Configuring Video Motion Detection

Configure Video Motion Detection (VMD) settings for a video device

Video Motion Detection (VMD) is a method of identifying motion without the use of a motion detector. Cameras with VMD use software to determine if there is motion in the images they are capturing based on changes in the light and color of the video’s pixels.There is not a PIR motion detector built into cameras, but when VMD is set up correctly, it can be an effective way to capture activity and generate notifications for the customer.


Configure VMD settings


  1. Log into the Customer Website.
  2. Click Video.
  3. Click Settings.
  4. Select the desired camera from the Video Device dropdown menu.
  5. Click Video Motion Detection.
  6. For each VMD window:
    1. In Choose a VMD Window, click the number of the VMD window.
    2. Drag across the live view to draw the VMD window’s dimensions.
    3. Using the Sensitivity dropdown menu, select the desired sensitivity of the window.
    4. Using the Target Size dropdown menu, select the desired target size of the window.
  7. Verify the VMD settings are configured as desired.
  8. Tap Save.


Configure VMD recording schedules


  1. Log into the Customer Website.
  2. Click Video.
  3. Click Recording Schedules.
  4. Click + Add Schedule.
  5. Click to select Video Motion Detection (VMD).
  6. Enter a name for the recording schedule.
  7. Select which camera records when it detects motion, as well as the time frame and minimum delay between camera-triggered clip uploads.
  8. If desired, click to select the At home settings. The options include:
    • Do not record when the system is Disarmed.
    • Do not record when the system is Armed Stay.
    • Do not record when any of the Geo-Devices are inside Geo-Fence.
  9. In Video Clip Recipients, click + Add Recipient if the user wants to receive notifications.
    1. Click to select the entries in the Address book to be notified, or click + New to add a new Address Book entry.
    2. Click Close.
  10. Verify the recording schedule is configured with the desired settings.
  11. Click Save Schedule.


Video Motion Detection (VMD) best practices:

The window sizes and locations, in collaboration with sensitivity and target size, can help if a customer is receiving many false clips due to a camera recording too often or not often enough.


Window locations and sizes

A video device’s VMD windows work best when drawn like trip wires. Set up longer and narrower boxes in areas where motion would be of interest to the customer.

Avoid placing VMD windows in highly dynamic areas, such as trees and bushes (which can move due to wind), large reflective surfaces, or large areas where shadows could be cast. Remember to think about how the lighting may change throughout the day. An area that was not shaded may become shaded later in the day.

Important: VMD windows should not overlap. Overlapping VMD windows can lead to false triggers and unwanted recordings.

Target size

Target size is the percentage of the window that includes movement to trigger a clip recording.

If the target size is too large, the camera may not trigger for anything less than an object the size of a car. If the target size is too small, leaves blowing in the wind may trigger recordings.

Estimate the percentage of a window that a the desired trigger would fill (person, car, animal, etc.) and then select one size larger. For example, in the image below, if one of the chairs was the same size as a person, that person would take up about 15% of the window. Therefore, when selecting the target size, we should select 20%. That percentage would pick up a person, but will most likely not pick up any stray shadows.




Sensitivity is a measure of how drastic a change is needed to trigger a clip. Higher sensitivity means a smaller shift in the video is needed to trigger a clip. If the sensitivity is too high, the camera may trigger constantly.

Typically, you should start with a sensitivity of 7 and fine-tune from there. If the sensitivity needs to be maxed at 10, then your window placement, size, and target size most likely need to be adjusted.


Note: For camera models ADC-V521IR, ADC-V522IR, and ADC-V722W, the sensitivity setting affects all Video Motion Detection (VMD) windows for the specific device.


At-home settings

At-home settings, when enabled, pause recording schedules when the system is disarmed, armed stay, or a Geo-Device is inside of the Home Geo-Fence. This can help prevent unwanted or unnecessary recording.

Key Points:

Rather than creating one large, imprecise box, try creating lines or barriers. The goal is to catch a person of interest as they cross through the window.
