Dramatic fire video was captured on a doorbell camera on Tuesday morning when a house ignited in the middle of the night on Jacksonville's Westside. The fire is being investigated as arson. 

Crews with the Jacksonville Fire and Rescue Department responded to the 5700 block of Sonora Drive around 3:30 a.m. to a residential structure fire. 

When they arrived, they saw heavy fire coming from the home. No injuries were reported as the home was vacant at the time of the fire.

At this time, we don't know how the fire started, but the State Marshal's Office is investigating it as arson.
