Motion Detection on Floodlight Cam

People only mode on my floodlight cam doesn't seem to be working properly, It notifies me for every motion it picks up. My other cameras tell me if a person has been detected in the notification, The floodlight cam does not, when it picks a person up the notification just says 'Motion Detected'. I understand that people only mode is not 100% accurate but my other cameras work a lot better than this. This is really annoying at 4am when my neighbours cat comes into my garden and the floodlight cam goes of but the spotlight cam doesn't. Does any body have any suggestions? MickD
