I have 7 RLC-410 or 410s cameras.
If the only option is to replace them to get support, I would rather go for a different supplier....
As if they drop support after only a couple of years, where will that leave us with the new models.
If they are dropping support, why not make it open source.

To what end..
They can only say that this hardware is no longer supported.
