NoCodeStream

There is no code stream when I log in and the network program restarts constantly after upgrade.

1. Check if there is IP conflict or network disconnection.
2. Check if the device is under normal power supply. 
3. Check if each connection line is loose inside the device after disassembling the camera. 
4. Check if the application program of IPC is corresponding to the model, and check if N/P format program is correct. 
5. Check if the control and WEB are correct, there is control running permission under WIN7, you can delete the control under C:\Program Files\webrec and eliminate IE buffer memory to reload control and WEB. Please run IE as administrator for WIN 7, you need to install QuickTime plug-in if it is non-IE browser.
