## What is NOI?

Protect Against Invasion of Your Privacy!

Are you concerned that you are being watched? Are you staying in a hotel or Airbnb and worried about spy cameras? 

NOI helps you to detect hidden spy cameras using various different technics and methods. Find out if you are being watched using your iPhone without needing additional equipment!

Connect to WiFi network and start the Camera Wizard;
1- Scan WiFi network and discover connected devices to identify any suspicious device in the network.
2- Use magnetic field detection. Hidden cameras are usually planted in other objects such as a plant, alarm clock or a night lamp. Move your phone closer to the suspicious objects to find out if they are creating a magnetic field.
3- If none of the options satisfy you, look out for cameras manually. Our audio guides will help you to identify most common places hidden spy cameras are usually located.

NOI offers auto-renewable subscriptions. For more information about privacy policy and terms of use, please visit our website.
