Just setup a couple of 4550 systems and had installed Swann link 2.4 for Android (actually says 18.104.22.168 in the actual app btw). Initially connected fine to both boxes and was working for a couple of weeks. Last few days can't connect and says 'login failed'. Tried to see what options there are on the app and surprisingly few, so tried to see if there is a more recent version or some other Swann App and there are loads, many of which have reviews saying they don't work. One of the main purposes of getting these was to be able to remotely view - any offers which is the best App and version for Android or why it's suddenly stopped working and what the fix might be?
