Marvin,

With our elite systems you can do basically all of the things you asked to except for recording directly to a smartphone (though of course you can always access your camera system from a smartphone.)  There are a few caveats though to all of it and if you're looking for weeks of footage I would likely recommend a small 4 channel NVR/DVR for ease of use/access.  We have plenty of units that can record to SD, but most of them cap out at around 128GB.  If you're clever about scheduling and it's a low traffic setting you might get a few weeks but if it is recording pretty consistently then even on motion a 128GB card will likely only give you a few days of footage.  Our PC software has a remote server you can set up, but all backed up footage would have to be viewed directly from that computer, there is no easy way to access that footage from your smartphone.  This is also the case if you backup directly to an ftp server, which our units are also capable of doing.  The video file segments that will backup to ftp would need to be viewed with the pc media player made for your system.  If you have an elite recorder that your camera is paired with (or record straight to sd card), then you can review your footage on any device seamlessly through the same app you use to live view your camera and the whole process is simply more organic and straight forward.

For a single room, single camera, simple indoor setup our https://www.securitycameraking.....ty-camera/ is pretty popular.  Just make sure you purchase the optional power supply and SD card for the camera and all you have to do is plug it into a wall outlet, connect it to your wifi and set up the EVP smartphone app and you're off to the races.  The 128GB card can hold about 72 hrs of footage.  

If you don't mind some extra cable management, then a 4 Channel recorder with a 1TB hard drive will give you possibly months of recording and a wide range of pricing options.  The catch is you generally want the camera to run directly to the recorder and the recorder has to be hardwired into your router for internet connectivity.  Even newer platforms that don't require you to hardwire the camera to the recorder would at least need to be hardwired directly into your router for internet connectivity.  You CAN hardware the https://www.securitycameraking.....ports-poe/ NVR into your local network and pair it with one of our WiFi cameras as well to reduce the need for as many cables.

I hope this gives you some places to start from.  Please let us know if you have any questions about any of the products I've mentioned, or if perhaps there are other products you are interested in if you don't mind running some cable.
