The default monitoring for a new camera stream detects people and cars using Matroid's Everyday Objects detector. You can change which objects are being detected in the monitoring settings, or make a new one with any detector that you'd like.
Because monitorings require credits, we provide 100,000 credits for the first successful registration of each kit. These credits - enough to monitor a stream for 3 days - are bound to the account on which you first registered the camera. To view your credit usage, click on your name in the upper right corner, select Account, then Credits.
