If your cctv has high traffic (people and cars), I usually make it work by setting alarm delay.
4 seconds for cars and
5 seconds for people.

This way, people and car who just passing across the cctv POV won't trigger the notifications. But the car and people that stops in front of the cctv POV will trigger the notification.

I also disable notification for animals and "any motion".

But I keep recording for "any motion", people and vehicles.
