FAQ
Can I still receive calls and messages? + −
Yes. Guardian does not block your mobile signal, Wi-Fi or Bluetooth. Your phone remains fully connected. Lift it off Guardian when you want to use its microphone for a call or recording.
Is Guardian Ultrasonic a jammer? + −
No, not in the traditional sense. It doesn't block radio signals like mobile data, Wi-Fi, or Bluetooth. Guardian Ultrasonic uses ultrasonic acoustic waves (high-frequency sound) to physically interfere with microphones.
Does it block all microphones in the room? + −
Guardian Ultrasonic is designed to protect you from your devices recording your private conversations. It does not cover the whole room. (Be careful with products claiming to do so β they are usually misleading.)
Does it work with phone cases? + −
Yes, it works with most phone cases. Certain phone cases with a subpar build quality can sometimes block the microphone slightly. In those situations simply place the phone on the device without a case.
Does it require an app or setup process? + −
No, Guardian does not require any apps or setup ceremony. In fact, it has no internet access and requires no software updates. It just works.
