demos during video conferencing. E.g. You can highlight your key points, and share your screen with others.
Virtual background: During video conferences, you can keep your company’s logo, or other related information in background.
Recording facility: You can record and archive virtual meetings, which are like minutes of meeting, for future reference. You can replay specific parts, or full recording later for actionable insights.
Breakout rooms: These are small virtual meeting rooms within a large virtual meeting room during video conferencing. Breakout rooms enable more focused subgroup discussions or activities. They are common in training workshops and classrooms
Video Conference Best Practices
Test your tech: Before joining a video meeting, check your camera, mic and internet connection. Even if all set up, a quick heads up can prevent last minute hiccups.
Use professional background: It keeps your background clean and private, adds a professional look, and maintains brand consistency. Use a static physical or virtual backdrop. Also, ensure meeting attendees focus on you, not the background.
Mute when you are not speaking: It avoids background noise distractions. So that other people in the discussion can hear clearly.
Engage visually: While speaking, look at the camera, not the screen. That simulates eye contact with people you are talking to.
Have a clear meeting agenda: A pre-set agenda keeps your video meetings focused and time-bound. Thus people don’t drift from attention and engagement.
Implement security & privacy policies: Follow data loss prevention (DLP) protocols like single sign on (SSO), multifactor authentication (MFA). That helps avoid leakage of your sensitive data.
Before Setting up your Video Conference Room..
When planning to set up a new conference room, or redesign an existing one, remember these:
A well-designed room can make your video conferences more effective. It enables smooth communication and collaborations, leading to better work productivity.
