I have been using an ASTEK Mole
camera for a year. I use it wired, but it is also wireless. Probably the best feature is the proxy
service Yoics.com that you can use to connect to the
camera. I didn't think I would like it, but it works well.
So, the boat
radio connects to the
Internet, while the internal AP can support this camera (I use it wired though for PoE), and it doesn't matter which type of data connection the boat has. The camera is always accessed through the proxy
service. I use a combination of cellular data and
wifi to connect the boat network to shore.
I set the view on the camera, then enable a motion detection window, and the camera emails a snapshot and onboard SD card records video when something passes through that zone. It's PTZ and has IR illumination.
Not that it matters, but I found it at Costco. When underway, I just pull the
plug. It is not supported through my NavNet3D like the AXIS cameras, but those are not "cloud" enabled, that I know of, and do cost more. Although, I am only using the camera for
security, and not watching a
deck or the
engine room.
I guess that with some extra configuration, you may be able to connect it directly, as a client, to a free
WiFi hotspot in the harbor. I would really consider how open it might be to curious hacks, and take measures.
