- Dove 14y agoMy dad was using a powder-actuated concrete nail gun for some remodeling not long ago. It used .22 loads to drive nails. The sound it made was eerily identical to the real thing.
- kijin 14y agoThe system will have to distinguish real firearms from other powder-actuated hardware. Otherwise it's going to become useless anywhere near a construction site. But what if you shoot a person with a nail gun?
- ComputerGuru 14y ago> But what if you shoot a person with a nail gun? What if you stab a person with a knife? It's off-topic. It was designed and built to detect gunshots from real guns.
- Dove 14y agoI think the best way to distinguish between firearms and nail guns would be with a man in the loop listening to the sounds (which they appear to have). Construction doesn't sound like a firefight.
- Jabbles 14y agoWouldn't it make more sense to make the alarm send out a standardised frequency a la DTMF tones?
