I recently revisited a (former customer's) surveillance system that I designed and installed a few years ago. The customer had asked if I would (informally) 'check out' and diagnose a 'jittery camera'.
I sat down at the VMS and found things all out of sorts. The 'jittery camera' was that way because someone had reconfigured it for streaming at 1FPS. I corrected this, and the customer was really happy.
However, as I dug deeper, I found tons of problems with the configuration. Half the cameras were now recording MJPEG, (system storage was designed using H.264) most were recording at 30FPS (totally not needed), some were streaming at 640 X 480 despite being 720P cameras, and someone had monkeyed with shutter speeds for no apparent benefit at all. I recommended the customer take control of passwords and accounts for cameras and VMS, since it appeared to be a free-for-all.
The customer told me that the only problem they really had was the 'jittery camera', and they were fine with all the other sub-optimal settings and while they appreciated it, I did not really need to change anything else.
They also told me I was way too picky about things and just kind of laughed about the mess things were in.
If you were me, how would have you responded? Have you faced similar situations?
