## Questions & Answers

**Q: How does it open for servicing unit?**
A: Hello, Thank you for reaching out to STI.  The STI-9614 will need to be removed from it's surface to maintenance units underneath.

**Q: Do you have any troubles in the night with the light sensor of your cameras? I mean, are able to record outside the cage?**
A: I cut a hole in the cage just large enough for the camera face to line up with the edge of the cage so the camera can record properly at night.

**Q: Will a Arlo camera and wall mount fit inside?**
A: Yes. Will mount anywhere on a flat surface.

**Q: Does this have a heat resistance rating? Could it be used in conjunction with a 150w heat lamp?**
A: Hello,
Thank you for reaching out to STI.
These have not been tested with heat they are meant to protect a beacon and sounder.  They are made of heavy gauge coated steel.

### ⭐⭐⭐⭐⭐ 







  
  
    Protect life saving smoke detectors from idiots.
  

*by C***N on Reviewed in Canada on 5 July 2023*

Despite the smoke detector "hush" feature, tenants disconnect detectors from time to time for reasons such as someone burning toast, engaging in cigarette/pot smoking, or vaping. The grill prevents tampering, or at least gives morons pause to consider the seriousness of their stupidity.

### ⭐⭐⭐⭐⭐ 







  
  
    Nicely manufactured
  

*by T***D on Reviewed in the United States on 17 May 2022*

Works exactly as intended. Keeps kids in a gym from damaging my radon monitor
