# In a Wired article it is mentioned you have now refined the Sentry system to a 95 percent precision prediction rate. How many civilians in total do you estimate you have saved to date?

The remote sensors can distinguish aircraft with 95% accuracy at optimal range. It’s harder to measure exactly what’s happening on the ground in Syria, but we have compelling data that suggests the presence of Sentry and remotely operated air raid sirens can reduce the lethality of airstrikes by up to 27% in areas of heavy bombardment.
