Change the factory default credentials immediately upon setting up the device. Use a unique, complex password combining uppercase letters, lowercase letters, numbers, and special characters. If the device supports Two-Factor Authentication (2FA), enable it. Disable UPnP and Restrict Port Forwarding

Accessing a private camera without permission—even if it isn't password protected—is often considered a crime under "Unauthorized Access" laws (such as the CFAA in the US).
Never use viewerframe or default paths. Most modern cameras (Amcrest, Reolink, Hikvision) allow you to change the HTTP root directory. Rename viewerframe.html to something random (e.g., a8d3k9f.html ). Disable UPnP and Restrict Port Forwarding Google returns
If you do not need to view the camera from outside your local network, disable remote cloud viewing entirely.
Manufacturers regularly release software updates to patch security vulnerabilities. Enable automatic updates if the device supports it. Never use viewerframe or default paths
Many of these cameras may appear to have a login screen. However, attackers often bypass authentication entirely by directly requesting a specific internal URL. For example, researchers have found that simply requesting a URI like /out.jpg or /live.sdp can return a real-time screenshot from the camera, even if a password prompt is shown on the main page.
