Fiber isn't really that expensive anymore. A prefab LC-LC patch can be pulled (very carefully) through 1" conduit.
The whole thing doesn't have to be fiber, either; a fiber link between the camera PoE switch and the "house net" (with DVR and PC) would keep a lightning strike from taking out the PC when it fries the cameras. This strategy could be repeated: with 2-3 camera switches, damage could be limited to "some" cameras.
Standalone fiber/copper mediaconverters exist. There's plenty of resellers with cheap enterprise gear. Just make sure to get the fiber that matches the transceiver (both connector and type), and note that SFP is a slot for a transceiver module (sometimes included, sometimes not). Best to standardize, here, so you don't need multiple flavors of fiber patch. You probably want SX transceivers (range = 550m) and multimode fiber with duplex LC connectors.
Netvanta 1531P (by Adtran) is a relatively cheap PoE switch with two SFP ports, I like them because there's no separate term-limited feature license keys as with modern Cisco ... and they're available from Amazon.
