Surveillance System Buying AdviceA good surveillance system is a key component
to any home security system. Surveillance generally means to
ˇ°surveyˇ± the surrounding so that you know what is around you
and what should not be around you. Surveillance systems can
include many different security devices all working together.
These can be security cameras, video recorders, motion
sensors, etc. Additionally, a central computer that can
analyze the data from various surveillance devices is also
helpful. In thinking about the importance of a good
surveillance system, consider the following: |

The violent crime rate has remained barely unchanged through
out the whole American continent in recent years. However, the
statistics show that nearly all categories of crimes against
property rose last year, including burglaries, vehicular thefts,
possession of stolen goods and minor thefts. It's the first
substantial increase in property crimes in over a decade. Important
increases were also noticed for common minor offences, such as
mischief, shoplifting and disturbing the peace.
On the other
hand, authorities noticed a considerable decline in the shoplifting
rate in stores that have installed surveillance systems. The newly
developed digital recording systems gives you a clearer image better
than the former video recording systems that uses cassettes. This
means that it's easier to visually identify an offensive individual.
You are in the office and worried about home, could there be
someone who sneaked into your room and move away your properties?
Surveillance system now would be your total solution. The
surveillance program running on your home PC attached with the
webcam will monitor any motion detected. It will call your mobile
phone or office phone or email you when a motion is detected. Upon
receiving such a call, you can immediately launch your Internet
explorer to check out images captured by your webcam at home. You
can also launch your Remote View software in your office and connect
to surveillance system to check out what's going on at your home by
watching real-time video. Even if you cannot use the Remote View
software at that time, the surveillance system will record the event
into video clips for you to view later.
Hard-wired
surveillance systems use wires installed inside the walls, attics,
crawl spaces, and underground to connect the sensors to a central
controller. Surveillance cameras or microphones are also wired to
speakers, video switchers, and video display monitors. A hard-wired
system design normally uses power from the home AC power wiring as
the primary source. Rechargeable battery pack is used for the
controller as power backup during power outages. The main components
of a hard-wired system are similar to a wireless system but without
the radio receiver and transmitter components. They include a
central control panel, sensors, one or more keypads, motion
detectors, smoke and fire sensors, cameras, camera switchers, video
displays, and sirens. The advantages for a hard-wired security
system are: first, hard-wired security systems are considered by
most contractors to be more reliable than wireless systems.
Secondly, professional security system technicians with warranties
and maintenance support will help you to install your system and
make sure you will have nothing to worry about. Third, hard-wired
systems avoid the problem of EMI and radio range limitations
inherent in some wireless security systems. Forth, hard-wired
systems do not depend on batteries except for power failure backup
protection.
Buying Tips:
Make sure that the
company that is selling or providing consultancy of security
surveillance systems has certified security and video surveillance
experts who are able to assess your particular home security needs.
Because every customer has different home security needs, it is
important that the surveillance system is tailored to fit your home
specifically.
