Pet Detection vey hit and miss - Indoor Pan and Tilt

Purchased the Indoor Pan and Tilt camera to use primarily for see what our dogs up to.

It seems to be very hit and miss, when the dc og walks past the camera in the bottom of the frame it doesn’t see it but when it’s at the back of the room middle of the frame and it lifts its head it detects it.

If I turn on other motion it picks it up every time but them it picks up everything.

I’ve tried all sensitivity settings but even on most its still hiss and miss.

How can I improve the Pet Detection and not have to enable other motion detection?

Any advice would be much appreciated.
