I've set up a Hikvision DS-7608NI-E2/8P/A NVR with four Hikvision
DS-2CD2042WD-I cameras plugged directly into and running on it. They're
all currently in the same room as I wanted to get them working before I
started running cable.

However, once they're installed outside, I will need to be able to plug
them into a TP-Link TL-SG1008P eight port PoE switch in the garage which
is connected to a router inside the house and next to where the NVR will
live. Problem is, as soon as I remove the cameras from the direct
connection into the NVR, plug them into the switch and then plug the
switch into the NVR, they can no longer be found by the NVR.

The house network has addresses in the range 192.168.178.***

The NVR is on the network at 192.168.178.50 but has an 'internal NIC
address' of 192.168.254.1 and has allocated the cameras with
192.168.254.22/26/28/11.

Is that where the problem is? If it is, what do I need to change?

Not quite accurate... when I run the cameras through the switch, camera
1 is detected and the image shown. The other three are not.

Are you saying that the DVR has its own DHCP server in addition to
your router?
