Video loss
Video loss is inherent to digital video recording; therefore,
Bosch Security Systems cannot be held liable for any damage
that results from missing video information. To minimize the
risk of lost digital information, Bosch Security Systems recom-
mends multiple, redundant recording systems, and a procedure
to back up all analog and digital information.

tially damp environments, ensure to ground the system
using the ground connection of the power supply connec-
tor (see section: Connecting external power supply).

conductors, location of discharge unit, connection to
grounding electrodes, and requirements for the grounding
electrode.
– Permanently connected equipment - Incorporate a readily
accessible disconnect device in the building installation
wiring.
– PoE - Never supply power via the Ethernet connection
(PoE) when power is already supplied via the power con-
nector.
– Pole power switch - Incorporate an all-pole power switch,
with a contact separation of at least 3 mm in each pole,
into the electrical installation of the building.

power lines, power circuits, or electrical lights, nor where
it may contact such power lines, circuits, or lights.
