It can be a parents worst fear, if you can't be there, who's watching your child in the pool?

"If kids are swimming in the water, the top of the water is moving its hard to see the bottom of the pool and this can do it," Chris Oldenburg with the Birmingham YMCA Youth Center says.  

He's talking about the Poseidon.

"People who go still in the water, it doesn't act as the lifeguard but it acts like the lifeguards third eye," Oldenburg says.  

Here's how it works, three cameras are in each corner of the pool and the technology detects when there is no motion.

Poseidon has been on duty at the Shelby County YMCA for almost a year.

Jennifer Dick with the Shelby County YMCA says, "It's a learned system so it takes sometime for it to learn."

Adults are breathing a sigh of relief for Poseidon.

"I think it's wonderful, I absolutely do. I was a lifeguard and safety is the up most importance to me," Karen Cefalu says.

And, the lifeguards here embrace the extra set of eyes.

"It never has a bad day, it's always alert and sometimes lifeguards have bad days and they may not be focused right on the pool and POSEIDON helps us stay alert and remind us that we have to do what we have to do," Lifeguard Ashlee Walters says.  

Ensuring a safe swimming season for adults and children, alike. Shelby County and the Birmingham Youth Center YMCAs are the first pools to receive a Poseidon in the state. The hope is to have Poseidon installed at all the local YMCA's in the near future.
