What is the range of fixed cameras?

Hey guys, sorry if this post is a bit confusing. I just get really paranoid around speed cameras. Basically I was going around 94-98km/h on the freeway and then within about 300-400m of this speed camera I accidentally sped up to 105km/h for less than 3 seconds, I immediately brought it down and went through the actual camera at about 80-82km/h. I was wondering if anyone knows the range of the speed camera or if anyone knows if it would’ve pinged me even tho I only sped up for a second or two accidentally.

Thanks! I’ve attached a photo of the camera and around about where i think I sped up.
