WiFi connectivity to my iPhone was easy to do, when utilizing the EZ iCam app. I love how I am able to use my phone as a viewer/controller while I have the camera adapted to my bicycle helmet. And when it comes to the video, clarity is key. Great variety of mounting options are a plus as well. You can do a lot with this amazing 4K camera such as a body camera, dash cam, adventure cam which are some of my immediate uses. Great camera at a great price. Two thumbs up.
