OhmKat, Inc.

Received an earlier version of ringer. Had issues with phantom rings. Friendly courteous and accessible customer services promptly offered debug options, and when those did not work, immediately offered a replacement that is working to perfection. Will recommend immensely.

We bought the original chime & then added one on the patio (under roof) and happy to know we won't miss hearing the doorbell outside too.

OhmKat Video Doorbell Power Supply - Compatible with Nest Hello

Just what I needed. Thanks for your help!

Got all the parts in, had it working in less than 30min, If you dont have a door bell you need to get a ring door bell and use OhmKat system to make it work, I bought 2 ringers put 1 in living room and one in master bedroom they are wireless and work great.

Got the device very quickly and instructions were very clear with excellent photos. Didn't have to try and translate broken Chinese to figure out what to do. Terrific company!

Simple installation and it works with my ADC VDB770!!! Very happy with this purchase!

Glad to find this as an option after getting a costly quote for installing full electrical required for doorbell camera. Item shipped quickly and was very easy to setup and install. Would definitely recommend to others considering a costly wired doorbell installation.

VERY easy to install and worked without a hitch. Sounds like a real "old-fashioned" ding-dong doorbell, which I like. Goes well with Simpli-safe video doorbell, as advertised. Fantastic customer service. I ordered an additional chime, not knowing if I'd need it, but after installing it I found I could hear it well anywhere in the house. I wrote to OhmKat customer service (on a Sunday night) and got an email back immediately with a mailing label (prepaid) to return the unneeded chime. They credited me as soon as the postman picked it up. I was blown away with their responsiveness, which is very unusual these days!

Worked perfectly! We were able to set up our simply safe doorbell camera with no problems and without having to rewire anything

I needed to install a ring and a google nest doorbell in two separate locations. Neither had working existing doorbells. I didn’t want to deal with soldering in appropriate resistors downstream of the transformer (which were no longer working) so I used ohmkat power supplies. Simple effective solution. Both video doorbells have been working flawlessly. Thanks gentlemen.

Very good product. Awesome customer service I would recommend anybody that has a doorbell to buy this

Excellent

I installed a Lorex wireless video doorbell as a stand alone product. It worked great except it had to ring my phone when someone pushed the button. I looked everywhere to find a way to get it to ring a chime but that was impossible without a wired doorbell chime connection. OhmCat solved the problem. It was a simple installation.

Initially there was a technical issue with Lorex ringing the bell when a video alert was sent but OhmCat worked with me to make an enhancement to their product and shipped me an updated product at no cost. I couldn't be happier with the support or the product. It's wonderful to find a company that stands behind their products.
