Swimming pool fencing works best when used in conjunction with other products.
In addition to all of the fencing and alarms on and around your swimming pool fence, consider an alarm on any windows leading to the pool area.
Make sure they are loud and distinctive to alert you when your child has potentially used one to get to the swimming pool area. Listen to the sounds of different alarms before you purchase one. Ask the retailer if there is a way to customize the alarm, change the volume or add features to make the alarm work best for your swimming pool area.
This is an added layer of protection, working with a swimming pool fence.
