A free program for Android, by Swann Communications.

SwannView is a video-viewing app for your Android phone that allows you to watch live streams and recorded videos from your Swann CCTV directly on your device. It is compatible with all major Android devices, including tablets and mobile phones.

The app allows you to watch up to 4 channels at once and enables you to record video on your phone and watch it later. You can capture images from your camera, and save them to the gallery so you can view them later.

You can also drag the camera around to change the viewing arrangement. The app allows you to control the PTZ (pan, tilt, zoom) of the cameras remotely.
