Installation Manual 3.0 Safety
3.2 Grounding
l
To provide protection against electrical surges induced by lightning, static charges, or any other
cause, the camera and cabling system must be properly grounded to earth. For installation on a
building, the camera must be bonded (that is, provided with a low impedance connection) to the
building’s structural earth ground system. For installation on a metal pole with a proper ground system
at the base, the camera must be bonded to the pole. For installation on a non-grounded or insulated
support, the camera must be grounded with an adequate ground strap or wire between the camera
and a nearby ground sys-tem, or to a ground system installed at the base of the support. Failure to
adequately ground the cam-era may lead to failure of the camera. This applies to low voltage (24 V
AC
and PoE cameras) as well as to 120 V
AC
cameras.
l
Failures due to surges are not covered by the warranty, as they are not due to defects in
material or workmanship, and it is the installer’s responsibility to meet these grounding
requirements.
Note: Refer to
" Best Practices" on page 17
Surge Protection Devices for additional information on
grounding and surge protection concepts.
