Smart doorbell under 1,500 CZK: This one has a 2K camera with night vision and an indoor chime

Smart video doorbells with 2K resolution cameras usually range from 2,500–4,000 CZK. However, the Imou Doorbell 2S Kit can now be purchased with code ALZADNY20 for 1,431 CZK instead of the usual 1,899 CZK. The package includes not only the doorbell itself but also an indoor chime with a Wi-Fi extender function, so you don’t need to buy anything else.

Quick summary:
✅ Makes sense if you want to see who’s ringing your doorbell when you’re not home — and you don’t want to spend an hour installing cables.
⚠️ Consider if you need continuous, uninterrupted recording — battery-powered doorbells only record upon motion detection.
💡 For 1,431 CZK, you get a complete set with both the doorbell and an indoor chime. Separate video doorbells of comparable quality cost a thousand more.

Why this doorbell is interesting

The main advantage of the Imou Doorbell 2S Kit is its complete package for the price of a standalone doorbell. Included with the video doorbell is an indoor plug-in chime, which also functions as a Wi-Fi signal extender. For households where the Wi-Fi signal at the entrance is weaker, this is a crucial feature — without it, video doorbells often suffer from latency or outages.

The second advantage is wireless power from a 5,000 mAh battery. The manufacturer states a battery life of up to 120 days on a single charge (with 20 fifteen-second events per day). Charging is done via a USB-C port, so a standard cable is sufficient. Installation involves screwing on the bracket and attaching the doorbell — no drilling into the wall for cables, no electrician needed.

Camera and image quality

The camera offers a resolution of 2048 × 1536 pixels (2K QHD) with a 4:3 aspect ratio. This is more practical for video doorbells than widescreen 16:9 — you’ll see the entire figure of the visitor from head to toe, including any package at their feet. A 125° field of view covers a wide area in front of the entrance, and if you need more, the lens can be remotely rotated 30° horizontally via the Imou Life app.

At night, IR illumination with a range of 5 meters is activated, providing a clear black-and-white image even in complete darkness. This is sufficient for a typical family house or apartment with a hallway. The H.265 compression codec means that recordings take up less space — you can fit significantly more hours of footage on an SD card than with older doorbells using the H.264 codec.

AI detection and smart features

The doorbell uses not only a standard PIR motion sensor but also AI human shape recognition. In practice, this means that notifications are sent only when a person is actually standing in front of the door — not when a dog or car passes by. If you still have issues with false alarms, you can define a specific detection zone within the camera’s view in the app to address, for example, a street that falls within the field of view.

Two-way voice communication is also available — you can speak with visitors via the app on your phone, wherever you are. This is useful for couriers (“leave the package at the door”) or when you want to create the impression that you are home, even when you’re not. According to the manufacturer, phone notifications arrive within 0.3 seconds of detection.

Recording storage and app

Recordings can be stored in two ways. Either locally on a microSD card with a capacity of up to 512 GB (card needs to be purchased separately), or on the Imou Protect cloud. Local storage has the advantage that you don’t pay any monthly fees and your data remains with you. Cloud storage, on the other hand, offers a backup in case someone removes the doorbell.

Control is done via the Imou Life app for both Android and iOS. The app also supports device sharing among multiple household members — so everyone can see who is ringing and potentially respond to the visitor.

What users say

On Alza, the Imou Doorbell 2S Kit currently has only 2 ratings with an average of 5.0 out of 5, but both customers recommend the product. Over 20 units have been sold. The sample size is still small, so it’s worth waiting to see how the model performs in the long run.

From general experience with Imou brand doorbells, it holds that the Imou Life app is reliable and clear, but the Czech language in it may be incomplete in places. Critical voices regarding battery-powered video doorbells generally point to the fact that the battery needs to be recharged more frequently in winter — cold significantly shortens battery life. The stated 120 days apply under ideal conditions.

When it doesn’t make sense

If you want continuous 24/7 recording, a battery-powered video doorbell is not for you — it only records upon motion detection. In such a case, look for a wired model powered by existing doorbell wires, or an outdoor IP camera directly.

Also, if you require integration with premium ecosystems like Apple HomeKit or advanced features such as a dual lens (doorbell + view of a package at the door), opt instead for the Eufy Video Doorbell E340 for 4,990 CZK or the TP-Link Tapo D235 for 3,619 CZK. However, you won’t get comparable features at the Imou price point.

Verdict: who it’s worth it for

For 1,431 CZK, you get a complete video doorbell kit with an indoor chime and a 2K camera. For most households that simply want to see who is ringing their doorbell and receive notifications on their phone, this is a very reasonable choice. Easy installation without wiring, AI human detection, and a 120-day battery life make this doorbell a practical solution for apartments and family homes.

If this particular model didn’t appeal to you, but you’re looking for a smart doorbell or other security elements on sale, you can also browse the current Alza Days, where other discounted video doorbells and IP cameras regularly appear.
