2N Door camera for 2N Helios - Installation manual - camera 9135210E - Manual (Page 2)

5. Connect the camera with the main board using the provided cable.
6. Select the camera mode
and video cable type via
jumpers. In the "Video
on during call“ mode,
the output is active
when a call is being
made to/from Helios.
When the call is
terminated, the video
remains active for about
7 seconds and then
switches off. Select the
"Permanently on"
mode for outdoor installations to avoid camera damage by air humidity. It is
because the camera is heated during operation and thus no moisture condensation can
occur.
7. Connect a video cable to the Video Output terminals on
the main board. If you use a twisted pair instead of
coax cable, it is not relevant which conductor leads to
which terminal but you are advised to record the
arrangement (+ / - mark, conductor colour). You will
use this information while installing the LCD monitor or
video server on the other cable end. If you use a coax
cable, connect its live wire to the + terminal and the
shield to the - terminal. If you use a UTP cable, connect the video signal to such two
conductors that are twisted together (making a twisted pair), never use two arbitrary
conductors. By connecting or disconnecting the jumper set the impedance match of the
video output for the coax cable or twisted pair.
8. Adjust the camera to desired viewing angle.
9. Insert cradle with the speaker back into the main board. Make sure that the cradle fits
properly in the appropriate holes.
10. Reassemble the door phone by mounting the plastic cover to the base and secure with
screws (4x) as well as placing back the metal cover.
