OhmKat, Inc.

Easy to use ,and superb customer service.

Great to have this option for hardwired doorbell cams. Works like a charm!

I was sent the wrong item twice but finally after receiving the correct item, per the description, it worked like a charm. The return process for the incorrect items was very easy. Thank you!

Great customer service. The only SimpliSafe power supply for those without an existing doorbell.

Works great with simply safe doorbell. Easy to setup. And great price.

Power supply works well

I Purchased the Ohmkat power supply and additional door chimes. The Ohmkat solution with Simplisafe Doorbell Camera works perfect, I highly suggest it.

The power supply works as described. I was apprehensive about the doorbell installation because we don’t have an existing doorbell, but I was so eager to get my SimpliSafe equipment installed after pulling the plug on the previous provider after terrible service. I really didn’t want to pay an electrician to run power for a doorbell chime to wire this doorbell to. That technology is practically obsolete as it is. This power supply was the perfect solution. OhmKat also has several helpful videos on YouTube. All I needed was a longer drill bit to get the wire into the house from outside and some outdoor sealant to protect that hole from water — that’s the part that nobody tells you! The power supply has been installed for over a week now and everything is working great.

Once hooked up, worked great, better than the hardwired to the mechanical chime with all the buzzing, etc. So thank you.

OhmKat Video Doorbell Power Supply - Compatible with SimpliSafe Pro Smart Wi-Fi Video Doorbell

Wireless Universal Video Doorbell Chime (Patented)

Installing the Ohmkat power supply and chime on my SimpliSafe video doorbell couldn’t be easier. Literally a plug and play system. Kudos!

After burning a few traditional transformers, OhmKat finally gave me the proof that my old SimpliSafe camera was the problem. This helped me get a new camera shipped by SimpliSafe, and now everything is working great (with OhmKat).

Works great. I had one in my previous home for years. I never had had an issues, so why mess with anything else.

Very simple to install. And very compatible with SimpliSafe. Initially, I bought the Transmitter plus two doorbells. Then I added two more doorbells. So four doorbells - kitchen, den, bedroom & back patio - no range/distance problem. Happy customer.
