On Alza, there's a video doorbell for 1,240 CZK that sees in the dark and sends notifications to your phone. Is it worth it?

A Wi-Fi video doorbell with a Full HD camera for twelve hundred crowns. The Tellur Video DoorBell is on Alza for 1,240 CZK with code ALZADNY50. On paper, it looks decent — a 1080p camera with a 130° viewing angle, PIR motion sensor, night vision, two-way communication via the app, and support for both Google Home and Alexa. However, in practice, we don’t have enough data for a full recommendation — the product only has 2 ratings and a 50% recommendation rate on Alza. So, let’s consider this an interesting discount on a product where you should expect a certain degree of uncertainty.

Quick summary:
✅ It might make sense if you’re looking for an inexpensive video doorbell for a basic overview of who’s ringing — and you don’t mind that it’s not a proven bestseller.
⚠️ Consider that it only has 2 reviews on Alza, is powered via outdated micro USB, has no battery (must be permanently connected to a power source), and the Tellur Smart app doesn’t have the best reputation.
💡 For 1,240 CZK, you get a Full HD camera, a PIR detector for 8 meters, night vision for 10 meters, IP54 resistance, and a micro SD card slot up to 128 GB.

What it offers and where the question marks are

The camera records in 1080p with a 130° viewing angle and H.264 compression. The PIR sensor detects motion up to 8 meters away and sends you a notification to your phone — so you know someone is moving near your door even before they ring. Infrared night vision up to 10 meters covers the entrance even in complete darkness. Two-way audio via microphone and speaker allows communication with visitors through the Tellur Smart app. The doorbell supports Google Home and Amazon Alexa, and recordings can be stored on a micro SD card (up to 128 GB) or in the cloud.

IP54 resistance is sufficient for rain and dust — for outdoor mounting under a shelter, it’s fine, but I wouldn’t expose it to direct downpours long-term. The dimensions of 4.5 × 11.4 × 2.6 cm are compact, and installation should not be an issue.

Why we have reservations

Let’s be honest — with a product having two reviews and a 50% recommendation rate, it’s impossible to say with certainty how reliably it will function long-term. The only user review on Alza mentions that the doorbell does not have a battery and is powered via micro USB — in 2026, this is an outdated connector that is gradually disappearing everywhere. Therefore, you must ensure permanent cable power, which complicates installation. The Tellur Smart app works, but it’s not among the highest-rated.

For 1,240 CZK, it could be a reasonable entry into the world of smart video doorbells if you don’t want to invest four to five thousand in established brands. Just have realistic expectations — it’s a budget solution with all the limitations that come with it.

Do you have a smart video doorbell at home, or is a classic one enough for you?
