Do you know what the
latest development in wireless
security cameras is?
The latest revolution
in security cameras doesn't
involve the sensor or the lens, it involve the transmission signal.
Wireless security cameras are
now going WiFi.
Looking at the latest
technologies, it is no surprise that WiFi is welcomed in to this field. Many wireless surveillance cameras
are now available to make any surveillance system highly efficient and
functional.
A wifi security camera can
perform many functions such as remote viewing, motion detection and recording,
and the best of all is that it is battery operated.
To understand why
wireless surveillance cameras have become so popular, you must first understand
what WiFi stands for and its functions.

WiFi is short for wireless
fidelity refers to a set of wireless networking technologies and more
specifically referred to as any type of 802.11 network, 802.11b and 802.11a and
dual band. The word WiFi was built by an organization named as WiFi alliance. A
product that undergoes the WiFi alliance analyses is given the name WiFi
certified.
WiFi is a wireless
technology that handles the networking/communication between devices. WiFi is
caused by Radio waves that are transmitted from an antenna and WiFi receivers
pick them up. These signals are then broadcasted to the device with WiFi
connection.
WiFi equipped consumer
electronics range from automobiles, cameras, computers, camcorders, mobile
phones, video games, GPS systems, DVD players, printers, and many more.
Security cameras now have joined the growing list of WiFi devices. The reason
is attributed to many homes now having WLAN (WiFi local area network). You
would just have to connect the wireless
security camera to the network to give coverage of wider areas.
In WiFi surveillance cameras, the
video signals go over a wireless LAN and then to a video server or PC. You can
install a WiFi surveillance camera much faster than a traditional wired
security camera. Perhaps the biggest advantage is that the WiFi security camera can be
remotely controlled by laptop or phone with Internet facility and the picture
quality is uninterrupted. But the disadvantage lies in the security of the
video transfer. If it is not encrypted, it can easily be tapped and create
security problems.
How are WiFi surveillance cameras
better than regular wireless RF security cameras?
RF wireless
surveillance cameras use radio frequency wireless technology similar to some
high-end cordless phones to transmit and receive wireless video signals. It has
many advantages such as being mobile and can be set up anywhere. A major
drawback of wireless RF security camera is that the radio signals used to
transmit video can be interrupted by electric motored products such as AC,
fluorescent lighting or cordless telephones which affect the picture quality.
Where should you use a
WiFi surveillance camera?
A WiFi surveillance
camera is made for indoor use, whether for a company or home use. It must be
placed at locations with minimum RF interference.
What do resellers need
to be wary of when listing WiFi
surveillance cameras? As a seller of WiFi surveillance cameras, you must
list the compatibility properties of these cameras with the different types of
networks like 802.11b or 802.11g WiFi networks. This helps the customer make an
informed decision and avoid unnecessary problems of refunds and returns. You
become a trustworthy seller as opposed some sellers, who claim that the
surveillance cameras are WiFi enabled but they use radio waves for wireless
transmission and create network issues for the customer.
