Security Camera with FTP Upload

I've got an old webcam I've been using as a security camera for years. Its outside but under cover and when it detects motion it capture and writes 720p video files to an FTP service I've got in the cloud. It's getting old and flaky so its time to replace. The FTP feature has worked well enough, I tend to keep a year of data before purging, I've got heaps of space, and the FTP service is free for me. Any reccomendations on a new cheapish device? Needs wifi, night vision, higher res would be nice, motion capture and either saves long term to FTP or some sort of cloud service. I don't want to pay any ongoing subscriptions.
