2N® LiftIP with an external IP camera (Revotech) - direct call to 2N® Lift8 Communicator

This FAQ describes how to setup direct call between 2N® LiftIP and 2N® Lift8 Communicator with a feed from a Revotech IP camera.


* This parameter can be set via the voice menu (incoming call to 2N® LiftIP unit).

** This parameter can only be set via the 2N® LiftIP Service Tool.

A list of all parameters that can be configured can be seen in the manual: Programming Function Survey

In the Lift8 manual you can find how to get the 2N® Lift8 Communicator working: https://wiki.2n.cz/l8um/latest/en/8-communicator

Please keep in mind that if you will disable confirmation for alarm calls, then you are doing this at your own risk as there is no human interaction!

1) Connection to 2N® LiftIP

Connect to your 2N® LiftIP unit using 2N® LiftIP Service Tool which you can download - here

  • It is necessary to use the 2N® LiftIP Service Tool, as VoIP parameters can't be set via the voice menu (incoming call to 2N® LiftIP)

You can connect directly by choosing TCP and filling in the correct IP addressPort and Password
If you don't know the IP address, please use the FAQ - How to get IP address of lift communicator 2N® LiftIP.
If you need to set Static IP address or DHCP please use this FAQ - Static IP address - How to set up static IP address on 2N® LiftIP

2) How to set the alarm call destination

Go to Configuration - Parameters - Alarm Call -> and set following parameters:

011 =* IP address and SIP port of the 2N® Lift8 Communicator - in our example we use ""
018 =* Count of automatic dialling cycles for ALARM (011-016) * - when the destination doesn't pickup, it calls again depending on the count of cycles you set

111 =* Alarm call memory confirmation mode  - defines how the call is confirmed after pick-up
  x1x = Alarm button (1-6)
  xx1 = Type of confirmation 

  • 1 = with DTMF confirmation (1)
  • 2 = with pick-up confirmation (for GSM/UMTS/VoIP only) - no confirmation, just pick-up the handset
  • 3 = CPC Antenna
  • 4 = CPC Kone
  • 5 = P100
  • 6 = DTMF auto detection (CPC Antenna/P100)
  • 7 = CPC Antenna 2N ext
  • 8 = CPC Kone 2N ext
  • 9 = P100 2N ext

You can find all parameters in the Programming Function Survey

3) How to set the video stream from the Revotech camera

5) Setting of the 2N® Lift8 Communicator

4) Run the 2N® Lift8 Communicator - see in the manual, please: https://wiki.2n.cz/l8um/latest/en/8-communicator

    and as the SIP port put the same one as for the alarm call number in the 2N® LiftIP Service Tool - in our case - 5070:

Now the 2N® Lift8 Communicator is ready to answer the alarm call from the 2N® LiftIP together with the stream of the IP camera.

If the camera picture wouldn't appear in the 2N® Lift8 Communicator, let disconnect WiFi connection on the PC.
