every day looses connection from internet!!
Do you really mean the internet, ie remote access from outside your LAN?
Or do you mean from web or app access locally on your LAN?
Suggestion :
Do some basic fault-finding to try to determine where the problem lies.
For example, assuming the camera is on the LAN as opposed to connected to an NVR or remotely accessed -
Does the Link Detect LED still show on the port the device is connected to?
Can you still ping the camera at it's IP address?
What does SADP show for the camera status and is it at the expected IP address?
Can you still see live video using VLC or ONVIF Device Manager?
Does the problem still occur when using a different (eg pre-made) ethernet cable?
If you terminated the ethernet cable, as opposed to using a pre-made cable, what wiring standard did you use?
What firmware version is the camera running?
How is the camera powered?
etc
