I've managed to check the operation of the cameras and DVR after, eventually, getting the App on both Android and IOS to connect to the DVR i.e. I can see video from each camera in the Apps. However, when I attempt to connect with the App on both Android and IOS using 'settings' so that I can check/alter the settings on the DVR the App crashes each and every time. In my view the app on both systems is flakiest at best and crap at worst.
Does anyone have any ideas I can try?
Thanks in advance, Cliff
