FIRST ALERT SIGN
Tip:
Decoy Cameras act as a gr
eat
deterrent if you don’t have
real cameras or they can make
your live system seem to be
more extensive.
The IP rating is used to specify the strength of the enclosure that surrounds electronic equipment
and is determined by specific tests. Each IP rating consists of using two separate measures. The
first is protection against solids; the second number is protection against liquids. So therefore an
IP rating of 65 is totally protected against dust and is protected against low pressure jets of water
from all directions with limited ingress permitted.
