wifi vs PoE CCTV camera setup

vikrantl

I am deciding on the CCTV system for my apartment.

The real purpose is not active monitoring, but to monitor after an event.

I have four options in my mind.

1) Have 8 WIFI cameras with built-in storage, connect laptop or smartphone on demand to view saved and live video
2) Have 8 WIFI cameras with a WIFI-NVR
3) 8 PoE cameras with a NVR device and a PoE power device
4) 8 PoE cameras with a combo unit with NVR and POE built in

Any detailed information would be helpful for me and also for prospective new installations

thanks all
