When having only the "person recording" enabled and "motion detection" disabled the camera only records about 15-20s seconds at a time. So if a person is detected it will come on and record the person moving around for 15-20 seconds and then stop recording and I can no longer see what the person is doing. Is this normal? As with "motion detection" on it will record the continuous movement of person for however long they are in camera view. With "motion detection" on it will also record traffic and birds etc so I perfer to just have it on "person recording". However I need to to continuously record the person as long as they are in camera view. How can I set it up to do this with only "person detection" enabled? I can't find anything in the settings to adjust the length of time the camera will record for when a person is detected.
