Precaution
If multiple objects move over a period of time (remember, we usually talk about parking lots or similar open spaces, which may be frequented by hundreds of people and / or vehicles), the auto tracking camera will try to lock the fastest or largest moving object. What if a car is passed by and a person is trying to break into a parked vehicle or pass through a hook? The malicious activities of the driving vehicle are completely irrelevant. The camera's sensitivity setting determines how much motion is needed to trigger tracking. Unfortunately, it's just a setting between 1 and 10. It is not set to "person" or "vehicle", so it needs to be tested after installation to ensure sensitivity and accurate operation.
