Question about QoS (queues) further into the LAN

Hi guys

I’m scratching my head over something. In this diagram:

I want to prioritise CCTV traffic over the wireless link. Lets assume it is on a vlan away from the other devices. Will Queues on the CCR affect the incoming traffic shaping over the PTP link? Or would this need to be done via a switch on the far end?
