I am new to this and tried researching and quickly found out i have no idea what most of the specs mean on these cameras and dvr cards. I just opened up a shipping store a few months ago business is doing good, so good now i am starting to worry about the money we have on hand at anyone time and sometimes packages spend a few days in the store over the weekend with no body there. We do more then shipping we also do bill pay so we can have a couple hundred in the drawer one minute and tens of thousands the next. We do have a safe bolted to the ground but u can never know what could happen in the time your handed the money and when it goes into the safe and sometimes employees are to lazy to put it away. So i was thinking about setting something up with 3 cameras 2 upfront and 1 in the back with all the packages. Thing is i don't know who is reliable and what cameras are anygood. I just need something so that i can identify someone if anything happens, and to keep an eye on employees we have about 5 computers in here so was just thinking about hooking up the system to one of them. I am very good with computers i put together the ones in the store so if i am pointed in the right direction i can put it together myself.
