Discover Device Potential deviceOwl is an AI point-and-shoot hardware device checker that helps you identify the make and model of devices, and reveal their privacy implications. Covert spy devices are cameras and microphones that are either miniaturized, or disguised as other trusted household objects. They have serious implications, because they can be well disguised, highly reliable, and are widely available for purchase. Household smart devices can enhance the convenience and peace of mind we have at home, but sometimes at a cost of privacy and security. With an eye towards privacy, deviceOwl helps you quickly identify these devices, providing both simple, and in-depth details about their capabilities. Simply point your smartphone at a device, and let deviceOwl intelligently check it, based on its knowledge of thousands of devices. If a device is recognized, deviceOwl provides details about the device's capabilities, helping you to make the right decisions about how to protect your privacy, and the privacy of the people you care about. Information includes make, model, privacy and safety considerations, sensors, network, storage, power, remote control, AI capabilities, and manufacturer information, including origin, parent companies, privacy policy, and the current government blacklist status of the manufacturer. FEATURES —————-- - Basic Edition helps identify popular consumer household smart devices. - Advanced Edition helps identify covert consumer spy devices, and provides in-depth device capabilities with a focus on privacy. - Regular device knowledge updates keep deviceOwl aware of new devices. - Heads up display and interactive guidance to make it easier to check devices. - Designed for traveling. Once installed and updated, check devices without a cloud or network connection. IMPORTANT NOTES & LIMITATIONS —————————————————---- - Checks visible devices that are roughly up to the size of a shoebox. - Please follow the guidance provided on safely and correctly checking devices. - Some devices may look similar to each other, especially under different lighting conditions, and from different angles. Please confirm all device detections using the reported make and model. - DeviceOwl is not a network device scanner, or camera lens reflection checker. Instead, it uses AI to visually recognize devices by their shape and form. - Does not identify individual components of dismantled devices, such as their circuit boards and other components. - Does not identify certain device types whose surface is dominated by an LCD screen, including TV's, tablets, and smartphones. Refer to the device type selection screen for the most current list of supported device types. - Due to the volume of sample submissions, Entropic Labs responses to device sample submissions may be limited.
