Not quite what you're asking for, but here's what I'd attempt:

  * Take an RPi with video codec licenses enabled on it, and put in a
    rather large SD card.
  * Install your distribution of choice, and configure a command-line
    Web cam application to record any attached Web cam.  This would use
    the V4L2 API provided by the kernel, and should work with any
    half-way decent USB camera.  I tend to prefer Logitechs.
  * Come up with some sort of enclosure that will protect the whole kit
    from weather.
  * Bonus points if you can use the GPIOs to implement a battery
    management for the Pi's power supply and maybe use wind/sun on a
    small scale to keep the battery charged.  The battery needs to be
    able to supply up to 10-12W of power at peak.  Otherwise, you'll
    need to figure out a means of getting power to the unit.

At that point, you can implement the rest of what you're asking for 
pretty trivially.
