Upgrading to OS4 on my iPhone killed APlayer, but thankfully ASee steps in to replace it. Works fine with my Q-See 8-camera setup. Wish it saved your camera preferences from launch to launch -- or maybe it does; theres no help of any kind with the app, so who knows what half the buttons do. The support site is in Chinese only, unfortunately. Other than that, you cant beat it, or the price.
