Verkada access controllers can use local connections to communicate directly with other Verkada devices over their shared local area network (LAN). Local connections allow cross-device features to continue to operate even if they lose their connection to the Verkada cloud.
Note: When a Verkada access controller is offline, local connections only apply to the operation of the access controller’s cross-device configurations. See Verkada Access Offline Operation for information on access controller offline behavior without local connections.
How cross-device local connections work
Verkada access controllers automatically establish local connections with relevant devices when you configure cross-device features that support local connections.
Note: The devices an access controller establishes a local connection with depends on the type of cross-device feature.
For LPR Unlock, the access controller establishes a local connection with an LPR camera.
For AUX inputs/outputs (I/O), the access controller establishes a local connection with other Verkada access controllers.
Devices communicate via local connections by default (when available) because local connections are generally faster than cloud connections.
If one or both of the devices with a local connection lose their cloud connection, any relevant device connections continue to operate as long as they both still have a local connection.
Supported cross-device features
Déverrouillage par reconnaissance de plaque d’immatriculation (LPR)
LPR unlock allows a Verkada access controller to grant access to an entrance based on license plates recognized by a Verkada LPR camera.
An access controller establishes a local connection with an LPR camera over their shared LAN to exchange information about detected license plates for granting or rejecting access to an entrance.
Remarque : pour plus d'informations, consultez la section Configurer la reconnaissance des plaques d'immatriculation.
AUX inputs
AUX inputs can unlock doors when a device wired into the AUX input is triggered, such as a third-party intercom or button.
AUX inputs can unlock doors controlled by access controllers (other than the one where the AUX input is physically located) by establishing a local connection between the two controllers. For example, you can use AUX inputs on a Verkada AX11 I/O controller to unlock doors wired to a Verkada AC42 or AC62.
Note: See Unlock a Door from a 3rd-Party Intercom System or Button for more information.
Sorties AUX
AUX outputs can activate or deactivate based on various access events.
AUX outputs can respond to events originating from access controllers (other than the one where the AUX output is physically located) by establishing a local connection between the two controllers. For example, you can use a door forced open (DFO) event on one access controller to activate an AUX output on another access controller.
Note: See Configure an AUX Output on an Access Controller for more information.
Vérifier l’état de la connexion locale
Déverrouillage LPR
Navigate to the door configured for LPR unlock.
If the door's access controller has a local connection with the LPR camera, it should function as expected.
If the door's access controller loses its local connection to the LPR camera, the message LPR Camera Connection Degraded will display at the top of the camera feed.
AUX inputs and outputs
A Device Connections icon
indicates a local connection is established between two access controllers. You can find the icon in the following places:
On the AUX I/O page.
On the Access > Doors page where the AUX output is listed.
On the Access Controller page, where the AUX output is listed.
Click
to display the cross-device connections.
Under Connection Status, you can see the current cross-device connection status. See the connection status table for more detailed descriptions.
Under Connections, you can see the connection status for each device connected to the AUX I/O. There are 2 connection statuses:
Cloud
: connection between the AUX I/O's access controller and the other access controller through the Verkada cloud.
Local
: connection between the AUX i I/O's access controller and the other access controller through their shared LAN.
État de la connexion
État | Description |
Appareils entièrement connectés | Cloud and local connections are available between the AUX I/O's access controller and all other relevant access controllers. |
Problèmes de connexion de l’appareil | Some relevant access controllers are disconnected from the AUX I/O either over the cloud or the LAN. |
Certains appareils sont complètement déconnectés | Some relevant access controllers are disconnected from the AUX I/O'S access controller over both the cloud and the LAN. The AUX I/O is not working correctly and the issues with the cloud or local connection must be resolved. |
Note: AUX inputs and outputs with cross-device configurations continue to operate without a local connection by using a cloud connection as a fallback (if one is available).
Résoudre les problèmes de connexion locale
Quels ports sont utilisés pour les connexions locales entre appareils ?
Les appareils Verkada utilisent les ports suivants pour les connexions locales entre appareils :
50000-60000: Les connexions WebRTC ont choisi un port de cette plage pour les nouvelles connexions.
5353: Port par défaut pour le DNS multicast (mDNS).
4929: Serveur HTTPS annoncé localement par les terminaux.
What if 2 devices cannot establish or lose a local connection?
Vérifiez que les deux appareils Verkada sont sous tension et connectés au même réseau local.
Vérifiez que le réseau local n’est pas configuré de manière à bloquer la communication entre les périphériques via les ports utilisés pour les connexions locales (voir les ports spécifiques ci-dessus).
Que se passe-t-il si 2 appareils avec une connexion locale perdent leur connexion cloud ?
As long as there is still a local connection, devices with cross-device configurations continue to operate without a cloud connection.
If the local connection is lost:
Confirm that devices can connect to the internet.
Check the network settings and confirm they have not been changed to prevent cloud communication. See Access Control Network Settings for more information.

Que se passe-t-il si 2 appareils sont complètement déconnectés (pas de connexion cloud ou locale) ?
Devices with cross-device configurations will not operate correctly without a cloud or local connection.
To restore operation and to resolve the issues with cloud or local connection, follow these troubleshooting steps:
