Now you have both a camera offering full colour 24/7 and also being able to tell what caused the motion detection to be set off. Be it a human, car, pet or just the rustling of leaves; this camera will be able to tell you exactly that. And the NVR even sorts the alarms into categories of what caused the detection.
Varying lighting levels in the video shot will also be no hassle to deal with. The camera now has a stronger WDR. Going from 120dB to 130dB, even large variances in lighting will mean you will still get information from the whole shot.
