Advice on integrating a camera into my Lovelace build

I’m attempting to replace my MQTT based tablet dashboard with a Lovelace one that has a high WAF. I dashboard I’m trying to replaced is shown below.

I’ve started to build out a tab using the custom:bignumber-card (for the date/time) and primarily the custom:button-card as both allow me to scale the icons and the latter allows for the card/icon to flash which is a mandatory requirement.

My initial question is, what’s the best way to add a surveillance camera that would allow me to scale the card size to match the others? At the moment, I’m using a simple picture-entity.
