POWER QUALITY
As
with
any
IT
equipment,
Endura
components
rely
on
proper
installation
practices
to
minimize
power
surges
and
other
fluctuations
with
the
power
supply.
Unlike
IT
equipment,
Endura
components
use
custom
designed
power
supplies
that
meet
EN50130
‐
4
standard
for
alarm
monitoring
equipment.
This
allows
the
component
to
withstand
a
five
‐
cycle
dip
in
power
supply
without
resetting.
Even
with
these
precautions
incorporated
into
the
design,
power
fluctuations
can
still
adversely
affect
the
equipment
and
should
be
avoided.
Power
quality
can
be
measured
using
a
power
quality
analyzer.
The
following
list
describes
the
common
issues
that
must
be
mitigated
to
protect
your
system
and
equipment.
The
equipment
problems
associated
with
these
anomalies
range
from
video
distortion
and
un
‐
intended
increases
in
bit
‐
rates
to
damaged
electronic
components.
•
Frequency:
Variation
of
the
power
waveform
•
Harmonic
distortion:
Multiples
of
power
frequency
superimposed
on
the
power
waveform
•
Line
noise:
Distortions
superimposed
on
the
power
waveform
•
Overvoltage:
Increased
voltages
for
an
extended
period
of
time
•
Power
failure:
Total
loss
of
utility
power
•
Power
sag:
Short
term
under
‐
voltage
•
Power
surge
(spike):
Quick
burst
of
overvoltage
•
Switching
transient:
Under
‐
voltage
or
overvoltage
for
up
to
a
few
nanoseconds
•
Under
‐
voltage
(brownout):
Low
line
voltages
for
an
extended
period
of
time
NOTE:
If
these
issues
are
suspected
or
known
to
occur
for
a
given
site,
ensure
that
proper
steps
have
been
taken
to
isolate
the
equipment
from
these
anomalies
prior
to
turning
on
the
Endura
equipment.
RECOMMENDED
PROTECTION
PRACTICES
The
Endura
system
can
be
protected
from
many
sources
of
electrical
disturbances
by
adhering
to
the
following
the
recommendations.
Please
note
that
it
is
beyond
the
scope
of
this
document
to
provide
explicit
instructions
for
electrical
distribution
system
design
and
configuration.
If
in
doubt,
please
consult
with
a
licensed
electrical
contractor.
•
Dedicate
a
power
distribution
system
for
the
video
surveillance
equipment
•
Minimize
the
use
of
high
‐
current
draw
devices
such
as
heating,
ventilation,
and
air
conditioning
(HVAC)
units
placed
on
the
Endura
power
distribution
network,
as
these
can
cause
a
dip
or
interruption
when
the
equipment
turns
on
•
Do
not
connect
the
Endura
system
to
circuits
with
inductive
loads
(for
example
HVAC,
motors,
and
so
forth)
•
Where
possible,
use
power
conditioning
equipment
(line
conditioner)
that
smoothes
out
peaks
and
dips
on
the
power
network
•
Where
possible,
use
over
‐
and
under
‐
voltage
detection
and
protection
circuits
•
Install
lightning
arresters
(surge
protectors/suppressors)
on
power
cords
to
protect
equipment
against
electrical
storms
•
Use
UPS
systems
and,
as
appropriate,
a
backup
generator
