Hello from Sheffield, UK. 
I have just purchased an Avtech AVI321 IP dome camera and wondered if anyone can solve a problem. I have a wireless router and the camera comes to this. The software recognises the camera's IP address but will not connect to it. Initially I had no problem but once I set it scanning to 4 presets I've never been able to connect back up to it. Even when I power the camera down and restart it goes back to scanning the 4 presets. It is like it is in auto pilot and never to come out of it. 
  
Any help would be appreciated. 
  
Regards 
  
Nigel
