Multiple DVR's

[1946Dinosaur]

Hi All
I volunteer at a Museum in which I am using Deskreen for security cameras.
There are 3 x 16 port DVR's in 3 locations on which I use the HDMI out, into a HDMI Splitter with one leg to a monitor and the other to a USB Video capture device. So each DVR is visible on the local monitor and the three DVR's are about 150 meters apart.
At each location I have a Windows 10 PC with two Monitors attached to two HDMI ports. Together with the direct connect monitor means I have 3 monitors at each location.
I also have Deskreen, Chrome browser and VLC on each PC.
By "casting" the USB capture, the DVR's are visible using Chrome at all the other locations.
Once that is set up, I open two Chrome windows on each PC and use the two attached monitors to display two other DVR's.
So, now I have 3 monitors in each location showing all 3 DVR's.

That works well.
The only downside is that whenever there is a power failure or the Wifi has a hick-up, I have to reset all the IP addresses.
I have worn out a pair of shoes going back/forth with a notepad writing down the IP's, then keying it in Chrome, then going back and confirming at the source end.
I would dearly love to have FIXED IP addresses, so that when the PC's reboot, I can set up the connection at each point with one visit only.
Alternatively allow the re-connection on the same IP if it gets disconnected and then connected again.

Regards
PS: I have a pdf diagram if someone is interested.

Hi All
After the overwhelming response, I am taking the liberty to share my answer to this problem, but it doesn't involve Deskreen.
On each computer install VLC , X11vnc and Tigervnc. (Using Debian Linux)
Also each PC has Video capture to usb port.

Firstly on each PC
Open a VLC window by selecting the Video capture device.
Run x11vnc and select the open Vlc window.

Then on each PC in turn open Tigervnc and connect to the IP:port of another PC.
In the end each PC will have 3 windows , one of it's own and two of the others.
Minimize it's own and move one of the others to the second monitor.

So now each PC has 3 monitors (it's own on a hdmi splitter) and the remote two on 2 monitors.

If you use the same resolution on each monitor, then all screens maximize nicely.

Hope someone finds this useful.
