[GA] [SFH] Experience with speed cameras?

Can anyone share their experiences as a board member with speed cameras and if it corrected the speeding issues your community had? We are not looking at this for revenue and will likely issue warnings for the first violations, followed by suspending the gate decal for the household, etc. Our core concern is stopping the dangerous speeding where kids are playing.

We are considering the Traffic Logix Guardian Pro. If you have other devices that worked well we would love to hear about those as well.
