There
are security risks wherever there are more than two people gathered in a place.
These could be the lobby of a hotel, the parking lot of a high-rise building, a
mall, an office, casinos, markets, railway stations, bus terminals or even
hospitals. Not everyone who comes to such places does so because he or she has
a legitimate reason. Theft, pickpocket, vandalism, molestation and murder are
only some of the risks that you need to budget for if you are responsible for the
administration of any such place. A good preventive measure would be to install
a high range infrared CCTV to keep an eye on who are
coming and going and what they are doing.
The
advanced wireless CCTV cameras use the digital video recorders whereas the
analogue cameras use the still photos. The recorded images are saved on either
tapes or digital devices to maintain the database. They can be in a wide
variety of indoor and outdoor locations throughout the day. The advanced
systems contain built-in audio devices which permit the operators to be able to
communicate with people within range of the cameras. They can be used by the
traffic signals in the city to monitor the traffic flow and send out
information to GPS system as well as to assist in identifying traffic jams and
accident spots.
Passive
infrared technology or PIR instantly and accurately detects any change in the
room’s heat signature contributed by an occupant’s motion. Infrared technology
also makes day and night surveillance possible with these cameras as they can
operate under low-light conditions. It always makes sense to test every unit
you install. Look for the kind of CCTV
camera tester which can initiate video surveillance installation and
test, audio signal test; has a 3.5-inch TFT display screen with a resolution of
320 x 240 pixels. Ideally it should have low-power consumption with a working
time up to 8 hours.
