Power Specs on Spotlight Camera (wired) for long run installs

I'm looking for the power specs on the spotlight camera (wired) aside from 'AC adapter'.My plan is to replace POE cameras installed outside and utilise the Cat5 cable as power into a CCTV power supply box (as I have 4 cameras ran to a single location, 4 outets + transformer boxes is too much). Most CCTV is 12v but as the spotlight cam has additional lighting I'm thinking maybe I should opt for an 18v power supply box?Has anyone done this or know the EXACT power requirements for spotlight cam?[https://www.amazon.ca/Channel-Distributed-Security-Cameras-Supply/dp/B07DL43LTJ/ref=sr\_1\_1\_sspa?dchild=1&keywords=power+supply+box&qid=1603402465&s=electronics&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExVEowQUc4MzdXNEtKJmVuY3J5cHRlZElkPUEwNTU0OTY2MjRESVBJSVU1UEM1WSZlbmNyeXB0ZWRBZElkPUEwMTYxNzkyM0JZTkdIRjNRNjBMTiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=](https://www.amazon.ca/Channel-Distributed-Security-Cameras-Supply/dp/B07DL43LTJ/ref=sr_1_1_sspa?dchild=1&keywords=power+supply+box&qid=1603402465&s=electronics&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExVEowQUc4MzdXNEtKJmVuY3J5cHRlZElkPUEwNTU0OTY2MjRESVBJSVU1UEM1WSZlbmNyeXB0ZWRBZElkPUEwMTYxNzkyM0JZTkdIRjNRNjBMTiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=)
