Sorry, the text was translated with the help of the Google translator.

The problem is as follows: there is Zoneminder v. 1.34.21, which has 70 cameras. The image quality in "Montage rewiev" mode is poor and cameras drop out periodically.
Server:
CPU: Intel (R) Xeon (R) CPU E5405 8 * 2.00GHz
Memory: 32 GB
No video cards.

Please advise what can be adjusted. Thank you.

Sounds like you underspeced your server. Either add another server, or upgrade the hardware.

If you search around there may be some more tips on optimization. I thought there was a thread specific to montage recently, but regardless, there are always ways to lower CPU usage. See https://wiki.zoneminder.com/Dummies_Guide

First, lower the frame rate and resolution. 5 FPS at 640x480 or something like that. Yes, I know you invested in the high res cams but Zoneminder is not a 42 FPS movie camera system. And you can catch crooks at 5 FPS! Get it stable and push the settings higher to see waht happens.
If you want to continually monitor groups of cameras, set up a web page to show the cameras you want on a group and feed those web pages from Zoneminder. Can provide the code if needed.
