Hello.
I think we need to better understand your goal here. Are you wanting the camera to move between pictures, so it shows a different view every 10 minutes? I ask because PTZ (pan/tilt/zoom) capability adds a lot to the cost. I do not know if Foscam supports a PTZ schedule that would meet your goal, either, since I do not use Foscam cameras. It might require 3rd party software to pull that off. Maybe even custom software written just for you. Maybe @
Don can tell you more about the Foscam's PTZ scheduling abilities.
About the idea of using WiFi, I must recommend against this. If your tower has any 2.4 GHz radios on it already, the camera would be a new source of interference. Even if there is no other 2.4 GHz activity on the tower, there is little reason to use WiFi for this. You already have to send power up to the camera, so you might as well send up a shielded cat6 cable as well for data. Or better yet, choose a camera that supports PoE (power over ethernet) and then you only have to run the cat6 cable. Again, I recommend shielded cat6 cable, since the shielding may reduce the chance of causing problems for any radio equipment on the tower.
So anyway what I recommend is that you look at Hikvision DS-2CD2032-I bullet cameras. They do not pan, tilt, or zoom, but they are higher resolution, they are physically very small, and you can probably find them for less than half the price of the Foscam you mentioned. The standard model has a 4mm lens which gives a fairly wide field of view, though you can choose one with a 6mm lens with a bit narrower view, or 12mm for a much narrower view. For landscape views you probably want the widest (4mm). I have used several of these for scenery/weather cams, and they are great.
Anyway at their price, you could afford to buy more than one, then have two or more great looking cameras for the web site.
If you get the Hikvision camera(s), they support PoE so you just have to run one network cable for each camera, and it will carry both the power and data. Ideally the cable should be shielded and outdoor rated (UV resistant) cat6, though
cat5e would work fine also. You run the cable from the camera all the way to the inside of the building, where you plug it into a PoE switch ($40 USD and higher) or PoE injector (about $20 USD, but only powers one camera).
As for having the pictures appear on the town website, this can be complicated but there are a number of methods you can try.
1. Hikvision cameras have built-in FTP capability, but you can't specify the file name and it always puts a timestamp in the file name, so it never replaces old images. For this to be usable you would need some server-side code that finds the latest image and deletes old images.
2. Foscam also has FTP capability, though I do not know its limits. Again, Don can probably tell you more.
3. Don's software he linked should be able to do what you need efficiently, and for a small fee he will help you set it up.
