The principle of operation of all kinds of CCTV cameras - comes down to what is basically a video eyes, they determine that the visual information that is ultimately delivered to the operator. However, unlike the eye, the use of video cameras provides the operator with a unique ability to see the screen monitor Image of the many rather remote locations.
The basis of modern cameras is the so-called CCD (CCD - Charge Coupled Device) - a rectangular plate with a light-sensitive semiconductor ratio of 3: 4.
| | Video Surveillance
90% of information that takes a person goes through his eyes, so the surveillance system and got the expansion. In the videoonablyudeniya
in recent years are a huge change, developing new scientific methods of video analytics
Improves the quality and speed of video.
CCTV , a digital system,
is a software and hardware system, designed to
organization of systems technology and CCTV. Allows
organize video surveillance in both local and on the
geographically distributed sites.
security surveillance system is
an electronic device - capture card (ottsifrovki) video signal to a computer and installed the standard PC. Video surveillance
is based on one important point - digitization and hardware
compression of analog video camera signal into a digital code, which is then processed by software.
Today digital video surveillance is
a number of functional features that make it stand out favorably against the
analog systems, which are increasingly becoming obsolete. Safe installation of CCTV cameras in the apartment even with the record, make this technology even more accessible.
A video surveillance system based on a modular principle, which allows it to easily build up, thus providing connectivity
more cameras. Because of this, video surveillance can
to operate an unlimited number of cameras, it is very important for global
CCTV systems are located in large enterprises. Another
feature of digital video surveillance system is its
surveillance devices allow you to record video
with an unlimited number of cameras at up to 25 frames per second
resolution of 704 x 576 pixels. In addition, video surveillance provides
high-speed access to stored videos and good quality
playing video. Software systems allows
combined into a single network distributed local surveillance systems
for further centralized administration and control -
surveillance system operator can be simultaneously displayed on the monitor image from any of the cameras that are connected to
| | Access Control
System access control -
sistemamy multifaceted electronic security. Normal door is installed into a mechanical or electromechanical locking turnstile with
janitor system and are also defined as access control .
First electronic systems are designed to provide
access certain people in certain areas (you can control
their movements) and restrict the access of persons who do not have access rights
in the appropriate room. That is access control - this electronic system, allowing to solve problems of any complexity.
But more complex systems consist of one or more computers, access control can control the situation based on the current time,
day of the week and holidays. System
can make a log of all events: user passes through a door at a certain time, attempts
unauthorized access, etc. Software access control allows
receive different types of reports on events that took place in the system for
time. Also, different systems access control can be large
additional functions, such as protection against unauthorized
entry to the premises by sending an Access Card (TM Key - access control entry)
another person, a graphical representation of a computer monitor with a plan of the protected object
display of alarm conditions, etc.
Direct function access control - access control, but the system can also be used to account
working time, control of the route
security guard, control of various devices (lights, sirens and
etc.) focusing on the events that occur in the system. Many systems access control
have the ability to connect sensors and alarm
generate an alarm or control the CCTV system
. Consider an example - if you try to enter the premises for illegal users
(Presentation of the system of illegal access cards) access control enable recording
with cameras and record the actions of the offender.
| | Video
DVR allows you to record video to the hard drive and look for the right parts at a faster rate
better resolution and to a greater extent through the use of modern computer technology. The device hardware
can be performed as a PC-compatible card that is inserted in the PCI-slot in the computer, or as a separate device (called
non-PC or Stand Alone DVRs).
Any digital video recorder has a special slot for the hard drive, which is recorded and
video, some models have the ability to connect a second drive for backup. The resulting
so the image can be viewed repeatedly without deterioration, can be stored indefinitely
and requires no maintenance vehicles. Most models have alarm inputs, allowing you to enable recording
in the case where a signal appears on these inputs or record footage at a higher resolution when triggered alarm
sensors. This allows optimal use of capacity of the hard disk and store it large amounts of information.
use of digital video recorders has several advantages over the use of multiplexers and VCRs. First of all, write to the hard disk has
higher quality, much longer life, it is more convenient to store and archive and search all your information is faster and more convenient.
