QUICK Installation Guide
4 mm Wide-Angle Lense for IN-5907HD
Content of delivery: 1x Wide-angle lense; 4x screws; 4x spacer; 4x springs; 3x diuser lenses; 1x installation guide
Step 9-1: Now to the complicated
part: Take a spring from this Upgrade
Pack and place it between the LED
board and a short spacer. Use the in-
cluded long screws to lock this con-
struction in place by fastening the
screw onto the short spacer. Repeat
this for the remaining three spacers
(Fig. 10, 11 & 12).
For now it is only required to fasten
the screws by two turns.
Important! Please make sure the
LED board and the sensor board are
aligned correctly! (Fig.12)
Step 7: Please take the new wide-angle lense
and mount it in the lense mount by turning it
clockwise. Screw it all the way in and fasten the
xing screw on the lense mount in order to se-
cure the lense (Fig. 9).
Step 9-2: The sensor board has a cut-out
on the right side. The LEDs on the LED
board are on top while the brightness
sensor is at the bottom (Fig.12)
Step 11: You now may reapply the black front sheet cover to the LED board. But please
make sure you won’t need any further readjustment of your lense rst. This package
includes special diusing reectors for the extended viewing angle. Simply plug them
on top of the infrared LEDs like the original reectors from Fig. 2 used to be.
Step 10: Now put the whole front part back
into the camera casing and secure it with the
three outer screws removed before in Step 3
(Fig. 4). You will now need to move the lense
closer to the glass cover. In order to do that,
you need to fasten the four screws on the
LED board by one turn (Fig. 13). Dont turn
them too far since that would cause the lense
to come to much frontward which will give-
pressure to the front glass and you will risk
damaging the front glass of your camera per-
manently.
camera to your network and open the camera’s web interface in your web browser. While
keeping an eye on the cameras live video, slowly turn the front part of the lense to the left
or to the right until you get a sharp and clear image. Once done please fasten the xing
screw to keep this setting.
Notice: The outer ring is the part of the lens with the specication printing.
Important: In case you see reections
when it is dark and the IR LEDs are ac-
tivated, you can x that by sliding the
top cover more to the back. You can
also use the original reectors to limit
the illumination angle.
Step 8: After the installation you will need to
adjust the focal point of the lense. To do so you
need to untighten the xing screw on the out-
er ring of the lense (Fig. 9). Now connect the
Step 12: At last, carefully screw the
front cover back on the casing by turn-
ing it clockwise. Make sure to screw it
on tightly but without breaking the
front glass. In case the wide-angle
lense sticks out too much, you will
have to refer to step 10. Slide the top
cover back into position (see Fig. 1)
and enjoy your new wide-angle lense.
