Right, actually you may configure up to 3 different filters working simultaneously on each camera. Each filter has to be configured in detail to avoid false alarms or false response.
Also you can do it on the software, not only on the camera. So if something fail on the field without the software, you can set it thru web browser, with the right access obviously.
It is nice, actually ONSSI works fine with Sony too, it accepts DEPA. If you don't like RSM, it is another option.
