this is a very special requirement, maybe someone did a similar installation and can help me:
I look for a digital picture frame with following parameters:
Size should be at least 14 inches. It would be favourable, if the frame would forsee any wall assembly. There must be buttons available on front side to start/stop the slideshow and to skip certain pictures/videos.
I need to install about 30 of the frames and need an easy synchronization option. WIFI is not an option, as it is not allowed in the area where the frames will be installed, so I was searching for frames with a LAN RJ45 port. But as we are living in the future it seems no manufacturer exips his devices with LAN anymore.
My second idea was to connect the digital picture frames with an USB cable to a pc. SO I would connect all 30 devices over an USB hub to one PC. But the test frame from AGFA switched to data transfer mode as soon as on USB cable is attached. This would mean that I have to connect/disconnect all 30 devices when doing an synchorinzation.
Putting data on the digital picture frame with an USB stick seems to be now the only solution, but then I have to touch every of the 30 frames once, this is a lot of work.
Does anybody have a better solution. Does anybody know about an device with an LAN port. Does anybody own a device which continues the slide show while a PC is connected to upload data.
Is there maybe another option which I missed to consider?
