Video doorbell 2nd gen missing beginning of recording

The first several seconds are generally missing from my recordings. For example, when I walk to my front door, my video begins with me opening the front door. Doesn't show me walking up which, depending on the direction I'm coming from, could be five seconds worth of recording. Then the recording ends after about five seconds because I'm no longer in the frame. So you see the person walking into my house for less than a second. This is how most of my videos are. This makes the recording useless because if I was there to do harm, I'm not on camera long enough to see what I look like. Is this the norm? Thanks
