Hello everyone. I came across this site after endless hours of stumbling through the sea of security systems, and hope that the knowledge gained here might help. My present situation is i need a security system of course, but im trying to stay under 1200. the best one Ive found for the money is this one. http://www.ebay.com/itm/NEW-Swann-8-Channel-HD-NVR-Security-System-2TB-HDD-4-x-1080p-3MP-IP-Cameras-/121243204311?pt=US_Security_Cameras&hash=item1c3aa87ad7. This only comes with four cameras which im ok with as i can get more later my shop is not that big. 50 x 100 steel buildingw/ enough parking for about 15 cars. i would rather have good quality at this point and add on as i can afford. love to be able to see whats going on using my phone. I would like to cover a few places, but am new to this and dont want to make the mistake of buying twice. Any input or suggestion would be grateful.
