Graffiti detection system coming to Hanford

Now they hope a small black box, called the Merlin Graffiti Detection Sensor -- will help them.

The device works partly by detecting traces of aerosol spray, and notifying officers with a wireless transmitter.

The silent alarm means officers can immediately respond while the vandals may still be in the area.

Capt. Parker Sever said, "We're hoping it will deter them and now they know they're there we hope it'll deter them from being involved in this activity."

Officers hope to have two of the graffiti detectors installed in Hanford by early next year.
