 Run Kerberos Agent with [Balena Cloud](https://www.balena.io/) super powers. Monitor your Kerberos Agent with seamless remote access, over the air updates, an encrypted public `https` endpoint and many more. Checkout our application `video-surveillance` on [Balena Hub](https://hub.balena.io/apps/2064752/video-surveillance), and create your first or fleet of Kerberos Agent(s).

 By default your Kerberos Agents will store all its configuration and recordings inside the container. To help you automate and have a more consistent data governance, you can attach volumes to configure and persist data of your Kerberos Agents, and/or configure each Kerberos Agent through environment variables.

-The idea of blocks, you can find a more thorough explanation [here](https://docs.balena.io/learn/develop/blocks/), is that you can compose and combine multiple `blocks` to level up to the concept an `app`.

+Next to building individual `blocks` you as a developer can also decide to build up an application, composed of one or more `blocks` or third-party containers, and publish it as an `app` to the Balena Hub. This is exactly [what we've done..](https://hub.balena.io/apps/2064752/video-surveillance)

+On Balena Hub we have created the []`video-surveillance` application](https://hub.balena.io/apps/2064752/video-surveillance) that utilises the [Kerberos Agent `block`](https://hub.balena.io/blocks/2064662/agent). The idea of this application is that utilises the foundation of our Kerberos Agent, but that it might include more `blocks` over time to increase and improve functionalities from other community projects.
