When setting the camera motion detection there are 2 settings (Sensitivity) and (Threshold).The manual does not reference Threshold. When the camera is set Once it begins triggering recording the red and green indicator comes on the screen, then the red goes off and green continues for a few seconds and goes off, then the red and green reappear immediately and sequence happens again. There is no movement in the picture that is discernible. I have tried settings from 1 to 100 and once the motion triggers the sequence continues. These are 1080P motorized zoom cameras. They are not being zoomed when this happens.

Thanks for the info. The problem turned out to be a setting change for the encode on these 2 cameras. I had set them @ 720p instead of 1080p so I could capture @ 30fps, what I didn’t realize was that they were recording @ 1080p and that we are unable to change that. So as soon as they detected motion they would switch to 1080 and when the recording stopped they switched back to 720 and this looked like motion so they would start recording again and this loop would continue until record was deselected. Maybe a firmware update could correct this and allow changing the recording resolution to match the encode selected on the main stream page on the DVR. The settings are allowed on the web page setup.
This is not an actually problem. Our DVRs, NVRs and IPCs can record at a different FPS and some at a different resolutions based on the Encode Type and Schedule recording. If The recorder is schedule to record motion then under encode type click on the scroll down and choose MD and change the Resolution and FPS under there. Now if you are recording both (regular and MD) then you will need to change those options in Encode.
