I tried the trial version and it works great (far fewer false positives than the camera systems built in DVR/ motion detection software which gets fooled by the image noise from high ISO at night where as vitamin d video only really gets false positives from things like car headlights and shadows of branches if it is windy and the sun is in the right angle.
I would like to buy the full version one day but currently have 4 cameras and cant really see my self needing more than that but the purchase options seem to only be 2 cameras or unlimited for significantly more.
