I have dh-sd22204t-gn (its a ptz with no IR) installed outside. I have it setup to record on motion. I use the Normal profile. During the day everything works fine; it records on motion only. However, at night it records constantly so all I get is a black image. If I turn on an outside light, it works fine.
I can turn the lights on via motion if necessary, but the camera will still record the darkness between motions.
I've tried messing with the image settings, and sensitivity & threshold settings, but it hasn't helped.
I have several other dahua camera installed outside, and none of them exhibit this behavior of recording a black image.
Any suggestions
