1. Try opening the avastUI, Real-Time Shields, Web Shield, Expert Settings, and check the 'Scan traffic from well-known browser processes only,' option. image1
Or
2. Open the avastUI, Settings, Troubleshooting, Redirect Settings, WEB, Ignored addresses: and enter the Ip address for your camera. image2
