Q: Anyone have a photo of the "bracket" used to mount it to the wall?

Thank you for reaching out to STI. Visit this link to view the install which shows how the unit is mounted and it's hardware specifically the H19020 clamp https://www.sti-usa.com/wp-content/uploads/9618Install.pdf Tech support can be reached at support@sti-usa.com.

Q: Does this cover have a lock? Can it be opened to replace battery in the motion detector?

This product does not have a hinge or a lock. I used two hard plastic cable clamps on the left side of the cage, to mimic a hinge. And, I added a hasp (3", from memory) to the wall on the right side and used a master lock to loop thru the hasp and the cage, so I can change batteries (without needing to remove screws). ((Beware, STI charged me a restocking fee for another cage I returned, even though there was a 100% refund policy..., so you might look for an alternative product from a more above-the-board company that stands behind their return policy.))

Q: how does it get mounted?

It comes with brackets & screws.

Q: Will this work with an Arlo camera?

STI manufactures wire cages specific for cameras, the best way to determine the correct cage would be with your dimensions H x W x D, visit this link to view our options https://www.sti-usa.com/series/cctv-guard/.
