Smart cameras and video doorbells are among the most privacy-sensitive IoT devices. Our 2026 security guide addresses their unique vulnerabilities. Buy cameras from reputable manufacturers like Ring, Arlo, Nest, or Eufy. Change the default administrator password immediately and use a strong unique password. Enable two-factor authentication on all camera accounts. Keep firmware updated. Disable UPnP on your router to prevent cameras from opening ports. Use a dedicated VLAN or guest network to isolate cameras from your main network. Cover or physically disable the camera when not in use. Review camera cloud storage settings. Regularly review access logs for unrecognized devices.
