Powering the Camera
The SEE875 draws 12V DC 500mA when IRs are on, and power consumption is rated at 6 watts. It
should be noted that extra headroom is required when the camera is first powered up so we
recommend connecting it to a 12v DC regulated minimum 700mA power supply. The camera is
provided with a fly lead with a mini power 2.1mm DC socket. The camera is polarity sensitive so
connections must be correctly made.
Connecting the camera to control equipment
The dome camera comes with a fly lead for power, TVI/AHD/CVI/CVBS selected BNC video
output plus a second analogue (CVBS) video output on a separate BNC lead. Connect the HD
camera to control equipment via a female BNC-BNC lead. When using a co-ax type cable such as
RG59 or similar, the outer braid of the co-ax provides the “0V GROUND” connection and the inner
core provides the “Video” connection. The separate analogue (CVBS) output is primarily available
for setup purposes but can be used for viewing via an analogue monitor. Note that you cannot use
both analogue outputs together but can view one analogue and one HD.
switch cycle
When you are in correct format, press the joystick button in, momentarily, if you wish to access the
menu.
Manual Zoom and Focus
This camera has a 2.8 ~ 12mm vari-focal lens and is adjusted manually. There are two adjusters on
the lens and they are marked Zoom and Focus. Note that you need to first remove the black covers
with the flat metal key provided, by unscrewing anti-clockwise.
Note that turning the black
covers does not adjust the zoom and focus.
Underneath the black covers are the actual zoom and
focus controls. Adjust the Zoom first using the metal key provided, and when all areas of the picture
viewed are captured albeit out of focus, adjust the Focus to get sharpest picture. There is a digital
correction for sharpness in the camera menu. Only use this, when the best optical picture is acquired
first.
Improve Night time picture
Recommend
setting brightness to 75% and Sense-Up to x2 in Exposure menu and set Day&Night
to Auto rather than External. Note that this will not always provide best results but is worth trying
first.
These cameras can be viewed in TVI, AHD, CVI and CVBS.
First power the camera up when it is connected to a monitor or
DVR and monitor, and see if the required format displays a
colour picture. If not, press the joystick button in and not
down, for 3 seconds. Repeat until picture displays in colour and
is sharp. (Note that picture may be in b/w in low light levels or
the cellophane lens cover has not been removed).
Alternatively if you use the menu, you can change the camera
format in the menu:
Example - Change camera format to TVI:
<System> <Output> <MAIN OUTPUT ANALOG OUT0
