I get this with Meshare on my Nexus5 phone.
I have one SmartLink 720p wireless camera, it randomly keeps saying the device is offline from within the App.
The wireless signal is fine (it is quite close to the router - and no I do not want to use a cable), the IP address of the camera and my phone remain the same, my external IP hasn't changed either (but the Zmodo system should handle this)
Did anyone get to the bottom of why it randomly reports it is offline (I can still ping it when it says offline).
I assume this is an issue with the Zmodo backend servers?
