# Make sure local dns lookups are enabled on your router.

# 'Wan: Use local caching DNS server as system resolver'

# Requires enabling motioneyeos web control port:
# On the motioneyeos device set webcontrol_localhost to off in /data/etc/motion.conf then reboot the camera.
# You should now be able to access web controll via port 7999. Test with a browser.
