IP Cams freeze after awhile

I have a dedicated tower to control my IP cams with ManyCam Studio v7.7.1.2

Processor: Intel® Core™ i7-3770 CPU @ 3.40GHz 3.40 GHz
Installed RAM: 10.0 GB (9.87 GB usable)
System type: 64-bit operating system, x64-based processor

The system is set to performance settings on Windows 10 Pro.

I have 7 (one USB and six IP Cams) cams set up on ManyCam using the motion detect to switch the screen to the active cam. After awhile (time unknown) I notice the cams freeze. They will no longer switch to the active cam. I have to either right click on that cam and re-add it, or shut down and re-load ManyCam to get them all working again. This is getting very frustrating.

Can I get any help with this?

Thank you.
