Tom - Here is a thought... That Panasonic was cutting edge in the Analogue camera world. Many bells and whistles that no other camera had. And even though it aged well, these days its inability to connect to secure rich email servers etc may have done it in. But you still can find them for sale and used.
It's class of cameras these days fall into what is called often a "Nanny" cam or "baby monitor". As others have said most of the features you seek are embodied into outdoor class CCTV cameras. The others are the type that can direct support iOS and Android phones with native apps which I suspect you have already cruised through.
Another approach is not to get an all in one "toaster" appliance but get a decent camera and a price you like and then farm out the ftp to software. You can easily get your a, b, and d off the shelf. Then for c - Depending on what your station is running for OS, many have optional FTP servers, or just as easy just download industry standard available low cost or free and more importantly in my book, updated regularly to close security holes software such as FileZilla. Most cameras these days can be viewed or "monitored" on your LAN with just a standard web browser due to their built in webservers. Many now support https/ssl connections because they are being marketed as "security" cameras.
D-Link makes a few cameras that fall into your price range and below. Foscam, Wyze also make some real good cameras. Wyze has a 50 buck outdoor that has great quality views and just because it is marketed as outdoors, you can run it indoors.
Hopefully you will find a solution you feel comfortable with, and can be as stable and long-lifed as your Panasonic was.
