Depending on the purchase date of your panel, it will come with a 7-year licence which acts as a sum of credits (2555). This is because 7 years is equal to 2555 days. Therefore if you have an older V3 Classic panel or Windows/Mac/iOS and don't want to purchase a license for each device the credits on your account will be shared between the devices. For example, if you have 1 license but have 2 devices enrolled/registered to your account they will each have a 3.5-year license of CommBox Manage active until they will need to be renewed, this can support as many devices as you like.
