Hello Everyone,

I have everything working perfectly now except one minor detail. When I play back an event the video will show a few initail images walking, then have a gap in the video and then it seems to go into super fast motion.

ex. Someone walks in the door the camera will capture them taking a few steps, on the next frame they are a noticeable distance from the previous frame and then go into supersonic speed.

Is this a buffer setting or frame setting that is set too low to capture all the action or is something else going on.

Thanks
John

this is "i think"cuz the frames now are stored in diferent way on the database. so there is no timming if you set camera to Ex. 2fps when the camera can go to 10fps so the 10 first frame will be recorded at 2fps and the "alarm" frames will recorded at 10 fps. or something like that

I think you might be on the right lines Fernando but there's a bit more too it. Firstly you need to check whether you have a maximum FPS setting on a camera. If you do then if you also have ZM_NO_MAX_FPS_ON_ALARM set to on (in Options->Config) then ZM will ignore the max FPS setting if you get an event, thus as Fernando described you might get the first few frames at 2fps and then the rest at 10fps. If you have ZM_VIDEO_TIMED_FRAMES on (Options->Video) then this should be taken into account. It may be worth checking and experimenting with these settings to see if any make any difference. One other thing you can check is the actual frame timings themselves. If you click on the Frames or AlarmFrames value of an event from the event list you will get a table up containing information about each frame, this includes a time delta. It's probably worth checking that to see if it looks sensible as well.

Phil,

Thanks,

You both have given me several things to check. I will look into and let you know what I find and if it solves my problem.
