A Little Color, Big Connection
At ELKRTG, we're not just making doorbells. We want every ring to be a small, colorful moment of connection.
Life is better in color.
Life is Better in Color
A doorbell is supposed to be the first greeting you receive at home. But it’s been nothing more than a monotonous blue indicator light—not really part of the home. We believe it doesn’t have to be that way. ELKRTG decided to add adjustable, multi-colored pulsing lights to the doorbell. You can choose a touch of orange for your morning coffee, a hint of purple for your child’s bedtime, or a soft blue for your hearing-impaired parents.
Built to Withstand Heavy Use
Tested for 80,000 presses. Durable for daily use
Power That Lasts Years
CR2032 battery lasts 3 years (5 presses/day). No frequent changes.
Weatherproof for Every Season
IP55 waterproof, works -4°F to 140°F. Resists rain, snow, sun.
Everything You Need in the Box
Includes adhesive, screws, anchors, screwdriver & sticker.
Is this doorbell truly waterproof? Can it withstand heavy rain in the garden?
Absolutely! The U5 doorbell transmitter meets IP55 waterproof and dustproof standards and has passed submersion testing. It's designed to operate flawlessly in temperatures ranging from -4°F to 140°F (-20°C to 60°C).
Will signal interference occur if neighbors use the same brand of doorbell? Also, is installation complicated?
Absolutely not. Each doorbell set uses a unique frequency code, ensuring zero interference. We've pre-paired the transmitter and receiver at the factory. It's truly plug-and-play—no tedious synchronization steps required right out of the box!
After a power outage, do I need to reselect my favorite doorbell melody and volume?
No worries! It features smart memory technology. It automatically retains your last melody and volume settings even after power loss or when changing the receiver's outlet.
How does the color-changing breathing light work? If I want to turn off the sound, is it useful?
When the doorbell rings, the receiver flashes a soft, color-changing breathing light, and you can select a single color to display. Press the center button to mute the sound or adjust the volume to zero. This meets need when your baby is napping.
Is the doorbell button easy to press?
The buttons have been factory-tested to withstand 80,000 presses. Under normal household use, they have a lifespan of 15 to 20 years or more.
