Operation of the Device
To ring the bell and call up the image from the door camera unit on the videophone, press the button on the door camera
unit. Audio from outside will also be transmitted to the monitor.
To accept a call, press this button on the monitor:
To immediately call up the image from the door camera unit and CCTV camera, press this button:
Press the UNLOCK button to unlock the corresponding door or to open the gate.
You can enter the menu by pressing the middle button on the side of the monitor. There, you can set video and audio param-
eters, duration of lock/gate contact connection and menu language.
Maintenance of the Device
The device is low-maintenance. It is recommended, based on the state of the device, to occasionally wipe the device down
with a moistened cloth.
Warning! Before cleaning, the device must be disconnected from power!
FAQ
The device does not work
Check the cables and the connection of the power supply unit to the network.
If you extended the cable from the power adapter, check that the polarity is correct. Measure the adapter with a multimeter.
The output voltage on the connector should be 12 V DC (+/- 1V).
The image/sound is not clear, the device does not ring
Remove the monitor or the door camera unit and connect it using a short cable to eliminate the possibility of a disrupted
conductor in the house.
Then check the image and sound settings (brightness, contrast, colour, volume).
The lens steams up
This occurs mainly during cold weather, where condensation occurs due to the temperature difference between the wall
and the door camera unit itself. If water condenses on the lens, we recommend thoroughly drying the door camera unit
and adjusting the installation.
Spontaneous ringing
Spontaneous ringing is caused by moisture entering the door camera unit. Water short-circuits the contacts on the lock
switch and the device will start ringing on its own. We recommend dismounting the door camera unit, drying it thoroughly
and spraying it with water repellent for electronics.
High-pitched noise (feedback)
The source of feedback is the scattering of output sound from the door camera unit. The sound scatters and is fed back into
the microphone, where it is further amplified.
You can solve this by decreasing the microphone sensitivity and speaker volume.
In door units with adjustable elements, you can do this by turning the potentiometers.
In units without these control elements, you can reduce the microphone volume mechanically by a piece of soft foam.
The device does not open the lock
Check that the cabling is intact.
Measure the voltage on the lock terminals using a multimeter.
The lock requires a voltage of 12 V to trigger. If the value is lower, use stronger conductors for the lock control.
Sudden decrease in microphone sensitivity
Check the cleanliness of the microphone opening, or clean it gently with a thin, blunt object.
Be careful not to damage the microphone!
Do not dispose of electrical appliances as unsorted municipal waste; use sorted waste collection points. Contact local
authorities for up-to-date information about collection points. If electrical appliances are deposited in waste landfills,
hazardous substances may leak into the groundwater, enter the food chain and harm your health.
