Video Doorbell: Guide to Choice and Setup

The video doorbell solves a very everyday problem: someone rings and you do not know who is at the door. Instead of getting up, looking through the peephole or opening the door unprepared, a small screen or your smartphone shows in real time who rang. You can talk without opening, direct a parcel to a safe place or politely turn away an unwanted visitor without showing yourself. For people with limited mobility or for anyone who feels uneasy at the door, this is a noticeable relief.

Then there is the safety aspect. According to the police crime statistics, 78,436 (German police crime statistics) residential burglaries including attempts were recorded nationwide in 2024 – a slight increase over the previous year. The clearance rate was only 15.3 percent (German Federal Criminal Police Office), and 36.3 percent (German Federal Criminal Police Office) of the burglaries took place in broad daylight. A visible doorbell with a camera deters opportunistic offenders and documents who approaches the door. It does not replace a full security setup, but it is an affordable and effective building block. It is no coincidence that 16 percent (Bitkom) of people in Germany already use some form of intelligent video surveillance, and 61 percent (Bitkom) of smart home users deploy the technology specifically for more safety.

The third advantage is reachability while out. Anyone in the garden, at the office or on holiday still sees when someone rings and can respond. This is practical for parcel deliveries, reassuring during longer absences and helpful when relatives or care services are at the door. For this to work reliably, however, a stable internet connection right up to the front door is needed – a point that is often underestimated when planning Wi-Fi throughout the house.

Before buying, it is worth a quick look at your own door and the existing setup. Not every video doorbell fits every situation, and the choice later determines effort, image quality and data privacy. The most important questions can be clarified in a few minutes – we go through them together during a home visit and look at the existing bell wiring, door frame and Wi-Fi reception directly on site.

There are two basic designs. Battery-powered doorbells can be mounted almost anywhere because no wiring needs to be laid – but the battery has to be charged regularly depending on usage. Hardwired doorbells use the existing bell wiring and need no battery change, but require suitable wiring and possibly a transformer. Which option makes sense depends on the existing installation and the mounting location. In a tenancy, structural changes should be discussed with the landlord beforehand.

Good resolution helps to clearly recognize faces and parcels, even at dusk. More important than the pure megapixel count, however, is the field of view: it should be chosen so that your own front door and the immediate area in front of it are captured – no more. A field of view that is too wide quickly films the sidewalk or the neighbor's property as well and thereby leads straight into a legal problem. Many devices allow individual image areas to be permanently blacked out, so that only the permitted area is recorded. We pay particular attention to this function when choosing.

Perhaps the most important selection point is where the recordings are stored. Some devices store locally on a memory card or a base station in the house, others upload every recording to a cloud, often abroad and sometimes for an ongoing subscription. From a data privacy perspective, local storage is the more data-thrifty choice, because the recordings do not leave the house. Concerns about data security are widespread: 55 percent (Bitkom) of people fear being monitored through smart home applications, and 43 percent (Bitkom) worry about misuse of their data. We take these concerns seriously and prefer, where sensible, solutions with local storage.

With the video doorbell, data privacy is not a side topic but the decisive point. As soon as a camera records people recognizably, the rules of the General Data Protection Regulation apply, and the general right of personality comes into play. The principle is simple: you may film your own property and your own door, but not external areas such as the sidewalk, street or neighbor's property. This is exactly where most conflicts arise – and they can be avoided from the outset with the right aiming.

Case law here has been fairly clear for years. The German Federal Court of Justice has already ruled that a door camera which records exclusively when the bell is pressed and only for the immediate door area can, in principle, be permissible (German Federal Court of Justice). If, on the other hand, the camera permanently captures external areas as well, this can constitute a violation of personality rights and, in individual cases, even become criminally relevant – for instance through the protection of the most intimate private sphere under Section 201a (German Criminal Code). So what matters is not only whether filming takes place, but what and when.

Particular caution applies in a multi-family house. Here the hallway and the shared stairwell usually count as a communal area, so a doorbell camera may not simply capture the neighbors' entrance. Even a seemingly small co-recording of the sidewalk can be problematic under case law. We therefore aim the camera so that it reliably captures only the permitted area and use the device's blackout function where possible. This preserves the safety gain without infringing on others' rights. More about how we handle data is in our privacy policy.

A video doorbell is quickly ordered, but the trick lies in the details of mounting and setup. The height and angle determine the field of view and thus legal certainty. The connection to Wi-Fi determines image quality. And the setup of app, account and notifications determines whether the device is actually used in everyday life. This is exactly where self-made installations often fail – and exactly where our on-site service comes in.

During a home visit, we mount the doorbell in the right spot, aim the field of view so that only your own door is captured and, if needed, permanently black out external image areas. We then connect the device to the Wi-Fi and check whether the signal at the front door is strong enough for a smooth live image. If the signal is not sufficient, we discuss measures for stable Wi-Fi up to the front door, because without a good connection the image stutters and notifications arrive late.

After that, we set up the app and notifications so that you only receive the alerts you genuinely need, and we calmly explain how to call up the live image, talk and manage recordings. On request, we leave a simple, illustrated guide. This personal support is especially appreciated by older customers – we explore this topic further in our article on smart home for seniors. And if a question comes up later, a fixed contact person is there for you, not an anonymous call center.
