Actually I said DVR, VCR is DEAD.
Now that I have a regular keyboard (I replied from my tablet earlier), go to Sam's club, get either thier 4 or 8 camera kit (kit meaning everything you need is in the box, except if you get the 8 camera kit you may need to buy the other 4 cameras). They are precut wires with connectors already built in, run all your wires to a central location, mount all the cameras plug all the cables into the dvr (very important) BEFORE you plug the dvr into the wall. Run a network cable to your network, program the system (some even allow for email or texts with the picture). Leave your computer monitor on the cameras, that way if they break in and want to steal the evidence then you have given them a decoy to steal, and your dvr is still safe and sound.
Heck, I even have a DVR lock box (about a 250.00 box) I'd sell you cheap. Mount it, lock it and it will slow them down even more.
