With 2 push buttons offering 52 melodies and 5 volume levels up to 115 dB, it provides customizable alerts for front and back doors. Easy to install with included adhesives and screws, it runs on long-lasting CR2032 batteries with ultra-low power consumption, making it perfect for modern homes seeking seamless connectivity and style. ## Description Product Description Mini but powerful After carefully analyzing user experience, we have redesigned this receiver to make it even more compact, measuring just 7 cm by 7.8 cm, so it doesn't block other outlets in power strips. However, this was done without compromising performance. Expandable with multiple receivers Expand your existing AVANTEK doorbell system in minutes with up to two transmitters and multiple receivers for your specific environment using the simple pairing method. Customizable melodies for individual transmitters Personalize each transmitter with independent melodies and never guess which door has been rung! Always welcome your visitors in a timely manner. Long Range The doorbell can operate up to a distance of 300 meters (depending on the environment it is in). Rest assured that you will no longer miss any important visitors or urgent deliveries thanks to this doorbell. Robust and Waterproof Transmitter Pleasant Melodies The wide selection of 52 melodies allows you to choose the ones you love. Moreover, the built-in 29mm diameter stereo speaker emits a clear and well-balanced sound that can reach 115 dB, ideal for assisting even the elderly when someone rings their doorbell. Additionally, the lowest volume level (0 dB) won't disturb a sleeping baby, and with the LED light alert, you will be notified of a visitor without being disturbed. Long Lifespan The integrated CR2032 lithium battery with a capacity of 230mAh has a long lifespan of 3 years, sparing you the worry of frequent purchases and replacements. Innovative Memory Function One of the great advantages of the AVANTEK doorbell is its memory function. Every time you use it after a power outage, it will remember your last melody selection and its associated sound level. This not only makes it extremely convenient but also very user-friendly. Easy Installation Choose between two simple mounting methods: you can either attach your doorbell to the wall using the adhesive sticker or use the provided screws. All necessary accessories are included in the packaging for a convenient installation. Review: Very simple setup - Excellent product that works exactly as intended. We live in a townhouse so the family room is upstairs. Our doorbell worked occasionally and most deliveries came to our back door which didn't have a bell. This meant we missed most parcels. Enter this AVANTEK setup. Two bells with adhesive pads and one receiver. Receiver is loud and small, set to a normal bell as default and the pairing process took seconds. I got what I wanted and I am delighted. Colour is also pleasant on my grey UPVC doors. Can't comment on battery life as it's just been installed, but it really was so easy to setup and use. Review: Very easy to fit - Works perfectly, straight out of the box. Had mine for a couple of months now. Here's my thoughts.... Pro's: 1. Easy to fit (very easy. double sided tape is great on upvc doors, screws if using on brickwork) 2. Easy to setup. There are 2 bell pushes which can have different sounds, so you know back or front door etc. 3. Very weatherproof - a weakness of many other types. Con's 1. Nowhere near the claimed 300m range. Works fine in the house but a test showed it ran out of steam at just under 100m. 2. Ours stopped working. When I prised the bell push off the base, I noticed the little battery had slipped down inside it's holder, breaking contact. Pushed back up and added a tiny bit of blu-tack fixed this. All in all, it's the best wireless doorbell i've fitted in years and I'm an Electrician who's fitted dozens. ## Features - 【HIGH PERFORMANCE 】Our AVANTEK doorbell is approved by CE, FCC and RoHS.

How do you give the two transmitters different rings?** A: After searching all over I found out how to do this, to make it easier get someone to help you if you've got two transmitters (front and backdoor doorbell buttons let's say) already attached to the walls. 1st. If you've got multiple receivers make sure you can hear them clearly, I plugged mine all in in the same room I was in. 2nd. Ask the other person to press the first door doorbell every two seconds whilst you remain in the room with the receivers so they all chime at the same time, use the chime select button on the first receiver to pick the chime straight after the other person presses the doorbell, do this until you get to the chime you want. At this point one receiver will be chiming the chime you want and the others won't, repeat this process on each receiver until all of them are chiming the same chime. All the receivers are now programmed to chime that chime for that doorbell. 3rd. Ask the other person to go to the second doorbell button and repeat the whole of step 2 again but this time select the different chime you want to use for that doorbell. 4th. Now you test each doorbell, each one should chime a different chime from the same receivers. 5th. Be happy you can tell which doorbell is pressed from the chime that chimes! **Q: We live in a country area with quite frequent power cuts and blips. Do the units have to be re-paired every time there is a power cut or blip?** A: No, dont have to be re-paired **Q: the doorbell rings when landline rings how can I stop this happening** A: I'm taking it your landline is cordless phone so I'm guessing it must be set on a frequently near to the doorbell frequency hence the interference I don't think there is a way to get round it it as pressing the doorbell is sending a signal frequency to the receiver your phone must be doing the same do you have have two hand units have you tried unplugging the single one without the base unit the one just with the charger as was wondering if the transmitter from the base unit to the other phone to meet that one ring is crossing the doorbell line hope you get it sorted **Q: Will it work with Blink video doorbell ?** A: Dear Customer, No, it can't work with Blink video doorbell, it just work with AVANTEK Doorbell. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very simple setup *by A***R on 15 January 2025* Excellent product that works exactly as intended.

Purchased the one with 1 chime and 2 bells. Very easy to set up,, and was able to back and front doors different sounds. The chime doesn't take up too much space. Only negativity is I found some sounds are a bit 'tinny'. There are 52 different sounds to choose from, but once you set 1 bell, you automatically go back to the beginning of the sounds before you can set the 2nd one. Be warned, when you plug in the chime, the first sound you will hear is a very loud 'cock-a-dooodle-do'. The bell push can be screwed to the door frame/wall or attached with sticky pads which are supplied. ## Frequently Bought Together - AVANTEK Wireless Doorbells, 1000 ft Range IP55 Waterproof Cordless Door Chime Kit with 2 Push Buttons, 52 Melodies, 5 Volume Levels, LED Flash, CB-21, Suitable for Front Back Doors Entrance Ways - MASTER LOCK Key Safe Wall Mounted, Medium 85 x 119 x 36 mm, Outdoor, Mounting Kit, for Home Office Industries Vehicles, Black & Silver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/97370942-avantek-wireless-doorbells-1000-ft-range-ip55-waterproof-cordless-door](https://www.desertcart.tn/products/97370942-avantek-wireless-doorbells-1000-ft-range-ip55-waterproof-cordless-door) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-05*
