hi guys,

ive got a hikvision NVR and 4 x hivision cameras, 3 bullets and 1 dome.

ive noticed when playing back the dome one, i get occasional frame drop.

tried various settings but nothing seems to fix it.

the cameras are plugged direct into the NVR poe ports.

any ideas what might cause this? i dont recall it happening, when i had 4 x bullets, but i replaced one bullet with a dome, with wider lens.

its a DS-7608NI-E2 NVR (8 port)
firmware: v.3.4.96 - build 170921

cameras are: 3 x DS-2CD2032-I (bullets) and 1 x DS-2CD2342WD-I (dome)

any ideas?
 
Have you tried lowering the FPS to 10 for example and the the iFrames to match. Also dropping the bitrate down to 4096 on the cameras.
 
funnily enough yes, im running 10FPS, and max bitrate is set to 4096 - it didnt help.
where are iFrame settings, camera themselves?
 
thanks yes, same place - and i tried exporting to pc, and it drops then too.

ive changed to CBR as above screen shot, and changed iframe to match fps

thanks all, i'll see how it goes

i read somewhere, that iframe should be double FPS - does that sound right?
