Smoke Detector / Fire Alarm ?

[jrwpmw]

Hi, I'm new! I just received my Amcrest NVR and will be setting it up soon. I had a related question, are there any smoke detectors/fire alarms that will integrate with my NVR? I searched Amcrest products and didn't see anything, looking online I really didn't see anything either that might work (most hits were for fake smoke detectors with a camera). Thanks in advance for your help,

I would like to know about this smoke detector. Is there any app available?
