Thanks for learning about OhmKat. We created OhmKat to help solve the frustrating problems we encounter in technology today. Sometimes we just can’t get it to work!

With that thought in mind, we created our first family of products – the OhmKat Video Doorbell Power Supplies. We had a problem – we didn’t have electrical doorbells on our homes but wanted the security of having a video doorbell. Frustrated that we couldn’t just plug it in, we designed a novel way to do just that. With our Video Doorbell Power Supplies, you can now attach our unit right to the video doorbell and then plug it in. Super simple.


Our power supplies work with: Nest Hello, RING Video Doorbells, Simplisafe, Alula, Skybell, August, Arlo, Zmodo, and others.


Video doorbell installation without an existing doorbell has never been easier
