What's new in 4.0.1 PTZ cameras • New on-screen arrow keys around the picture replace the joystick: press and hold to move, let go to stop. • Scroll to pick a preset number, then Go, Set or Delete. • Presets on Magic recorders now go to the number you choose. • Zoom, focus, iris and preset controls work again in portrait. Viewing • Lock the controls on screen in landscape so they don't hide after every tap, or hide them with one tap. • Record button added for Prism recorders, to save a clip of the selected camera to the gallery. • Prism: sound now follows the camera you select, switches faster and no longer mixes audio from other cameras. • Prism: sound keeps playing when a camera switches to its higher-quality stream. Fixes • Fixed a crash when changing months in the playback calendar. • The playback calendar now reliably marks the days that have recordings. • Picture-in-picture from a multi-camera view is more stable when the app is in the background. • The launch screen now shows the full Prism logo.
