AVANTEK D-3W Wireless Doorbell

When it comes to wireless doorbells, all you need to do is a quick search online about AVANTEK to know that it is one of the best brands out there.

Founded by a small group of young professionals not too long ago, AVANTEK aims to provide products that lead to easier and smarter living.

They promise high-quality products at affordable prices with 100% customer satisfaction.

Besides the wireless doorbell, they also sell white noise sound machines, laptop cooling pads, binoculars, hair clippers, and a lot more.

Nevertheless, their wireless doorbells are their best selling products.

They have a whole range of wireless doorbells, and today, we’ll be reviewing the AVANTEK D-3W Wireless Doorbell System.


  • Customizable Sounds and Volume

The AVANTEK D-3W Wireless Doorbell has a 40 mm stereo speaker system that produces a loud and clear sound that can reach every corner of your house.

On the other hand, if you don’t want your doorbell to be that loud, you can easily adjust its volume.

This system comes with five-volume settings. The lowest setting produces 0 dB of sound, which means that you can mute your doorbell.

The highest setting produces a maximum volume of 115 dB, which can pretty much be heard over a rock concert.

Aside from that, there are 52 tunes to choose from.

Not only will it be fun to browse through all of them, but this means that you can have a different tune every week of the year.

  • Ease of Operation

This wireless doorbell system has an operating distance of more than 1,300 feet, which is twice the range of ordinary doorbells.

Moreover, for people who don’t need that much coverage, there is another pack available that contains just one receiver and transmitter.

Similarly, if you need even more coverage, you can buy another box, and both new and old systems will pair easily.

However, the metal around the transmitter can affect the signal and operating distance, so you’ll need to choose where to place it carefully.

Besides that, the receiver also has an LED light.

Consequently, even if the system is on mute, you can be alerted by the LED light.

More importantly, if there’s any hearing-impaired person in your household, they can also be informed of a visitor at their door.

  • Transmitter

The 3.3 x 1.6-inch transmitter contains a 230mAh CR2032 lithium battery.

It is designed to have ultra-low power consumption so that the transmitter can last up to three years without a battery change.

Additionally, you also don’t have to worry about the transmitter getting damaged by rains.

It comes with an IP55 rating, which means that it is dustproof and waterproof.

It’s safe to use even in heavy rains. Furthermore, it can withstand extreme weather conditions, from -4 degrees Fahrenheit to 140 degrees Fahrenheit.

However, unlike the receiver, the transmitter does not have an LED light or indicator.

Therefore, it can be hard to spot at night if it’s too dark.

  • Ease of Use

The AVANTEK D-3W is easy to use and even easier to install.

Along with the transmitter and receivers, the package includes adhesive tape, a screwdriver, two screws, two anchors, and one user manual.

You can either set the doorbell up using the adhesive tape or the screws for more security.

You can also refer to the user manual to learn how to pair the devices quickly.

Any additional receivers can also be paired within seconds.

Moreover, it has anti-interference features that ensure you only get alerts from your paired devices and not any other nearby devices.

The system has a very convenient memory function, as well.

In case of a power outage, the wireless doorbell system will save and resume the settings you had set before the power went out.

  • Warranty

AVANTEK offers a lifetime warranty on its D-3W Wireless Doorbell System.

In addition to that, it also comes with a 45-day money-back guarantee in case of any manufacturing problem.


  • Easy and quick installation
  • Can be used as a pager too
  • Lots of tunes to choose from
  • Long range coverage
  • Long battery life
  • Handy for the hearing-impaired
  • Waterproof and dustproof
  • Lifetime warranty
  • Approved by FCC, CE, and RoHS


  • The transmitter is hard to spot in the dark
  • Metal can shorten transmission range

Summary of the Features

Available in both black and white, the AVANTEK D-3W Wireless Doorbell will be a fantastic addition to your home.

The easy installation means that you can quickly set it up yourself without having to call or wait for someone else.

So, as far as wireless doorbells go, this one has everything you need.

The two, long-range, 3.5 x 3.5-inch receivers coupled with the impressive sound system make it perfect for people living in large or multiple-story houses.

Alternatively, for smaller homes, it can also be bought with just one receiver.

Comparison with a Similar Doorbell

If you’ve still got some doubts, the best way to convince you would be to show how the AVANTEK doorbell compares with a similarly impressive product.

Accordingly, we’ll compare it with the SadoTech Model CXR Wireless Doorbell System.

Similar to the AVANTEK D-3W System, the SadoTech also comes with one transmitter and two receivers with LED lights.

It has 52 tunes, can support additional receivers, and has an adhesive tape.

The transmitter is waterproof as well.

Moreover, it can be used as more than just a doorbell like the AVANTEK.

However, SadoTech has a smaller operating distance.

It can only cover up to 1,000 feet, as compared to the 1,300 feet range of the AVANTEK D-3W. Furthermore, it only has four volume settings, from 25 dB to 110 dB.

The SadoTech doorbell can support more than just additional receivers.

You can add other devices, such as mini window sensors, door sensors, and motion sensors.

They have to be bought separately, though. The SadoTech doorbell is available in more colours.


Ultimately, the choice all comes down to your own need and preference.

If you ask us, even though it’s a close call, the AVANTEK D-3W Wireless Doorbell System is the winner.

It might not have more colours, but it has tons of other useful features that make it a more effective and powerful system against the SadoTech.

Overall, AVANTEK offers more value at a better price.
