In some cases, it might make sense to implement a new, dedicated IP-Surveillance network in conjunction with a general purpose network.

In this example, a dedicated IP-Surveillance network may be needed at the head office for reasons of bandwidth and security. In this case, all video from the four cameras are recorded locally and video traffic is isolated to that particular network, except when a viewer on the general purpose network wants access to video from the cameras or when an event is triggered to send video over to a user on the general purpose network. Since access to video using the general purpose network (and the extra load it causes) is temporary, it makes sense to have the two networks work in combination.

When building a new network or adding capacity to an existing network, calculate 30% to 40% more capacity or Mbps. It's better to have extra capacity, which gives you the flexibility to increase usage in the future.
