Will this camera work?
Lorex 8MP 4K IP Bullet Security Camera LNB8921BW, 250ft IR Night Vision
Do I need any special software?
Lorex makes great cameras. I have an 8 channel NVR with 6 cameras hooked up. I use two of them for my weather website. But it's not a trivial setup. I'm a software developer, so I can "create" stuff where there is a void.
Basically I have an FTP server app running on my LAN that catches the images from my NVR (although I believe the IP cameras themselves can be configured to upload to an FTP server without an NVR). The upload rate is configurable but it's pretty fast, I think the slowest you can go is every 10 seconds. Could probably find a freeware FTP server to run locally to do this.
Then every few minutes it pushes the pictures to my website. You could probably use a task running every few minutes and use a command line command to push them to your webserver. It also reduces the size to WUs standard and pushes it to their FTP server. Not sure how you would do that with available software although I'm sure it could be done.
WU is abandoning their webcam platform. I'm pretty sure that the "make us go look at your website" feature no longer works, and their FTP server is intermittent.
But basically the procedure for a Lorex IP cam is this:
CAM->Local FTP Server->Resize to <150K->FTP to WU
