Actually the Prosilica areaDetector driver cannot currently do this. The reason is that the camera is found by its Unique ID rather than its  IP address. This is convenient because cameras can use DHCP and do not need a fixed IP address.  But it won't work across subnets because it requires a broadcast to find the cameras by Unique ID. We could modify the driver to add logic to allow IP address or IP name in place of Unique ID.

Subject: Re: AreaDetector: Prosilica camera on different subnet?

If the both the IOC and camera allow a default gateway to be configured,
you can keep them on separate subnets and simply use a router.  The
router can be either a server or a multi-layer switch with an interface
on each of the subnets.  The router interface addresses will be the
gateway addresses configured on the IOC and camera.  From there one
could create policies to allow only traffic from the (2) devices to span
subnets if there are security concerns.
