I have had 4 cameras since early 2015 and have not had any problems. I did replace two of them with different focal length cameras a few years ago. I have been using Netcam Studio for live viewing and IPTimelapse for making time lapses. This morning at 5:30 I updated Windows and restarted everything. Things were working just fine until 6:58. I was watching all four cams on Netcam Studio when all 4 cameras lost connection and couldn't reconnect. I checked IPTimelapse and all cameras quit at 6:58 there. All cameras are connected to router via PoE injectors (individual). I have tried the SADP Tool and it cannot find them. Any help would be appreciated.

If you ping the individual camera's do they reply?
 
When you power them back up, do you hear a click (the IR filter) and can you see the red infrared if it is dark out or you can cover it?
 
It might help to provide a network topology diagram showing your devices and IP addresses. And you just may find the issue doing this. Perhaps you had the computer or cameras on DHCP instead of a static address and now they are different IP addresses than what you think they are due to updates and rebooting?

You can list the private LAN IP addresses as it does not tell anyone anything - they are the same as everyone else. The IP address of your service provider for your WAN is what you don't provide...Everything on the inside past the modem is fine to put out. Everything on the inside, the local will fall under these ranges and you are not telling anyone anything about how to hack your system providing these ranges (basically any IP that starts out 10. or 172. or 192. are reserved for the "home side" of the service so every home internally will be within this same range):

10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255
 
What about using the Hikvision SADP tool to see if there are on the network.

this happened to me a few months ago with hikvision cameras I got off Amazon, they were just bricked
 
Two of the cameras are about 25 feet in the air. The other two are readily accessible, but in the middle of a blizzard right now. All four cameras were set to static IP addresses.
192.168.1.208
192.168.1.206
192.168.1.76
192.168.1.205

I was actually watching all four cameras on the computer when they went down. Seems strange that they would all go at once.

what is your ip? not wan just lan
 
Each camera has its own individual PoE Injector and all lights are green.

To rule out a POE issue if you have a 12 VDC PSU power one of the camera's that way. If the camera doesn't show any signs of turning on and activating (IR Clicking) there's obviously a hardware issue. Ideally one camera would be removed and inspected and connected with a new ethernet cable and powered by 12 VDC.

Doing so will affirm the hardware is fine vs not . . .
 
Do these cameras have a IR light? Tonight can you tell if the IR lights are on, then you can rule out power and then this might be a network / firmware issue
 
Also have you power cycled the POE injectors?
 
My LAN is 192.168.1.101
Only two of them had the IR set to automatic. I will check to see if they come on when it gets dark out.
I have power cycled the PoE Injectors and the router.
 
now please check your firewall setting and your router to make sure the cameras are not blocked
 
^That is a very real possibility that the Windows update changed the firewall settings.

Good point. Log into your router and look at what it sees as being on the network. It should show up there. From what you are saying you lost this after an update on your PC, then I would look at your PC. Do you have another PC on the network you can try to ping the cameras?
