A protective wall in Red Bluff has become a virtual reality.
You can't see the so-called 'virtual fence,' but they can see you.
Security cameras and motion sensors are on 24 hours a day, seven days a week.
"Let's take it for example, somebody hops a fence in the middle of the night. Dispatch is going to be notified that somebody's in there. We have cameras to zoom in. Further, we can have our dispatcher get on and say 'you need to leave the park, the police are coming,'" said Red Bluff Police Sergeant Kevin Busekist.
The $21,500 project was approved by the city council last October.
Since the system was activated last week, officers have already utilized it in four incidents.
The Red Bluff Police Department says that they consider this to be a test case, with hopes that the city council will consider similar technology at other problem locations in the future.
