Step-by-step guide on how to obtain video data from any Howen device via API.

To connect your tracker using the Howen protocol, you need to create a howen channel first.

Point your MDVR to the channel's domain name:port via the Howen iTool mobile app provided by the vendor. Don’t forget to select ‘H-Protocol’ to allow the connection to a server.

Create a device instance for your tracker, using the serial number or the 'ident' value (look up in the channel's Logs & Messages) to fill in the ‘Serial Number as ident’ field.

Use the Logs & Messages tab on the device screen to check if the messages are coming.

Get access and manage your media in the dashboard and via API.

To ensure that video features work properly, please verify that the timezone set on the device matches that cached in the Clock settings.

If the timezone differs, simply refresh that setting (red circle icon) when your device is connected to the platform.
