Homekit secure video

I have two Circle View Cameras which have stopped recording clips. There is alway a live view so the camera are connected and working. Stream and allow recording is set. If I set to any motion triggers the recording it works too well, many recording of light changes. If I select Specific Motion is Detected with all the options check, then nothing is recorded even when there are people in the view. The camera have worked for a number of year until now. What can I do to get them recording again?
