OhmKat Wireless Universal Video Doorbell Chime (Patent Pending) - for Use with Nest, Ring, August, Skybell, Simplisafe, Alula Compatible OhmKat Video Doorbell Power Supplies

First class, highly recommended, excellent in every way!

The product is really easy to set up, with or without an Ohmkat power supply. The documentation is brief but the circuit diagram and voltage limits are really all you need. There are good videos on YouTube showing step by step instructions if needed.The good news is that although the product picture on Amazon UK is an older model, the supplier shipped the current Ohmkat version.The only slight negative is that it comes with a US plug, so you would need a fairly bulky US to UK adaptor.

Item supplied was for US plug socket, not UK so have had to return. Will be ordering directly from Ohmkat in the US as despite taxes and shipping costs, overall costs are similar and it they have a UK specific model.
