Installing the dome enclosure
1. Remove the dome cover
Use the supplied Torx driver to loosen (but not remove) the four cover screws.
The screws are captive and will be retained in the lid.
2. Use the template to mark and prepare the mounting area
The vandal resistant dome was designed to maintain their IP and NEMA ratings
independent of the install method chosen. Therefore, all mounting access positions
are sealed until they are ready to be used. For example, when surface-mounting the
housing, first knock out the screw access holes that correspond to the template marks
"T1". This can be done using a crosshead screwdriver.
3. Open the required knock-out panel
Carefully drill (or tap out) either the base knock-out (E1) or internal side knock-out
(E3) to the size required to allow cable entry. When surface mounting and using the
side knock-out (E3), open the cut out (E4) within the outer ring to the required size
by cutting away excess material with a hole cutter, sharp knife or side cutters.
4. Mount the dome enclosure
Using one of the mounting schemes discussed overleaf (methods for mounting the
enclosure), fix the dome enclosure (and outer ring, if necessary) in place. When flush
mounting or surface mounting using the outer ring,
ensure that the large rubber gasket (E6) is in place
under the lip of the dome enclosure.
IMPORTANT: If the dome is being mounted
externally using the four base holes, use the supplied
rubber o-rings within each of the four mounting holes
of the dome base to ensure moisture resistant seals
(see Fig. C overleaf).
5. Connect the wiring
Feed the preconnected main lead (that terminates in
connections F1 and F2) through the knock-out hole
and connect it to your video out and power in cables. A wire-ended adaptor lead (F8)
is supplied for use with power supply cables that are not terminated with an
appropriate power connector (For 12 VDC operation: Connect the red lead to +ve and
the black lead to -ve. For 24 VAC connection, polarity is not important).
IMPORTANT: The power supply must be Class 2 certified.
IMPORTANT: If the dome is being mounted externally, use a suitable sealant around
the cable access hole to ensure a moisture resistant seal.
6. Fit the camera assembly
Connect the camera to the fly-connector (F4). For ZC-DWT4039 series camera only:
also connect the OSD lead (F6) between the camera and the middle socket of the
smaller circuit board. Place the complete camera assembly (G1) onto the three
mounting pillars within the enclosure.
Note: Gimbal screws are supplied with both the housing and the camera assembly
(when supplied separately), therefore, you should have three screws left over.
7. Remove the camera liner
Lift the camera liner (H1) from the chassis (H2) to provide full access to the camera.
8. Adjust the camera position and test
Rotate and pan the camera chassis to the required position and then tighten the
camera chassis locking screws. Note: For specific camera adjustments (i.e. focusing
and settings), please see the Camera Sheet.
9. Replace the camera liner
Carefully fit the camera liner (J1) over the focused camera so that it is fully seated on
the top ring of the camera chassis (J2) and provides an unobstructed view for the
camera lens.
10. Replace the dome cover
Replace the dome cover (four small internal ribs within the cover locate within four
corresponding index slots (E6) within the enclosure body; these restrict the lid to only
four possible orientations and ensure that the cover screw holes are correctly aligned).
Use the supplied Torx bit to tighten the four cover screws
- DO NOT OVERTIGHTEN.
