OhmKat, Inc.

After renovating my home, and all was sealed up and done, the doorbell was disconnected from power and chime. OhmKat’s products made the repair easy and I am so happy! Highly recommend

I ordered a door bell kit for my SimpliSafe front and rear video doorbell. I forgot to order a second transmitter. They realized this and packaged an extra one free of charge. What company cores that these days? Fantastic quality product and amazing service. Thank you

I had OnTech install my SimpliSafe system and they charged me $50 for a Wasserstein adapter that worked for 2 weeks and then fried the doorbell camera battery. Turns out it was the wrong voltage. Ordered this Ohmkat adapter, installed it with a new doorbell camera and VIOALA... It woked!!! AMAZING! Now I'm waiting for OnTech to refund me my money for their incorrect adapter... But I'm definitely not holding my breath.

I bought this for my simplisafe system. I don’t have any existing wiring to where I wanted the doorbell so when I found this, I knew it would work.
I needed extra wire, so I ordered it, and then reached out to customer service to discuss and we ended up changing my order and it ended up perfect. 10/10 if you don’t have existing wiring to tap in to.

Because we no longer have an analog doorbell, I kept blowing doorbell transformers powering my Simplisafe Video Doorbell camera. Sometimes over a period of years, sometimes immediately. After reading about OhmKat in one of the Simplisafe forums, I ordered their power supply and installed it in my garage mid-August. Arizona's summers are brutal and the uninsulated garage gets to 110+ F regularly. This year was no exception. The supply has now been in place for one month and it has operated flawlessly. Installation was straightforward and their Customer Support is responsive and helpful. I am delighted by this product.

Works great and super easy to install. We have the POWER!

Working perfect.

Performed as marketed. Easy install.

Works well with Simply Safe doorbell camera. The installation is straightforward.

Easy installation and the chime is loud and effective.

I decided to install a Simplisafe Video Doorbell on the back door of my house in Florida. I already had an identical camera on my front door that was connected to the same kind of power supply. It works great, so I wanted to get another to run the new camera on my back door. Amazon no longer carries them, so I bought one here. It works great with the Simplisafe video doorbell camera. It was also shipped fast, which I appreciate.

Plug and play. Worked as promised.

Works fine. Compltely compatible with the simplisafe doorbell.

Ordered OhmKat receivers, they arrived in a timely manner, and very well packaged. Extremely easy to do the full installation, since attached schematic / drawings and instructions were very well written. Took just about 5 minutes to do a full installation. Highly recommend OhmKat, Inc.

These Ohmkat chimes work great. The staff even set them up to be paired before we received them. We can place them where ever we want them in our home. The price was almost too good. Thank you for the wonderful product and buying experience. :):)
