VIDEOS

Need help with the installation? Be sure to watch our installation videos which can be found on http://www.doorbird.com/support
Each individual step of the installation is clearly documented in the videos.

INSTALLATION

All steps below should be carried out carefully by a competent adult, taking into consideration any applicable safety regulations. Should you have any questions, please contact us or a competent specialist directly. Please ensure that all wires used for the installation are undamaged along their entire length and approved for this type of use.

Network speed and network components

Please ensure that the upload speed of your Internet connection is at least 0.5 Mbps. You can also carry out a speed test at any time via the DoorBird app. The user experience is only as good as your network speed, network sta- bility and quality of your network components, such as your Internet router and WiFi access points or WiFi repeaters. Please also make sure that your net- work components are no older than two years old, have been manufactured by a well-known manufacturer, and have the latest firmware installed.
Should these requirements not be fulfilled, it may happen, for example that the performance of audio and video is poor or push notifications are delayed or do not arrive on your smartphone or tablet at all. High-speed Internet (via landline): DSL, cable or optical fibre Network: 802.11b/g/n 2.4 GHz or Ethernet, with DHCP

STEP 1: SWITCHING OFF POWER

Switch off the power to all wires leading to the assembly location, i.e. the door chime, electric door opener, power supply unit for the video door station etc..

STEP 2: DISMANTLING THE EXISTING DOORBELL

Should there already be a doorbell on the exterior wall of the house, please dismantle it.

STEP 3: DETERMINING THE ASSEMBLY LOCATION

The video door station uses an ultra wide-angle hemispheric lens so that even when the person is a minimum distance of 50 cm (19.68 inches) away from the video door station, a low installation height is sufficient. The lens is therefore not mechanically adjustable. The camera lens should be located at an altitude of at least 145 cm (57 inches). You may check this prior to the final mounting. Press the mounting plate against the wall at the desired installation site and mark the boreholes with a pencil. Remove the mounting plate again. Ensure that no cables are to be found in the wall behind the boreholes When choosing the assembly location, consider the lighting conditions. Avoid direct sunlight, direct backlight and reflective surfaces

****Do not expose the device to direct sunlight. The housing temperature can exceed the maximum allowed temperature limit. This can result in damage of electric and mechanic components of the device and injuries especially when touching exterior parts of the device. White and bright silver-colored front plates absorb less sunlight than dark ones.

****An image sensor must not be exposed to direct sunlight for an extended period of time. Direct sunlight will “blind” the camera and may permanently bleach the small color filters on the image sensor chip.

****Any defects caused by direct sunlight is not covered by warranty.

STEP 4: POWER SUPPLY

The video door station can be powered by two simple doorbell wires using the power-supply unit (mains adaptor) supplied with it or via PoE (Power over Ethernet) using a network cable. The video door station can alternatively also be supplied with a DIN-rail power supply unit that you can obtain from us directly.
The video door station does not use battery power. The use of a mains power supply permits the transmission and display of on-demand live video at any time and not only if a visitor has pressed the doorbell.

Power supply using the power-supply unit (mains adaptor)

Two insulated wires are required to power the video door station by plugging it into the mains. These wires are normally already there and are freely accessible once you have removed the previous doorbell. Only use the power supply unit provided along with the video door station, or a DIN-rail power supply unit that you can obtain from us separately, since this has been spe- cially stabilized electrically and is equipped with an integrated audio interfe- rence reduction device. Other power supply units may destroy the video door station or cause poor transmission quality. The warranty automatically expi- res if you use a different power supply unit. The power supply unit is plugged into a wall socket inside your house, usually where the two wires from your previous doorbell come out of the wall in the interior of the house.
Do not plug the power supply unit into the wall socket yet. Connect the po- wer supply unit inside the house with the crimp connector provided and the two wires that you would like to use to power the device.

Power supply via PoE (as an alternative)

To power the video door station via a PoE switch (e.g. D-Link DGS-1008P) or PoE injector (e.g. TP-Link TL-PoE150S) in accordance with the PoE standard IEEE 802.3af Mode A, the four wires bearing the numbers 1, 2, 3 and 6 of a Cat.5 cable or better are to be used. A Cat.5 cable or better must be used as network signals can only be transmitted over completely insulated, shielded and twisted cables. If you use PoE as a source of power, the WiFi interface of the video door station is automatically inactive, and the four wires for PoE then simultaneously form the data link. The video door station won’t start if your PoE Switch or PoE injector does not support the PoE Standard IEEE 802.3af Mode A (see Diagnostic-LED and Diagnostic-Sounds).

1. Disconnect the PoE switch or PoE injector from the power
2. Place the network cable in the installation site of the video door

Do not combine the power supply from the power supply unit (mains adaptor) with the power supply via PoE.

STEP 5: FURTHER CONNECTIONS (OPTIONAL)

If desired, connect additional wires to the installation site of the video door station. The wires or connection options mentioned in this section are optional.

Connecting the unit to a network

You can connect the video door station to your existing network via WiFi, or alternatively use a network cable (Ethernet). For reasons of network stability, we principally recommend using a network cable, as WiFi is sensitive to interference (range, house walls acting as shields, relia- bility of performance, third party WiFi networks, wireless transmitters causing interference in the area, etc.). The video door station can be powered by PoE or using the power supply unit provided. If you use PoE as a source of power, the WiFi interface of the video door station remains inactive.
Use only four wires (1, 2, 3 and 6) of a network cable that meets the Cat.5 standard or a better one. The other four wires of the network cable (4, 5, 7 and 8) are not required. Connect the network cable in the house to your Internet router or to your PoE switch or PoE injector that is connected to your Internet router.

Be sure to use four insulated, shielded and twisted wires of a network cable in accordance with the Cat.5 standard or better.

Electric door openers

The video door station has a zero-potential relay contact for a standardised electric door, gate or garage opener (two wires). There is the possibility of switching on all electric door openers that work at a maximum power of 1 A in the voltage range of up to 24 V (AC/DC). The video door station does not provide its own power supply for the electric door opener. This is provided through the separate power supply of the electric door opener. You can learn more about the installation of the power supply from the instruction manual or technical specifications of your door opener. Should you have any questions about this, please contact the manufacturer of your door opener. You can find compatible electric door opener and a sample wiring diagram at www.doorbird.com/support

Two insulated wires.

Conventional electric door chime

If someone rings your video door station, you will imme- diately receive a push notification with sound/vibration on your smartphone or tablet. In addition the video door station comes with a zero-potential relay contact for connecting a conventional electric door chime inside the building. The relay contact can be used to activate the separate operating voltage of the door chime or the door chime via its trigger input. If the operating voltage of the door chime is activated, it should not be greater than 24 V (AC/DC). The power consumption should not exceed 1A. The video door station does not provide its own power supply for the door chime. This is provided through the separate power supply of your conventional door chime. Should you have any questions, please con- tact the manufacturer of your door chime. You can find compatible door chimes and a sample wiring diagram at www.doorbird.com/support
Two insulated wires

Conventional door opener button

If an electric door opener is connected to the video door station, the door opener can be opened by App and also be directly controlled via a zero- potential button to be found in the interior of the building, i.e. a door opening button. In addition, the door opener button is to be connected to the connection terminal provided. Please make sure to add no extra voltage on that contact. You can find compatible door opener buttons and a sample wiring diagram on www.doorbird.com/support

STEP 6: (OPTIONAL) ATTACHING THE MOUNTING HOUSING

Position the mounting housing against the exterior wall of the house and use the screws provided to position it in the dowels or on the wall. Feed the wires that you want to connect to the Video Door Station through the hole provided in the mounting housing. Attach the mounting housing. The attachment of the mounting housing for the Video Door Station series D20x is individually adapted to the assembly location. If necessary, call a professional for help

Most common ways to attach the mounting housing:

housing if necessary
D204| With screws and / or grout. You have to drill holes in the mounting housing if necessary
D205| Depends on the environment / integration

STEP 7: PREPARING THE WIRES

Remove about 5 mm of insulation material at the end of the wires that you would like to connect to the Video Door Station.

STEP 8: CONNECTING THE WIRES

It is possible to connect the Video Door Station conveniently and safely via the colour-coded cable harness on the reverse of the Video Door Station. Please use appropriate crimp connectors or terminal strips to connect the supplied cables with your wires. The accompanying crimp connectors are weatherproof and are equipped with heat-shrink tubing which can be sealed after assembly by, for example, carefully using a heat gun.

Please take care when connecting the wires. Connecting the wires the wrong way may destroy the Video Door Station.

STEP 9: ANTENNAS

Screw the external 2.4 GHz WiFi antenna using an Antenna extension cable to the designated position on the back of the Video Door Station. Screw also the external 433 MHz RFID antenna using an Antenna extension cable to the designated position on the back of the Video Door Station. We recommend to feed the antennas out of the housing for better reception and transmission power, because it is made of metal (shields). If you don’t want to use WiFi or RFID at all, you don’t have to screw the respective antenna to the designa- ted position.

STEP 10: FINAL ASSEMBLY

Applies only to DoorBird Video Door Station D201 and D202: Screw the front panel with the attached Video Door Station to the mounting housing with the safety screws and the appropriate tool. Applies only to DoorBird Video Door Station D203 and D204: Mount the Video Door Station with appro- priate screws/dowels on the wall/fence. D205: Depends on the environment / integration. If necessary, call a professional for help.

STEP 11: ACTIVATING THE VIDEO DOOR STATION

Switch on the power to the wires leading to the assembly location again.

You can see whether you have connected the power supply properly from the Diagnostic LED (it lights up once the power has been connected correctly

for up to five minutes and continuously in night-vision mode). The video door station is ready for operation (booting up process, any software updates, etc.) once it has emitted a short diagnosis sound from the integrated loudspeaker. This may last for up to 5 minutes. Should you not hear a beep, please check the power supply. Please also check whether you have used a wall- plug power-supply and not PoE and whether you have connected the positive pole and negative pole to the video door station correctly.

STEP 12: DOWNLOADING AND INSTALLING THE APP

Download the „DoorBird“ app by Bird Home Automation onto your mobile device from the Apple app store or Google Play store. You can always find the most up-to-date version of the App manual on www.doorbird.com/support

If you use WiFi for connecting the video door station to your Internet router, first go to „Settings > WiFi Setup“ and follow the instructions.
If you have finished the WiFi set-up or have connected the video door station to your Internet router by means of a network cable, go to „Settings > Add device“ and click on the QR code icon in the „User“ field. Scan the user QR code found on the „Digital Passport“ that accompanies the video door station.
If you have problems adding the video door station to the App please check
if the video door station is online ( www.doorbird.com/checkonline ).
If the video door station is not online, please check the WiFi or network cable connection again.
Since Apple uses very high quality microphones, loudspeakers and digital audio components that are perfectly in tune with one another, the voice quality with an iPhone or iPad is usually noticeably better than with an Android smartphone or Android tablet.

DIAGNOSTIC-LED
