I have an Axis Q6035-E camera. Overall I like the camera but the PTZ response time with Milestone SmartClient is about 2 seconds (it takes 2 seconds after I click the mouse before the camera pans or zooms). Using the web interface to the camera (bypassing Milestone) the PTZ response time is about .25 seconds.
I have an older JVC camera and it's PTZ response time is about .25 seconds.
From a usability point of view the .25 seconds is fine. The 2 second delay makes it difficult to follow a suspect. I'm not sure if there is an industry standard or target response time for an IP camera using PTZ control. If not perhaps IPVM should rate and try to set one.
I realize that the Milestone Client will buffer several frames to make the video appear smoother. I tried lowering it to 1/4 second and raising it to 2 seconds, didn't seem to make much difference. My server is running 30-50% CPU utilization. So I'm not sure where the problem is. I suspect using Milestone as the inbetween is just adding some delay. I haven't researched any possible issues with the various Milestone's device pack (camera driver) versions yet.
I'd appreciate any insights into this issue. Is my experience typical, thus I just have to live with it. Or do you think there is a technical issue with the Axis camera or Milestone VMS system?
