"Else just take a simple cheap webcam and do it yourself. A webcam, a rPi and a bit of coding ought to get you what you need easily."
This is the exact question I'm asking.... a good quality, (cheap if possible), webcam that can quickly be setup for this task of sending images to a server for a web-page to display. So far it doesn't look to exist.

Making it easy for the common user to send something to dropbox is fine, I just agree with Mobydisk that there should be some support for more advanced standards, if a user decides to tread there (WebDAV, SFTP, etc...). And as for FTP, it seems the cameras that support it (e.g., Foscam, Hikvision, etc...) don't support SFTP or FTP-S, the all only support vanilla, insecure, FTP....but that's a different issue.

I went into this thinking it could all be setup in no more than a few hours one afternoon; many of these solutions will take many days. (e.g., rPi is an interesting avenue, and may be something I'll jump into, as I've wanted an excuse to play with one, but it won't be "quick")

The ice-cream shop is small, "mom and pop" shop; the owner is the manager.
Your inference is off, they are not crazy and most definitely not lazy; in fact the opposite which is why they are pursuing this endeavor.

This is a good idea; they actually do this already. They want to take it to the next level... hence a Slashdot question. 8)

Would love to know if anyone has follow up on this.

That is a good question...
It doesn't have to be trigger by motion; that is just a likely scenario when the menu board is updated. It could also upload a new photo every so many minutes/hours ... the trick would be to pick an interval that is frequent enough to be up-to-date but not so frequent that they much through their allocated bandwidth for the month from the frequent uploads.

Thank you; had not heard of this brand before.
The TV-IP562WI may do the trick.

An interesting approach but it has some issues for this situation:
1) The potential web camera is on a LAN with an IP that isn't web visible
2) The idea is not to have to dedicate any other computers to get the image up
3) The shop does not have a static IP address

All of these are addressable, but if the camera can push the image out, rather than someone reach in to pull it from the camera, it seems to be a much easier task.
(Or it would be if the Hikvision FTP was working as claimed in the manual.)

The end goal is to have a web-page that displays the image; FTP is just a way of getting the image to the page.
The Foscam they tried did have FTP build in but image quality wasn't up to snuff.

Thank you for mentioning the Zoneminder wiki/forums; that seems to be a good source of information from people having utilized the equipment they talk about.

Know Nutter: Thanks for the link.
Anon: Thanks for the notice on the resolution... there may be a DLink solution; the one KN mentioned is a bit low (640x480) but I see there are some at 720p which may do the trick if they go in this direction.

Thank you, this is definitely an option.

Thank you. May not work as the existing camera mounts are from the ceiling; not easily accessible... still worth checking out; perhaps there is a hack.

This is fantastic; hadn't come across Mobotix or Axis.
Will check them out. Thank you.

Immerman: If you know of an App, please pass on the word. The key is that it needs to be triggered if there is motion (when the board is updated).

koan: I thought of a iPhone or Android that could do the trick but would need to find a piece of software that can activate with motion, and FTP the image up to a site. Webcams are essentially build for this, with both video and images. The problem is, the older ones have horrible resolution. The newer webcams look great (720p, 1080p, good sensors, etc...) but are all working on a model where you have to pay to access the feed from their "private cloud". So I hear you say "webcam" is the problem... great I agree... but what do you offer as a solution?
