Hi,
1. The Tapo C310 V1 does not support vehicle and pet detection, so you can't find them on the Tapo app > Camera's Device Settings > Detection page.

2. Have you inserted an SD card into the camera to store video recordings?

3. The problem is related to the camera settings and the actual actions that triggered the notifications, please help confirm:
    1) Send us a picture of the camera's Device Settings > Detection page.
    2) Send us the pictures of the enabled detection types.
    3) Please help to record the event manually on the camera's live view page, which shows the event shouldn't trigger a notification.

Best Regards

Hi,
The raindrops are huge on the camera's live view page maybe because it's very close to the camera's lens.

The basic camera's detection mechanism is based on image changes between different frames. The frame is one of the many still images which compose the complete moving picture. If there is a difference between the frames, the camera will recognize it as a motion detected. When it rains, the raindrops will cause a significant change in the image, therefore this kind of detection cannot be avoided.

You can refer to the instructions below to reduce motion detections from rain.
How to reduce motion detections from rain, snow or insects, etc

Btw, you can upload the video to your cloud server(such as Google Drive), generate a link to download it, and send the link to me via a private message.

Hi,
1. For the feature request to add an activity zone for the Person Detection feature, I'll log it and forward it to the relevant team to evaluate.

2. The Line Crossing Detection feature works for the person and object crossing the line, not only for the person. It's normal to receive a notification when a cat crosses the line.
