How to give priority to one port

Hi I have a problem, I need to prioritize one port 16000 over my wireless network, I want it to have priority over all other ports on the network , How can I do this? Its a DVR that I want all my clients to have access to. Thank you in advance for your help.

I am a small WISP , 30 clients with a mixture of routerbaord AP’s and some ubiquity Bulletts, Phasing out ubiquity as I become more familiar with Mikrotik.

It’s a lot to take in, but that’s QoS for you.
