On my new raspberry Pi 4 I have just 2 programs running 24/7. One is CumulusMX weather station, and the other is Xeoma CCTV camera program with 4 cameras running.
Due to a couple of minor niggles with Xeoma on the Pi, I checked the cpu usage and it is getting on for 90%, which I know is high.
Is there anyway I can reduce this figure, and still keep the 2 programs.
run 'top' in a console session to see what's eating your cycles. My guess would be the cameras

Switch to mjpeg, if your cameras support it?
Thanks, that helped plus making a couple of changes to reduce cpu load, which now around 12% to 16% with around 80% idle.
Unless you had it WELL ventilated, there is also the chance that it was throttling back due to overheating. That would exacerbate the issue.
The Pi is in a an acrylic case with a fan and heatsinks on the cpu and other parts, and it feels cool to the touch. It was the actual camera software where I made the changes.
