Private network vs office network
You can install the NVR and cameras on your existing network, which saves your efforts and costs. You can also install the system on a dedicated private network only reachable by the NVR. Although this involves installing a new network and thus increasing the costs, there are some advantages of using a private network:
the video streams are protected.
the cameras are protected because they cannot be reached from outside the network.
easier to determine bandwidth requirements.
better quality of service since bandwidth is known.
