2.3 Connections / Tact Switch Operation & Lens Control
All are on the flying lead of the camera. As default, the camera is set to TVI in HD mode
1. Video Out (BNC)
2. 12VDC/24VAC power connection (12VDC is polarity dependant)
On the inside of the VVRD28V12MHDA(IR)W, there is a removable top case, which provides
access to the tact switch for the OSD and a Video Out mode switch (HD / CVBS).
Video Out mode switch (HD / CVBS)
Select between the video output mode from the BNC between HD (TVI/AHD) and CVBS
(1000TVL)
Switching the HD output between TVI & AHD
With the Video Out mode switch in the HD position, TVI is the default output. If you require
AHD, then without the OSD being on, push and hold the Left Button for c.5 secs, this puts
the camera into AHD (the camera needs to be powered). The same process should be
applied to put back into TVI mode, but using the Right Button.
Tact Switch for OSD control
1. Left (push and hold for c.5secs for AHD)
2. Up
3. Enter (to access OSD)
4. Right (push and hold for c.5secs for TVI)
5. Down
Tact Switch for motorized lens control.
Without being in the OSD:
Up
– Zoom in
Down
– Zoom out
The lens will then autofocus the lens based on the overall scene being viewed.
NOTES:
The camera is only able to output one signal at a time.
If your DVR supports coax telemetry, for TVI select TVI / Hik-C. For AHD select
Fastrax-C
– this will give menu access from the DVR (you will need to refer to the
DVR manual for the commands).
