OKIOCAM T has a zoom button on top of its camera (the white circular button). You can press the zoom button to cycle through 4 zoom levels.
OKIOCAM S does not have a physical zoom button. However, you can use our free app, OKIOCAM Snapshot and Recorder, to gain zoom functionality. Once installed, you can use the app to zoom in and out, rotate the camera’s image, and automatically adjust focus, exposure, and white balance.
