If you want your Nest Cam to store video recordings in the cloud so that you can retrieve them later on, you have to sign up for the company’s Nest Aware subscription service. Nest Aware is Nest’s subscription service for Nest Cam users that allows you to store video recordings in the cloud for up to 30 days, among other features.
An example of a CAM that is charged to only a subset of tenants might be the charges for cleaning the food court area, where all of the vendors in the court collectively cover the higher cost of cleaning the tables on a frequent schedule.
Landlord and Tenant negotiate CAM charges before signing the lease, so the charges vary from lease to lease, and operating costs that can be billed as CAM charges by the landlord vary from tenant to tenant.
Generally, landlords want CAM charges defined so broadly that they can pass through a majority of their operating expenses to tenants.
So it is also important that your lease differential between "variable" and "fixed" CAM fees and include some sort of cap, or, maximum your CAM fees can be increased each year.
This rate of increase should be a separate consideration from how much you basic rent increases each year.
