Audio On-Wall Set for 

MOBOTIX v25

Set for on-wall installation of 

MOBOTIX camera v25 (not included), 

for wall, ceiling or upright installation, 

includes microphone and speaker

•  Audio On-Wall Set for MOBOTIX cameras v25 (not included)

•  For concealed cabling from the rear or on-wall cabling from the side

•  Up to two interface boxes can be installed inside (e.g., MX-Input-Box, 

MX-Output-Box, MX-232-IO-Box, not included)

•  Vandalism-proof with optional vandalism set

Preparing the Audio On-Wall Set

Install the Cable Fitting (Optional)

If you are running the cables from the side 
and not from the rear, you should exchange 
the threaded plug against the supplied 
cable fitting. To unscrew the threaded plug, 
use a suitable coin.

Install the Interface Box Boards (Optional)

You can install the boards of up to two 
interface boxes inside the on-wall set. 
First, remove the lid of the interface box 
(three screws). Remove the two screws 
(red arrows in figure) using the supplied 
Torx wrench TX6 (Pos. 1.11) and remove 
the board.

Properly fasten the interface box boards 
using the same screws and the Torx wrench 
at the corresponding positions within the 
housing of the on-wall set.

Prepare the Installation of the On-Wall Set

Make sure that there is enough space for installing the Audio On-Wall Set 
and that you can access it from the rear or the side later on. The surface 
should be even and smooth so that the sealing lies flat properly.

Drill the holes using the drilling template on the back of this document and 
insert the supplied dowels, if required.

Guide the cables from the back (through 
the sealing disc of the on-wall set) or from 
the side. When guiding the cables from 
the back into the set, you need to cut 
the sealing disc as shown using a sharp 
knife (marked by a red cross in figure at 
the right). Only cut so far as to allow all 
cables and wires to pass.

through the camera sealing disc.

•  Place the sealing disc with the cables 

onto the on-wall set as shown. Make 
sure that the threaded inserts of the 
on-wall set (marked red in the figure) 
are showing through the sealing.
