So i am new to this site, looking at getting a camera system installed and hooked into my tv in my master bedroom. Looking at prob 4 cams at first maybe more later on all outside at first. In searching for 3 hours tnight it looks like these HDW5231R-Z cams are good? Any pointers what else would i need if i buy 4 of these also where should i buy them ? I also see hikvisions cams are good but the ones on amazon are grey area? So i dont know where to buy if i go with that company? Any help would be much appreciated!
