Recommendation for Shielded network cables
STP cables have additional shielding material that is used to reduce external interference. The
shield also reduces the emission at any point in the path of the cable. Our recommendation is
to deploy an STP network cable in demanding electrical environments. Examples of
demanding indoor environments are where the network cable is located in parallel with
electrical mains supply cables or where large inductive loads such as motors or contactors are
in close vicinity to the camera or its cable. It is also mandatory to use an STP cable where the
power device (like IP camera) is used outdoors or where the network cable is routed outdoors.

commercial or industrial installation. This equipment generates, uses, and
can radiate radio frequency energy. It may cause harmful interference to
radio communications if the equipment is not installed and used in
accordance with the instructions.

FCC Warning
This Equipment has been tested and found to comply with the limits for a
Class-A digital device, pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy. It may cause harmful interference to radio
communications if the equipment is not installed and used in accordance
with the instructions. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
CE Mark Warning
This is a Class-A product. In a domestic environment this product may
cause radio interference in which case the user may be required to take
adequate measures.

2.3 IP Protection
The IP Code, Ingress Protection Rating, sometimes also interpreted as International
Protection Rating, classifies and rates the degree of protection provided against the
intrusion (including body parts such as hands and fingers), dust, accidental contact, and
water in mechanical casings and with electrical enclosures. It is published by the
International Electrotechnical Commission (IEC)
Solid particle protection
The first digit indicates the level of protection that the enclosure provides against access
to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid
foreign objects.
Level
Object size
protected against
Effective against
0
—
No protection against contact and ingress of objects

Dripping
water
Dripping water (vertically
falling drops) shall have no
harmful effect.
Test duration: 10 minutes
Water equivalent to 1 mm
rainfall per minute
2
Dripping
water when
tilted up to
15°
Vertically dripping water
shall have no harmful effect
when the enclosure is tilted
at an angle up to 15°from
its normal position.
Test duration: 10 minutes
Water equivalent to 3 mm
rainfall per minute
3
Spraying
water
Water falling as a spray at
any angle up to 60°from
the vertical shall have no
harmful effect.
Test duration: 5 minutes
Water volume: 0.7 litres per
minute
Pressure: 80–100 kPa

Immersion
up to 1 m
Ingress of water in harmful
quantity shall not be
possible when the
enclosure is immersed in
water under defined
conditions of pressure and
time (up to 1 m of
submersion).
Test duration: 30 minutes
Immersion at depth of at
least 1 m measured at
bottom of device, and at least
15 cm measured at top of
device
8
Immersion
beyond 1 m
The equipment is suitable
for continuous immersion in
water under conditions
which shall be specified by
the manufacturer.
Normally, this will mean
that the equipment is
hermetically sealed.
However, with certain types
of equipment, it can mean
that water can enter but
only in such a manner that
it produces no harmful
effects.
