Unfortunately I have no schematic, one was never issued and i wouldn't fancy my chances at trying to draw one up.
The main problem is when a GPRS connection is the only active connection available it refuses to work, the software cannot connect the mobile phone to CCTV servers.
On the phone if WiFi is active there is no problem, if the WiFi connection is turned off, EagleEyes just gives "Login Failed", EagleEyes in Jbed "Sys.Login.." and it hangs, Supervisor asks if it can open a GPRS connection but then fails to login.
