I have ports of "IP Cam Viewer" for Android to other platforms. More features will be added over time.
iOS:
Look for "IP Cam Viewer Lite" and "IP Cam Viewer Pro" in the Apple iTunes app store.
Blackberry QNX OS:
Look for "IP Cam Viewer" in the Blackberry World app store. Note: native code is not allowed for blackberry so some drivers (i.e. h.264 dvrs) will not be available for now.
Windows Phone 7/8:
Under development. Target end of the year completion. Update: aborted because MS decided phone8 will not be backward compatible. Will restart on phone8 when it's get more popular.
Table/Desktop ports:
I don't have a desktop Mac/PC version yet. For now, you can use BlueStacks to run Android apps on both Mac and PC. After installing BlueStacks, download and install IP Cam Viewer Lite.
