5.01 Hardware Installation
The different parts of your camera are labelled here:
Once youʼve established a suitable fixing position, use the fixing
plate as a template to mark off the three Surface Fixing
Positions and the cable clearance position.
The camera is supplied with 3 x Stainless Steel, anti-tamper, self
tapping screws. Drill pilot holes accordingly and use a 14mm
hole saw to create the cable entry hole.
Attach the camera to itʼs base plate using the M5 x 10mm
Countersunk screws supplied. Iris recommend that a screw
fixing agent is used to strengthen the fit (see diagram below).
When the cables are correctly terminated (see next section),
offer the camera up into the fixing position and firmly screw into
place.
Observe extreme caution when siting the camera. Ensure the
act of drilling the pilot holes and cable entry hole does not
infringe any cables, equipment or fixtures behind the panel onto
which the camera is to be installed.
To avoid moisture ingress between the bottom of the BRK-P160
fixing plate and the surface onto which the camera is to be
attached, apply a bead of suitable silicone sealant around the
edge of the plate to create a seal.
