## Questions & Answers

**Q: Anyone have a photo of the "bracket" used to mount it to the wall?**
A: 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?**
A: 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?**
A: It comes with brackets & screws.

**Q: Will this work with an Arlo camera?**
A: 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/.
