Config help - Juniper switches, Pelco VxPro system

Hi /r/networking

I need some help. For reference, here is topology: https://i.imgur.com/TFlWRPr.jpg

I have 3 EX3400's, passing vlan 604 via xe-0/2/2 on all back to a QFX5100 VCP, all ex3400's connect to re0. These xe interfaces are dedicated, no other vlans sharing the port, so they have 10GB carved out. Bandwidth seems to be about 250Mbps, so not much.

Connected to EX3400-1, there is a Pelco (Pelco logo on Dell) server connected to ge-0/0/21, camera in ge-0/0/33 (sorry for wrong port # in that drawing). Both ports are in vlan 604. No special config. It is the Pelco VxPro system.

Connected to EX3400-2 and EX3400-3 are also cameras, same vlan, vlan trunked along as you'd expect. Pelco server sees all cameras. Pelco server reporting significant packet loss albeit varying at times the amounts of it. It seems to be somewhat related to load but not a definite correlation. According to the Pelco client machine, it defines the packet loss as lost RTSP packets... sequence numbers missing.

I did see the Pelco guide (https://support.pelco.com/s/article/How-to-determine-UDP-packet-loss-of-IP-cameras-connected-to-Digital-Sentry-systems-1538586677120) to debug it further. I'll go do more of this when I am at the site next and have access to the test env.

The loss is present on EX3400-1 with camera, workstation, and server all in same subnet/vlan/switch. So obviously the fiber links are not the issue. I also verified on the ports on ex3400-1 to see:

Are there any config things I should know about IP cameras on Juniper? I'm semi green and I have no experience with IP cameras and networks to back them up.
