9989 is not a port used in stable DAHUA firmware releases. You should review that, as it might expose a security flow in your camera.

I got that addy from a dahua tech in their forums

I don't have that port open, that's just to watch snapshot with smart TV from my local net. Who will want a snapshot from outside your local net while there are so many apps that will give you live feed?

path I found after updated firmware for snapshot is

http://ipnumber:9989/onvif/media_service/snapshot?channel=1&subtype=0

Hope this helps
