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!
