Cameras are always working well and fine with the help of the commander software on my computer system and I have never faced any kind of issue while watch the recorded footage or images. To be precise my computer have never showed me any kind of error or problem which having access to the Logitech Alert system using the commander software. But on the other hand my portable devices like mobile phones always had some of the other kind of issue with it. Applications like Mobile viewer and iPhone applications have consistently ended up giving some error message. They actually use to work very well for one week but the next week I use to receive a 503 error then again next week they use to work fine and so on. Currently the status is that I get a error message stating “No cameras or sites have been defined. Please install your cameras using Logitech Alert Commander on your computer." From the time I started receiving this written error message, I have noticed that it never went off. The error message stayed the same for next one month without fail and without changing. I am really frustrated and tired of this issue. Please help me out, if anyone aware of this problem and error. I think I did a mistake switching to this system, earlier I was with older wilife system which was very much stable and proper.
