Sooo as way of hopefully summarising what I need to buy.... now that is has got totally out of hand! (You guys must have shared in Dahua or something!).
In my basket I have:
1 x IPC-Color4k-T - Rear Garden Door
1 x IPC-Color4k-T180 - Front drive overview
2 x IPC-T54IR-ZE-S3 - Front door and rear side passage
3 x
IPC-Color4k-X - 2 x Front Drive (still torn between these and the T but not a big fan of the dome wall mount) and 1 x for rear garden
1 x NVR16CH-AI (upped from the original 8ch for only $20 seemed worth it for the future)
2 x PFA152-E Pole mounts (presumably the 4k-X mounts direct to this and doesnt need a junction box?)
5 x PFA130-E Junction box
I would likely mount the T180 on the soffet as its up high for overview, saves a bit on buying the pole mount and the wall mount (every little helps)
I am happy to install the HDD in to the NVR myself and source separately (something I am good at - IT / Networking).
Need to source a suitable PoE switch, will likely get a ubiquiti one as I have a lot of their kit already.
Does the above list sound right? If so I might fire off a DM to Andy and see what he comes back with.
