Screen recording attached.

Device details -

C320WS records continuously to H200 hub, no memory card in the camera itself. Camera connects to H200 wireless, H200 connects to router wireless. Both signal strengths are at around -60 RSSI. Vehicle detection is ON.

1. As you can see in the bottom thumbnail (time stamp 6:04:01) of the playback tab in the Tapo app, the vehicle in the thumbnail does not show up in the video on clicking that thumbnail (6:04:01). In fact, that vehicle only shows up on video when I manually set the time of the video playback to a few seconds before 6:04:01 as seen in the video. I think this might be because in this instance the camera detected the object as a vehicle late. But the thumbnail has the vehicle!

2. Another problem is that the car recorded seems to fast forward in the middle of the recording. This fast forwarding can be seen in other recordings as well from this camera. 

Is there any setting i can change to improve these two issues? 

Thanks!
