Notice: Beginning February 2023, newly created video accounts will no longer have the option to create VMD recording rules. This change comes as Alarm.com confidently moves forward with Video Analytics as the premier motion recording solution. This change will not affect any accounts created prior to this date. Alarm.com camera models that support VMD recording will continue to be able to use VMD recording rules after the cutoff date.

Tips and Best Practices
Window Locations and Sizes
A video device's VMD windows works best if you position them like a tripwire. Create long, narrow boxes in areas that must be passed through to reach the area of interest. Keep in mind that it is recommended to avoid placing VMD windows in highly dynamic areas like large reflective surfaces, large areas where shadows often move, or trees and bushes that move due to wind.
Examples of correctly placed VMD windows:

Target Size
The target size setting is the percentage of the window that observes movement to trigger a recorded clip. If the target size is too large, the camera may not trigger for anything less than the size of a car. If the target size is too small, leaves blowing in the wind may trigger recordings. It is recommended to estimage the percentage or a window that a person (or whatever you are wanting to record) would fill, then select one size larger.
Sensitivity
The sensitivity settings is a measure of how drastic the movement is to trigger a recorded clip. The higher the sensitivity, the less motion is needed to trigger a clip. If the sensitivity is too high, the camera may trigger constantly. Note, for the ADC-V521IR, ADC-V522IR, and ADC-V722W models, the sensitivity setting affects all VMD windows for the specific device.
At-Home Settings
When enabled, the at-home settings pause recording rules when the system is disarmed, or a Geo-Device is inside the Home Geo-Fence. This can help prevent unwanted or unnecessary recordings.
