Processor usage spiking every minute

hey all
I’m new to home assistant recently getting a home assistant green (which i know probably isn’t the most powerful just wanted a nice entry level plug and play) i have been tweaking it for a few weeks now adding devices and such and have recently noticed that the processor chart spikes every minute or so assuming this isnt the normal state of home assistant i was wondering if anyone would be able to help me narrow down what might be causing this? (my root suspicion is the reolink cameras i have connected and hooked up to frigate and streaming a live view through rtsp but i am unsure as i dont have much knowledge on the direct ins and outs of how things run)

here are a few images of the chart if anyone has any ways to help me at least narrow down to see what’s doing this i would greatly appreciate it
