I have 6 cameras, all set to 1280x720@10FPS. Montage mode works great, except that I can't get out of it. I'll select Console, and I'll never get there. I have to kill nph-zms manually. During montage, load goes up a bit, nit much, and nph-zms takes 15-25% cpu.
If I only view 3 cameras at a time, exiting takes awhile, but works.
Any ideas?
