Installation

Use the supplied large torx driver to loosen the four cover 
screws.  The screws are captive and will remain in the 
cover (image A).

Loosen the gimbal securing screws to remove the camera 
module (image B).

Cut a 4.3” (110mm) hole in the mounting surface as indicated by the template marking T3.  Insert the dome 
base and turn the silver-colored screws counter-clockwise by 180° to extend the locking arms and tighten 
them against the mounting surface (image I). 

Cut a 1.5” (38mm) hole in the mounting surface using the T2 marking on the template.  Insert the adapter 
and turn the screws counter-clockwise one turn to extend the arms, then turn the screws clockwise to pull 
the arms toward the flange and secure the adapter to the mounting surface (image J).

Push the cables through the opening and the 1/2” rubber grommet.  Make sure the grommet is properly 
installed on the adapter to prevent dust penetration (image K).

Note:

 To protect against dust and moisture penetration, always use the large rubber gasket on the dome 

base when installing.

IMPORTANT:

  If the dome is mounted externally using screws, use the suppled rubber o-rings over each of 

the four mounting holes of the dome base to ensure a moisture resistant seal.  Tighten the screws sufficiently 
to compress the o-ring moisture seals located underneath the screwheads.  

Do not overtighten

.

IMPORTANT:

  If the dome is mounted externally, use a suitable sealant aroung the cable entry hole to 

ensure a moisture resistant seal.  This prevents water vapour, from the connected conduit, from condensing 
inside the housing.

Tighten the gimbal screws with a screw driver to re-install the camera module.

Adjust the camera position by rotating and panning the camera base.  The focus and range of the lens 
can also be adjusted

Carefully fit the camera liner over the camera base so that it snaps into place 
(image F).  Do not obstruct the camera lens.

Replace the dome cover using the index mars (image G) 
to align it.  Tighten the torx screws to secure the cover.  Do 
not overtighten.

Feed the pre-connected main lead through one of the 
cable access points and connect it to your video output and 
power input cables.  A wire-ended adaptor lead (E1) is 
suppled for use with power supply cables that are not 
terminated with the appropriate power connector.

For 12VDC operation: Connect the red lead to positive and 
the black lead to negative.

Use either the base cable entry (C1) for the side cable 
entry (C2) as required.  When surface mounting and using 
the side cable entry (C2), open the large (C3) or small (C4) 
knock-out on the outer ring to required size by cutting 
away excess material.  Rotate the outer ring so that the 
knock-out aligns with the side cable entry.  Seal an unused 
side cable entry with a sealing plug (C5).  Use the supplied 
rubber grommet (C6) to prevent dust penetration when 
using the base cable entry.  For external applications, 
conduit should be used to carry cables into the housing.

Mount the camera base, using screws, on a US single 
gang box, using the flush mount locking arms, or using the 
quick install adaptor.  See the individual instructions below 
and at right.

When mounting the dome to a ceiling or wall using screws, knock out the four screw access holes on the 
base that correspond to the template marks 

T1

 using a phillips head screw driver (image D).  Drill four 

holes in the mounting surface using template marks 

T1

 and cut a hole using template marking 

T4

 for the 

3/4” base cable entry.

When flush mounting or surface mounting using the outer ring, ensure that the large rubber gasket
(image I) is in place under the lip of the dome enclosure.

When mounting the dome to a single gang box, 
carefully remove the screws from the securing 
position on the box.  Insert the 3/4” rubber 
grommet in the base cable entry to prevent dust 
penetration and push the cables through the dome 
base and grommet.

Mount the dome base using the two screws 
removed earlier.  Tighten the screws sufficiently to 
secure the base to the box (position
