Buying new system. Which one?

[NorthShoreWhaler 0]

I am looking to buy/install a system at my company. Can't figure out what to buy.

 

What I want:

Management/recording via Packaged NVR or I will install software on my own to a server

 

Outdoor HD IP Cameras Start with about 10 cameras may go up to 30 later

 

I would prefer a package I can buy with everything but not required. Any recommendations? There are just too many brands out there.

 

Thank You!
