I tried it out last night and it's working fine. The only tricky part was that the default address of the camera is 192.168.0.20, and my subnet is not 0. The nice people in India told me to temporarily change the subnet on my computer to 0 and it was then able to talk to the camera. Everything is back to normal and the camera is on the correct subnet.
Motion detection worked fine but it captured several 8 minute videos between 5 and 6 AM when no one was in the litterbox. I think it was because of daylight coming up. I had to leave a bright light on in the bathroom or the cam doesn't see anything but daylight still seems to have had an impact.
I turned down the sensitivity a notch. Now I need to rig a light that will shine on the litterbox without disturbing the whole house at night. And I need to wall or ceiling mount the cam.

Thanks for the pointers; I'll feel much better if I can see that Espy is peeing and pooping. One of the videos last night had Espy pooping. Marlo peed twice. Nipsy apparently held it all in.
If I recall correctly, you connect up the cam on that address but then you change the cam address to .1 instead of .0 and then you change the subnet back on your LAN to it's default. That would be a better practice - change the device, not your LAN. The config page would be accessible using http://192.168.0.20 as your camera is configured now to go in and change the settings of it.
Glad to see you got it working, I love my TV-IP400W but I wired it to reduce the LAN bottleneck speed.
I've read your past posts and I can tell you that they mis-diagnosed my living cat (had two, one just passed) with the murmur thing once then the same vet did not hear it on future visits. I can tell you that they said I would likely see panting and lethargy if it became serious.

I'm a bit confused, Epsy is eating, peeing, pooping so is there still a problem?

Oh, I didn't leave the PC on the 0 subnet, I did change the camera and then changed the PC back. I actually use 12 instead of 0 or 1. I just figured that I should be different.
While Epsy is currently sort of eating, definitely pooping, and likely peeing, I'm in a panic that he will get blocked again when I'm away on vacation. My plan is to monitor the motion detection videos daily and call her if I don't see Espy successfully pee.
Hmm, another problem. I just checked the videos (via remote desktop) and the motion detector is definitely reacting to the sun. A sunbeam is making its way across the litter and the camera thinks it's a cat.

I'll have to knock down the sensitivity another notch and maybe find some curtain to block the sunlight. But of course Epsy likes jumping onto the bathroom window sill - argh.
