Thanks for your response. I got that. The reason for having this idea is because my front door camera is facing the street. The street has traffics all day long but just few persons may came into my camera. So the camera will detect traffic motions(setting for motion detection is on ) and record thousands of it and useless but no person in it. That is not what I want. I don’t concern the traffic. I only concern if there are persons approaching to my front door. Additionally because the traffic motion is more often to trigger event recording, so when the camera has been triggered for event and recording(the completed event may be last 5 minutes long), if a person approach the door from the 2nd second to 4th second, this event record will not label for person detection. So I can’t filter it out and I don’t know there is a person approached my door unless playback the entire event video. Go back from beginning, because hundreds of traffic motions event records a day, I can’t recognize when and which one has person have approached my door. For what I was thinking, it has the feature for person detection already, why it can’t just record person detection. It could make your camera smarter. I hope you could understand what I said.
But anyway, if it doesn’t have this feature I want is fine. This is just my suggestion your company may could consider in the future. Thanks.
