Network based IP cameras have become immensely popular because of their lowering cost, high resolution video capabilities, and integration of complex functions all over a single network connection. We recommend the use of our PoE IP cameras with network video recorder that we sell because our NVRs offer easy configuration of our cameras. When installing a IP camera system, the first challenge is networking, i.e. knowing how to assign different ip addresses to each camera and NVR that abides by the IP address scheme or subnet of your network. After you get that done, you have to worry about setting the resolution and frame rate for recording that you would like. With 3rd party NVRs or ip cameras software this can be a daunting task.
