Every new camera license comes with a one-year software subscription agreement (SSA). Because all licensed cameras must have the same subscription end date, a portion of that one-year subscription is used to match the end date of the existing cameras. Any remaining portion of that one-year SSA is then divided equally among all licensed cameras.

For example, suppose you have two IP cameras with six months remaining on their SSA, and then you add a new IP camera with a one-year SSA. Six months of the new camera’s SSA is applied to match the remaining portion of the existing cameras’ SSA. The remaining six months of the new camera’s SSA is then divided among all three cameras. Thus, each camera’s SSA is extended by two months (six months divided by three cameras equals two months). All three cameras now have an SSA that expires in eight months.

NOTE: IP cameras receive twice as much weight in these calculations as analog cameras. However, all licensed cameras have the same subscription end date regardless of whether they are analog or IP.
