Frequently Asked Questions

 iOS and Android Version, Hardware

During App development we must always operate under the specifications and guidelines provided by Apple and Google, which suggests that, among other things, that apps and app updates for the App Store and Google Play Store must always be developed using the latest iOS and Android versions. This of course also means that new apps are reserved for the current smartphone operating systems and hardware. Because our products are also security related, we advise that you always use the latest smartphone with the most recently updated version of iOS or Android.

You can find the current minimum requirements for the app in the Apple App- or Google PlayStore depending on your operating system. 

 Integration with Apple HomeKit

We are still in active talks with Apple regarding the "HomeKit" integration. Currently there is no DoorBird IP Video Door Station available with "HomeKit" integration. 

We would like to offer to keep you up to date regarding this topic with our newsletter.

 Electric Door Opener Tamper Protection

In general, any electric door opener connected by direct wiring of the live wire to a door intercom can be tampered with. This applies to every door intercom (for physical reasons) and is also almost exclusively how electric door openers are installed worldwide. 

For greater security we recommend that you protect the electric door opener with a tamper contact which has a remote safety relay. We do offer our own door controller A1081 as a solution for this topic in our shop. 

Alternatively you can also encrypt the door opener signal via IP and send it to the door opener via your home automation system. We offer a comprehensive API for integration into third-party systems:

 RFID function (D10x/D20x/D21x series)

D10x/D20x series:

The D10x/D20x series features a built-in 433 MHz transceiver (sender, receiver) and was planned to use it for external Radio-frequency identification sensors/senders such as external remotes (as you know e.g. from garage systems) and external motion sensors. These were never designed to be used for access control using cards of key fobs because they do not support the right frequency.However because of the lack of support from third party systems we did not fully launch this feature yet. 

D21x series: 

The D21x series features a built-in 125 KHz RFID reader for access control (Active Reader Passive Tag (ARPT) system), as specified in ISO/IEC 18000-2:2009 Part 2 which makes them compatible with other third party key fobs and card entry systems.

A maximum of up to 100 keyfobs can be registered.

D11x series:

The D11x series does not have an integrated RFID module.

 Push messages are not displayed or only delayed

As soon as a visitor rings the device a message gets send directly to the Apple / Google push server. In general the operating system of the mobile end device (iOS, Android) manages reception and display of a push notification. The DoorBird App functions as every other App and it usually takes 2-3 seconds until the push notification shows up on your mobile device.

The most common examples are (sorted by frequency of occurrence):

A network component within your network goes into sleeping mode and awakes only through activity of your mobile device again. Solution: Update the firmware of the Wi-Fi components (e.g. router or repeater) in your network

  • The operating system restricts the background activity of the DoorBird app and thus prevents push messages from being delivered promptly. Under Android, relevant settings can usually be found under Settings → Apps → DoorBird → Battery
  • The mobile device’s internet connection is unstable (Wi-Fi or mobile data). Solution: Improve the connectivity of the mobile device. The internet speed booked from the mobile phone service provider is not sufficient information.
  • The device’s connection to the internet is unstable (Wi-Fi or Ethernet). Solution: Improve the connectivity of the device. The internet speed booked from the internet provider is not sufficient information.
  • The mobile device is in sleep or “do not disturb” mode. Solution: Our DoorBird App does not overrule you’re the system settings of your mobile device. Deactivate this mode to receive push notifications.
  • The mobile phone operating system does have battery saver settings activated that automatically end apps and processes that are running in the background. Solution: Add the DoorBird App to the list of exceptions so it is not affected by this by the battery saver.
  • There are apps installed on the mobile device that fit into category battery saver, cache cleaner, system optimizer. Apps in this category end processes running in the background. Solution: Add the DoorBird App to the list of exceptions so this app does not interfere with the DoorBird App
  • Push notifications for events are not activated in the DoorBird App settings. Solution: Open the DoorBird App → Settings → click on the added device (e.g. aabbcc0001) → Push Notifications → Doorbell → Activate

 Video door station cannot be added

The QR code for the stored users on the “Digital Passport” document is only working for as long as the associated user in the Administration area of the DoorBird has not been deleted/changed. When the video door station is connected to the Internet (see, but the App gives an error notice when a device is added or you lost the connection to a DoorBird that was already connected to your App, in 99 % of the cases, the stored user “...0001” on the “Digital Passport” document (the one for which the QR code stands) does not exist on the device or the password has been changed (see “DoorBird App -> Settings -> Administration“). 

a) If the user does not exist on the device, please create a new user (see “DoorBird App -> Settings -> Administration”), note down username and password and connect the DoorBird to the App manually. 

b) If the password has been changed, please note down the username and password of the user and connect the DoorBird to the App manually.

(Hint: You can use the "share user data" function to generate a new QR code)


In case the administration login does not work, we recommend a reset to factory defaults:

 General info about the App

Please make sure that you are using the latest version of Door Bird App. It often happens that requests relate to outdated app versions. Please also make sure to restart your smartphone/tablet as some issues are related to the operating system. 



 Motion Detector

For all devices that have installed a motion sensor, the sensor can be activated and configured in the DoorBird App administration (DoorBird App -> Settings -> Administration -> Login -> Motion Sensor). If the motion sensor is activated and you would like to receive push messages for events, these must be activated separately in the settings for the mobile device (DoorBird App -> Settings -> click on the added device, e.g. device0001 -> push messages -> motion).


In our experience, Devolo/HomePlug/Powerline adaptors are unfortunately unsuitable for for door communication purposes because they do not transfer all the data correctly. We also know of similar experiences with competing products. Unfortunately, we have no influence on this technology.

 Cloud Recording

All DoorBird IP video door stations come with an integrated free image history.

You can find further information about our "Cloud Recording" feature on the following page:

 Video recording / Third party systems / Integration

We offer a comprehensive open API for any kind of third-party integration (e.g. NAS, NVR, VMS, Home Automation, Smart Home etc.). You can find further information online:

In addition, we already offer instructions for many interesting integrations on our DoorBird connect pages:

 Dimensions of a specific device

You can find the dimensions and further information in the provided data sheets below each product in our webshop:

Do not hesitate to get in touch if you have any questions regarding our products:



 Required Internet Speed

The DoorBird requires High Speed Internet (Landline): DSL, Cable or Fiber, with DHCP. Internet Upload Speed minimum 0,5 mbit/s or faster. The faster the Internet, the better the image and audio quality. Please do not connect the DoorBird to an 3G/4G/LTE router (Stability, Latency, TCP/UDP package loss).

 Weatherproof design

The DoorBird has been conceived for use outdoors in harsh environmental conditions. Therefore it has been certified in accordance with the IP65 outdoor industry standard and has been accredited to meet the requirements of Protection Class A1 for rain and snow (which is ,for example, the standard in Northern Europe, North America and Canada).

 Sequence of notification of mobile devices

The doorbell’s signal is very time-critical. It is therefore not practical to set up a sequence for smartphones/tablets that is executed successively if a visitor rings the doorbell. All users will be simultaneously notified on their smartphones and will be able to see the visitor live.. Alsoeach remaining user is notified if one user is already talking to the visitor. If a user were only to receive a signal 30 to 60 seconds later, i.e. if there were no response from a user previously notified, the visitor would already long have left again.

 Conventional door opener button

Our models support the use of a conventional door release button inside the house to open the front door, garage, etc. without a smartphone or tablet. Please make sure that the button isvoltage-free, e.g.

Please make sure to follow the instructions and the connection diagram in the manual.

 Mounting height / lens

All models of our IP video door station use a hemispherical ultra-wide-angle lens. This means that a low mounting height is sufficient to display a person in front of a device at minimum distance (~ 50 cm / 20 in).

It is not possible to rotate the camera module or mechanically adjust the lens on any model, so horizontal installation of the IP video door station is not possible.

The camera lens should be installed at a height of at least 145 cm / 57 in. 


D11 series: Due to its compact design, this series is ideal for locations where other models could not be installed. For this purpose, we offer additional mounting brackets in our web shop to cope with complicated installation conditions.

Please always check the optimum installation height for your location before installation. 

 Cloud Service

Our products are cloud-based solutions (see also NEST, Dropbox, etc.). For reasons of reliability and security no port forwarding is conducted through the internet (using NAT or DynDNS). Our products establish an encrypted VPN tunnel connection to our cloud server (located in a highly secured data centre in Germany). 

Our products rely on the same secure communications technology used by financial institutions for online banking (SSL). The remote access via our cloud-server is free of charge. 

It is not technically possible to use our products autonomously without internet access or without access to our cloud servers, as otherwise key functionality like, for example, push notifications (special server security certificates required by Apple and Google), remote access, periodic free software updates etc. would not be available. 

The entire solution is tested and approved by the responsible state office of Germany for Data Privacy and Data Security. 

If you want to work without a cloud server you may use an autarkic IP system from e.g. Siedle or Gira, which of course do not provide the same functionality. As a provider of intelligent and convenient Smart Home solutions we do not offer products without connection to our Cloud-Server. It is not possible to use of third-party Cloud Services e.g. from Google Drive, ownCloud, Dropbox, Microsoft Azure, Amazon S3 (for security reasons!).

 Windows / macOS app or browser access

Our IP video door stations support the secure and smooth use with popular smartphones and tablets (iOS, Android) or our IP video indoor station A1101.

On other platforms we additionally offer the possibility for modern web browsers to configure the device using the web administration tool as well as watching the live view using the HTML5 widget.


Web administration tool:


  Fixed video internal unit - A1101

As fixed internal video unit we recommend the use of our compact IP video indoor station A1101 in conjunction with all DoorBird IP video door stations. The IP video indoor station A1101 comes with a 4“ True Color Display Touch Screen with scratch-resistant tempered Gorilla® glass and excellent audio quality.  

In addition we do offer the table stand A8003 which is designed for using the IP video indoor station A1101 on tables and sideboards. 

You can find both products in our webshop:

 Number of end devices

The DoorBird can be connected to up to 8 mobile devices for each bell push button (iOS, Android). 

When someone rings at your door, a push notification is sent to all linked end devices, all users can view the video simultaneously, though only one user may speak to the visitor at a time (the other users will receive a notification that it is engaged).

 Anti-theft protection

Our DoorBird IP video door stations are protected against theft with special security screws, like any other high-quality door intercom system.

Current there are only two known cases where a DoorBird IP video door station has been was stolen. In case of theft the device can be completely locked. 

In case of theft, you can send us of copy of the official police report. We will find a solution for you. 

 Additional Cameras / Integration of third-party cameras into the Doorbird App

The BirdGuard B101 is an additional camera that can be operated in our DoorBird App. 

The integration of third-party cameras is not possible in conjunction with the DoorBird App. 


You can easily integrate the BirdGuard B101 as well as our DoorBird IP video door stations into third-party systems. 

We offer further information on integrations into third-party systems:


 Mounting on a thermal protection wall

There is a special rawlplug to use when mounting components on a thermal protection wall, e.g. this product: 

Please clarify this with the manufacturer of your insulation to find out exactly which rawlplug is recommended to be used in this instance. You can find the required diameter of the screws listed in the DoorBird mounting guide.

 Connection of an electronic door/garage/gate opener or strike

Our IP video doorstations allow for connection options for standardised electric door, gate or garage openers (two wires). It is possible to connect all door openers that can be used in the range up to a maximum of 24 V (AC/DC) and 1 A. More information and a schematic diagram can be found in the manual of the respective model. 

The IP video doorstations do not provide a power supply for the opener. A separate power supply must be provided. For a suitable power supply and further information, please contact the manufacturer of your door opener. 

Door strike example:

 Static IP-Address / DHCP

We have not built-in a way to manually configure static IP address details into our firmware. If you must set one of our network devices to work with static IP-address details, you should set this comfortably in your DHCP server / router for the certain MAC address of our network device. Configuring static IP-address details into a device without using DHCP leads to well known problems in practice, so this is never recommended in a modern network.


All DoorBird IP video door stations have a built-in SIP module for integration with various SIP phones and Home-Automation systems to meet advanced audio and video communication needs. DoorBird therefore provides the possibility to perform SIP integrations through a SIP interface that can be accessed via the App (DoorBird App -> Settings -> Administration -> Login -> SIP settings). As SIP is not standardized, any integration has to be configured individually. This is only possible with considerable effort and DoorBird does not provide any support on individual SIP integrations. DoorBird undertakes ongoing development efforts to integrate SIP. 

All compatible SIP devices and installation manuals can be found here:

 Connectivity problem in a mobile phone network?

In some regions mobile phone network operators block the access to certain services or on standard ports (e.g. HTTP [80], HTTPS [433]), e.g. by using a passive proxy server or because of erroneous routing (normally a temporary problem). This case is very rare but it cannot be bypassed without knowing how the mobile phone network operator is blocking which data. A simple work-around for checking is the temporary use of a VPN service, e.g. (free for a short test).  

 If a connection is possible using a VPN service and you get in touch with your mobile network operator, please forward this information:

 WiFi / WiFi problems / ethernet cable


For the devices with integrated WLAN module, we have explicitly included the point "WLAN range" in the product design. Our devices therefore deliver significantly better results than relevant competitor products (including smartlocks). 

Unfortunatly there are always environments where WiFi does not work satisfactorily. We have no influence on this, as we already use the maximum allowed antenna radiation in the EU, Canada and USA. Our devices only use the 2.4 GHz frequency range (WiFi channels 1-13 / 2401-2483 MHz). WiFi in the 5 GHz frequency range can allow higher speeds but has the disadvantage of a smaller range (Our IP video doorstations on needs 0.5 Mbit/s).

In general for reasons of stability (availability, reliability) and possible delays for push messages we generally recommend connecting the devices via network cable.


This series has no integrated WiFi module and is operated exclusively via network cable.

All models:

If only two wires (and no network cable) are available at the installation location, we offer a solution in our shop with the 2-wire Ethernet PoE converter A1071.

 Multiple video door station

The DoorBird app supports up 10 DoorBird Video Door Stations and additional BirdGuard cameras. 

You can switch backwards and forwards between the video door stations and additional cameras within the app by tapping using the tip of your finger.

 Reset to factory defaults / Digital Passport lost

The following models can be reset to factory settings:


No login credentials (Digital Passport) are required for resetting to factory settings, nor does the device have to be previously set up on the mobile device.


Please go to the "Reset to factory settings" in the DoorBird app under settings and then follow the step-by-step instructions. Please keep in mind that DoorBird must be online via network cable for the procedure. Also the iOS or Android smartphone/tablet from which you carry out the reset has to be on the same network as DoorBird.

At the end of the procedure you will receive a new "Digital Passport" document. 

Please note that you must leave the device untouched for 15 minutes after a successful reset, as the firmware will also be installed on the device again. 


The process is also available as video:

 General - Power supply

You can power up our IP video door stations or our add-on products using one of the following options: 

  1. the power supply included in the retail package (works from 110 to 240 V and comes with adapters worldwide use)
  2. Power over Ethernet switch or injector (PoE 802.3af Mode-A, e.g. using the DoorBird Gigabit PoE Injector A1091, available in our web shop below "Accessories")
  3. optional DoorBird DIN rail power supply (separately available in our web shop below "Accessories")


For the correct selection of the DIN rail power supply please check the following article:

For warranty reasons, our devices may only be operated with power supply units purchased directly from us, as these are individually tested and specially certified.

The power supply via PoE is excluded as it is standardized worldwide:

 iOS or Android updates / push notifications

After an update of the smartphone operating system, it may happen that push notifications for your events are no longer delivered. The DoorBird app itself has no influence on this. 

Please open the DoorBird App and go to settings (do not enter the adminstration), click on the added door station listed in devices (e.g. station0001) and then click on the red “DELETE” button. Please then restart your mobile device and add the device again using your credentials. 

 Can I transmit network data and power over two simple bell wires?

We generally recommend a hard-wired connection between the IP video door station and the Internet router, as this is almost maintenance- and trouble-free compared to a Wi-Fi connection. 

The installation can be realized with a network cable (Cat.5 or better) to transport both network data and power (PoE). 


If an installation via network cable is not possible and only simple bell wire is available on site, our 2-Wire Ethernet PoE Converter A1071 offers a good solution and can transport both network data and power (PoE) over two simple bell wires on a distance up to 80 meters (3150 in).  

Although the 2-Wire Ethernet PoE Converter A1071 is the smallest device in its class, the receiver does not fit into the housing of current models. Some space can be provided for installation behind the housing, or alternatively a small housing suitable for outdoor use can be mounted for the receiver. 


Further information is available in the manual on our support page:

 Apple Watch

If you install the DoorBird app on an iOS device, a paired Apple Watch will also work. It is possible to receive push messages on the watch or open the door. 

Unfortunately audio communication via Apple Watch is technically not possible, as this is restricted by Apple. As soon as Apple offers the interface, we will implement it.

Please keep in mind that push notifications are only displayed on one of the devices after pairing:

 Using third-party call buttons with the DoorBird IP video door station

D10x/D11x/D20x series: For warranty reasons it is not possible to operate the device with third-party call buttons.

D21x series: It is possible to use the D2100E (Engineering Edition for integration purposes) in conjunction with our product MTM14E for using up to 14 third-party call buttons. 

Please make sure to check the data sheet of the products in our webshop and the additional instructions for individual panels:

 Android TV

We do not support Android TV because there is still a very low demand and the distribution also is very limited, e.g. LG relies on webOS, Samsung on Tizen. 

 firmware updates

Our devices receive automatic firmware updates on a regular basis to introduce new features or match with the latest changes introduce on new iOS/Android updates. 

As soon as we start the roll out for a new firmware, we inform about the changes here:

An update always only affects the product series that are shown under "Products affected".


The roll-out usually happens in update waves, which means that not all devices receive the latest firmware at the same time and it can take up to a few weeks before all devices are updated. 

In addition to our firmware changelog, we also inform about new features in the app changelog in the AppStore/PlayStore for the DoorBird App.

It is possible to check anytime whether the device does run on the latest firmware on the check-online pages:


 Amazon Alexa / Amazon Echo

We are currently working on an integration of our products into Amazon Alexa / Amazon Echo. Sign up for our newsletter to find out when this feature is available.

 Which menu languages does the D21DKH and D21DKV support on the outdoor display (resident directory etc.)?

The menu language of the outdoor display of the IP Video door stations D21DKH and D21DKV can currently be set via the DoorBird App administration area to the following languages :

  • German
  • English
  • French
  • Spanish
  • Italian
  • Russian

 Illumination - Bell push button

D10x/D11x/D20x series:

For all models of the D10x/D20x series the illumination of the push buttons can be configured. 

The setting "On" sets a permanent illumination, the setting "Off" deactivates the illumination and the setting "Automatic" sets illumination when darkness is detected. 

The option to change this setting is available in the administration of the DoorBird App ("Button LED"). 

Regardless of the settings, illumination occurs within the first five minutes after a restart. 


D21x series:

All models of the D21x series have permanently illuminated buttons.

We do not offer the option to change the behaviour. 

 Connection status messages coming from the speaker of DoorBird IP video door station

The DoorBird IP video door station does notify you about the connection status after start-up. Up to three signal tones and a voice announcement in English are played.

3 signal tones and the announcement "No Network" indicate that there is no connection to the local network (DHCP, wiring etc.).

2 signal tones and the announcement "No Internet" indicate that an IPv4 address was assigned via DHCP and a connection to the local network exists, but that no Internet connection is possible (Internet outage, firewall settings).

1 signal tone and the announcement "Successfully connected to Internet" indicate that the DoorBird IP video door station has connected to the DoorBird cloud. 

The volume for these diagnostic sounds can be switched between "Standard" and "Silent" in the administration of the DoorBird app. (DoorBird App -> Settings -> Administration -> Login -> Expert settings -> System diagnostics volume).

 Is the brightness of the display of the IP Video Indoor Station A1101 configurable?

The display is optimized for durability and is already configured for maximum brightness.

 Wired outdoor network connection

If you have a wired network connection for a network camera, access control or door intercom (regardless of the manufacturer) in the outdoor area, it may be advisable to additionally secure this connection in case of security concerns.

For this use case, a firewall can be configured separately to secure the connection at the connected LAN port. The essential requirement for our products is that a direct Internet connection to * on ports 80 and 443 must be possible.

A complete overview of the ports used can be found in the following document:

Please note that we cannot provide product advice for routers or firewalls. The standard models available from your Internet service provider do not always offer such configurations. We recommend to get in touch with your local IT and network specialist who can advise you on products and configure the firewall accordingly.

 A1101 - Summer and winter time

In many regions of the world, a time change happens twice a year between summer and winter time. 

The IP video indoor station A1101 performs it automatically, but it can take up to 24 hours depending on the region.

 Comparison D11x / D21x / D10x

The D1101V is our latest and smallest model. This IP Video Door Station is WiFi-enabled, has one switching relay and a Full HD camera with an integrated 1080p Sony image sensor. The D1101V is available in two versions – separately for surface- and flush-mounting.

The D2101V is bigger in size, has two switching relays and an integrated RFID reader for access control. This model is operated exclusively via a network cable. IP Video Door Stations for single-family residences and buildings with up to three units are available in over 50 colors and surfaces. We also have models equipped with more components such as keypad, display or info module. A flush-mounting housing is always included, a surface-mounting housing is sold separately.


The D11x and D10x product lines are compared in the following document:

 App - Dark Mode

The Doorbird app supports the global "Dark Mode" of mobile devices. It is available since iOS 13 / Android 10 and can be activated in the display settings of the mobile device.

We do not offer a separate setting for the "Dark Mode" in the DoorBird app.

 iOS 14 - Settings - Allow local network

With the latest update to iOS 14 new data privacy settings were introduced. 


In order for the DoorBird app to communicate with our devices on the local network, this must be enabled as a permission under iOS. 

When the app is installed for the first time, a pop-up will appear: "DoorBird would like to find and connect to devices in your local network."

This setting must be confirmed with "OK":


The option can be changed later: 

iOS settings → scroll down → DoorBird → activate the slider for "local network"
