ip surveillance multicast network config with DAHUA NVR

[ConceptsL5]

In our network we have a 3750X  switch operating as our core switch. We also have four 2960S switches. Three of the 2960S switches are plugged directly into the core. The fourth is plugged into another of the 2960's. One of the 2960 switches is our "camera" switch. We have 1 Dahua hikvision NVR and 18 cameras plugged into the camera switch. We have VLAN45 configured to be our camera VLAN. All switchports which have a camera or NVR connected are configured with "switchport access Vlan45." In the NVR configuration we can configure it to send a video stream to any multicast IP in the multicast address range and a port # in the range 1025-65000.

How would we configure our switches/network environment  to enable a multicast video stream. What configurations would we need on the switches ?

Thanks

Thank you for your assistance. From what I can tell this would be a wireless solution. Would there be a way to restrict it to LAN?
