Tailgating refers to the act of waiting for an authorized user to open a door, and slipping in behind them to gain unauthorized access to a building. For most organizations, this poses a major security risk.
Through Verkada's tailgate detection feature, your organization can easily identify this behavior. Native camera integration allows for automated security monitoring with AI and ML applications to detect tailgating, crowds, and more.
With integrated video security and access control, Verkada leverages data from door events and edge-based video analytics to produce an accurate people count. If multiple people enter a doorway through one access grant, the system raises an event and flags it as tailgating.
How it works
Tailgating events populate in Verkada Command, along with all other door events, enabling more proactive protection of people and assets.
Verkada’s tailgating implementation does not require any new hardware. As long as you have a Verkada camera paired with an access controlled door, you can enable this software feature through Command.
Requirements for camera mounting
Inside camera—Mount the camera on the inside of the door (opposite of the reader) such that people will walk towards the camera after badging in.
Camera height—Place the camera higher than the top of the door frame.
Camera field of view (FOV)—Leave a gap between the bottom of the door frame and the edge of camera's FOV.
Camera angle—Position the camera angle between 10° and 55° relative to the perpendicular axis (measured when looking directly at the door).
Max Distance from Door—For optimal results, refer to this table to place the maximum distance the cameras from the door.
Camera Model | Max Distance from Door |
42 ft (12.8m) | |
39 ft (11.8m) | |
50 ft (15.2m) | |
43 ft (13.1m) | |
62 ft (18.8m) | |
105 ft (32m) | |
140 ft (42.6m) | |
42 ft (12.8m) |
Configure tailgate detection
Required. A DPI must be installed on the door and enabled in the settings in order to configure tailgating detection.
In Verkada Command, go to All Products > Access Control.
Select the door you want to enable tailgating.
Click Settings.
Under Pairing Cameras:
When prompted for setup, verify the camera is mounted according to the recommended settings on the first page, and click Next.
On the next page, highlight the door in the grid, ensuring that the door takes up at least 80% of the frame, and then click Done.
If tailgating is detected, the event will populate in Command within 3 minutes.
