There are some other interesting threads where users have tried to parse out all their Always On devices. Here’s one.
Your number looks a bit high for the set of devices you list, though cameras have huge variation depending on resolution, technology and lighting capabilities. I have a larger number of Always On devices, but a lower power draw (360W). I recently made the the decision to pull my stereo receiver off a timer (it may have contributed to the digital board blowing out), added Sonos Amp, plus have halted nighttime shutdowns of my primary PC. That took me from 340W to 360W.
