Home security set-up advice

Looking for advice regarding a potential multiple camera set-up.

Now that we have FTTP and upload is faster than dial-up, a home security system with ability to access video externally is realistic.

I have 3 NAS already but for sake of security would probably purchase a stand alone NAS for storage and review of video from security cameras.

I'd be looking for a minimum of 1080p with night vision (if only to see local wildlife) that would be hard-wired to the home network and hopefully PoE.

App or remote access a necessity. "Intelligent" features like facial recognition and being able to pan around to follow movement also preferable.

Probably looking at 3 or 4 cameras, each to cover one corner of the house and land.

Thanks in advance.

Have a look at http://www.broadbandbuyer.com/ they are also supposed to be very helpful on the phone as well

Thanks
