WAlert- The 3D Spatial Security Device for Home

A single WAlert can detect intrusion into a house without the installation of wired/wireless sensors


We at WataSensor are fundamentally changing the home security market by delivering a simple, low cost, true Do-It-Yourself (DYI)  security home device based on patented revolutionary subsonic frequency sensing technology.  The patented subsonic frequency sensing technology can detect subsonic sound below the human hearing (sub 20 Hz). This band of frequencies is normally used in seismographs to monitor earthquake. The unique aspect of subsonic frequency is its capability to travel  long distances and get around obstacles with little dissipation.

The WAlert™ is the world first 3D spatial home security device that is just plugged into any power outlet, easy to set up using Smartphone, and simple to use. It requires no installation, no monthly service, and no contract. The WAlert is based on a unique patented intrusion sensing technology that can detect intrusion into a house with a floor space up to 2000 SQ, without the installation of any wired or wireless door/window contacts or glass break sensors. Upon detection of an intrusion, a siren is triggered to deter the intruder, and a notification is sent over the Internet to the owner’s smart phone via broadband network. It’s a compact and streamlined device, can be plugged into power outlet anywhere in your house. It provides you a peace of mind, and seamlessly interacts with your Smartphone’s, and tablets over Internet anytime and anywhere.
