cameras and facial recognition are used to monitor public and private
spaces and to identify people. The effectiveness of this technology is
up for debate, but it is nevertheless becoming both more pervasive and
Surveillance cameras (also known as Closed-Circuit Television or
CCTV) are increasingly being used to monitor public and private spaces
throughout the world. Governments and law enforcement authorities have
used video surveillance in various circumstances ranging from the
investigation of crimes, the protection of urban environments and
government buildings, traffic control, the monitoring of demonstrators
and in the context of criminal investigations.
Proponents contend that video surveillance is both a deterrent to
criminals and an aid to solving crime. Camera systems are usually rolled
out with little prior research into the effectiveness or
appropriateness of the technology, in many cases simple because the
impression of heightened security is good PR for local government.
Studies of the efficacy of CCTV in preventing crime have been
inconclusive at best.
Facial recognition systems use computerized pattern-matching
technology to automatically identify peoples’ faces. While still very
much in its infancy, it raises significant public policy questions
because it enables the covert identification and classification of
people in public.
As security camera technologies continue to evolve, there are
new solutions for those who previously were not able to utilize
hardwired systems. Wireless security cameras are very advantageous for
those that need to go without wires for easier placement. One reason
customers choose wireless IP security cameras over other types of
technology is due to the camera system’s flexibility. Before delving
into more about wireless technology, it’s important to refute some of
the common misconceptions that people have about these types of
Battery Operated Wireless Security Cameras
Wireless cameras still need power source to function. The
belief that wireless security cameras are battery-operated is a common
misconception: No real security cameras use battery power. The only
battery-operated cameras that are available on the market are not
suitable for protecting your home or business, and can’t be integrated
into an existing video surveillance system. Listed below are two
primary modes of powering wireless cameras:
You can choose to power your wireless camera with a
wall plug adaptor, but be forewarned: it’s not secure and it isn’t a
good look for the home or office. The black and cumbersome power cords
that plug into the wall are not a pretty sight, and can be potentially
dangerous to children or adults who can trip on them.
Power-over-Ethernet (PoE) technology is often the
best choice for powering your camera system, removing the need for
wireless. First and foremost, it’s secure and doesn’t require the
additional cabling needed to plug the camera into a wall plug adaptor.
Moreover, PoE extenders can provide an effective distance of up to 900
feet, enabling you to place cameras in far-away location without losing
