@SJH Try checking the Motion Frequency if you have a battery operated Camera. The default setting is Regularly, but you may want to change it to Frequently to better fit your preferences and to ensure you receive a notification for all motions that your Camera detects. You can also try adjusting the Motion Zones to make sure they cover the areas you need.
