There are so many different kinds of surveillance cameras that it can be hard to choose the best one. I need al little help figuring out which cameras will work best with a networkable 4 channel dvr. I’ve looked at surveillance systems at several websites online and the choices can be pretty daunting. There are IP cameras, IR cameras, covert cameras, turret cams, and about a dozen other different types of surveillance cameras even though I’m pretty good at wiring CCTV systems, I need help choosing the cameras that are right for my application. I want to get the job done right, but I don’t want to spend more than I really need to.
