I'll respond in English, if you don't mind.
The terms “active” and “passive” refer, as we understand it at this point in time, to the GPS type of systems. Active refers to the notion that the system is essentially in continuous contact with the monitoring centre. How often it actually interacts with the monitoring centre is, again, one of these operational specifications: does it need to be every five minutes, every 10 seconds? But the system is basically using cellphone technology to be in contact with the monitoring station on an ongoing basis, so in theory you could track someone's ongoing path. A passive system, as I understand it at this point in time, is one where the path of the individual during the day is logged on the device itself and there's no communication with the monitoring centre until at some point in the day, when the device is connected up to a transmitting unit, if you will, that downloads the information to the monitoring station and you can then see where the person was during the day, but of course it's hours later.
So depending upon the requirement you have, you can use either an active or a passive system, but it's all dependent upon how much oversight you need to have of the individual.
