Even if you choose the wireless option you are still going to have to get power to the cameras, which looks like it will be POE. Surely if you are going to have to run Cat 5e (dont use Cat 6 its not as flexible) to the cameras for power you can get the cables all the way back to the NVR or a POE switch?
Cheers both, yeah you are right the wireless ones aren't particularly more flexible.Don’t bother with Hilook. Just stick to Hikvision it’s daddy company.
How does Reolink stand in the market, this looks a great deal https://reolink.com/product/rlk8-410b4/ and the cameras are well reviewed quite well on Amazon etc. £250 for 2tb NVR and 4 POE cameras looks solid deal.
