We typically work on a lease model, so we lease the units to the agency on a dollar per unit, per day basis. The agency only pays for units that are what we call “on leg”. They only pay for units that are being used, which allows the agency to very accurately budget what their utilization is going to be, what their costs are going to be.
The typical cost for the system, which includes the hardware, and all the services, and all the training, is $5 to $10 a day to the agency, and then on top of that, it's whatever agency costs there might be in terms of personnel.
The agency infrastructure is minimal. It's communication lines and computers. We set it up so that there are no additional costs.
