How to I create a back-up motion sensors?

So, I have several critical areas that I would like to have at lease two motion sensors detecting. One is my front drive. Having two sensors I'm less likely to miss a trigger if one has a low battery, sun hitting it...etc.

Rather than setting two duplicate triggers and therefore getting two separate actions (video clips/photos/alerts) how does one create one action from two triggers (being either of the two motions senors detecting motion)?

Thank you!

Trigger on a variable and have the motion sensors set the variable?

Create a virtual device group made up of multiple sensors and have your triggers watch for changes to the virtual device group.

So, for example, I have this:

Virtual Device Group, I'll give that a try... thanks!
