Try lowering the capture FPS on all the monitors (works better to lower it on the camera end, then leaving blank the fields in ZM). Also, you could increase the buffer size, as stated in the messages.

Thanks For your Reply Bro

Can you please let me know where i can lowering the capture FPS (what is FPS) please tell me where i can increase the buffer size please tell me the path it will really helpful for me

Many Many thanks in Advance

Frames per Second, and you want to look in the webgui of your camera interface to find it, 5fps is plenty

Hi,

Under each monitor configuration you will find the fields you are looking for. In the General tab:
Maximum FPS (?): leave it blank
Alarm Maximum FPS (?): leave it blank

Then click the Buffers tab and set these values (orientative only for testing purposes, then you may need to addapt it to your needs)
Image Buffer Size (frames) : 250
Warmup Frames: 50
Pre Event Image Count: 50
Post Event Image Count: 75
Stream Replay Image Buffer: 1000
Alarm Frame Count: 3

Remember to save the configuration of the monitor and then restart Zoneminder. I would also set all the monitors except one to Monitor mode, in order to determine which configuration of buffers works better four your setup, then do the same for each monitor. Be sure that you have enough RAM for the shared memory.

Hope it helps,

PacoLM

Thanks For your reply bro
i saw my cemeras settings webgui here its showing three settings below:
1.Analysis FPS
2. Maximum FPS (?)
3. Alarm Maximum FPS (?)

Can you please tell me which one i need to change

[PacoLM]

Leave all of them empty

[SteveGilvarry]

I was talking about on the camera you control the number of frames per second, FPS, not in zoneminder interface. Follow PacoLM's advice on those fields in ZM.
