decide whether you want a camera with NVR or DVR system. Although both IP and
analog systems are used for security purposes, they have different features and
functionalities. From installation to usability both cameras have very
diversified. In this article, I would discuss the main features of DVR and NVR,
why they are different and what are the major pros and cons of using these
security cameras.
The information provided
in this article would help you to buy the right CCTV cameras depending on different
security components. The CCTV cost for home in Lahore for both DVR and
NVR are different, typically, DVR cameras are a little bit expensive because
they are hardwired and you need for cables and extra equipment to mount them.
You may not need professional help to buy CCTV cameras because this guide would
help you to make the right decision about buying perfect CCTV cameras.
About DVR
Digital video recorders use
with analog systems but they have many advanced functionalities than the
traditional analog security systems. Unlike traditional analog system, it makes
video recording using the hard disk. This system has the ability to store and
process images, and you can also perform other functions such as controlling
images, remote monitoring and recording. There are many added features in the
DVR that are not available in typical analog systems that make them a better
option for maintaining security.
About NVR
IP CCTV systems use NVR technology
to record video footage. For storing, recording or forwarding the video
footages, NVR uses video encoders. The smart features of NVR security systems
fulfil the needs of advanced CCTV cameras in Lahore. One of the best
things about NVR security systems is that they are easy to use, cost-effective
and flexible. These are high-resolution security systems that can allow 720P video
access. These cameras come with a lot of conveniences, for example, you can
control, manage and view the video of these cameras remotely and most these
cameras also provide a two-way audio recording. The DVR systems are highly
flexible and easy to control, you also don’t need to have professional skills
to install these cameras. You can use these CCTV cameras at home, offices and
other commercial places.
DVR System’s Working,
Features and Usability
They are Analog
The DVR systems work with
analog cameras, most of the DVR cameras are hardwired that makes them less
flexible to install and move. The DVR cameras used analog signals for the
recording of CCTV footage. The one benefit of using DVR cameras is that they
are less complex compared with NVR security systems. You can get assistance
from online companies offering cheap CCTV camera installation in Lahore.
Video Footage Recorder
DVR uses the AD encoder
to process the video data and create a video recording that you can watch on
your monitor. In the DVR systems, all cameras are connected wit the recorder,
no matter what are the security requirements. The recorder is not responsible for
fulfils the power needs of cameras, in the DVR systems. To function properly,
splitter is connected to all cameras to fulfils the power needs.
Cables and Wires
Here comes the most
frustrating part of CCTV installations. I am pretty sure that no one wants to
bother about wires.
Not very surprising, as
it is mentioned above that DVR systems are usually hardwired and they coaxial
wires for installing their cameras. The video signals in these cameras are sent
through coaxial wires, below are some explanations of how coaxial wires work.
1.
In your DVR
system, two wires are used, one for video signals transmission and others to
get power. Because your DVR systems are depending on the cables, so you have to
install it close to your main power socket.
2.
You can upgrade
your security system using the same coaxial cables that you have utilized
previously.
3.
Undoubtedly, the
installation of DVR cameras is more difficult compared with the NVR cameras
because you have to arrange all the cables and wires during installations. You
can also get expert help to properly install your camera systems. If any of the
cables wrongly installed, it can cause your system to have operational issues.
4.
Although you can
get good video recording by using coaxial cables, you may not allow recording
audios, for audios you will require an RCA connection.
5.
The quality of
images with coaxial cable is good enough to improve your overall security. In
case of DVR, try to use good quality cables to avoid any signal loss.
Video Footage Quality
One thing you must know
before purchasing the DVR cameras is that they use analog signal through
coaxial wires and the processing of images are done while recording. It is
obvious that the image quality of DVR analog signals is not as good as the NVR
Wi-Fi signals. Not just that, with DVR cameras you cannot record the audios
along with your video footage.
Flexibility of System
When it comes to
flexibility, DVR cameras have some limitations. DVR systems are hard-wired and
you can not simply replace or move them. As compared with the NVR cameras
(which can be wireless or hardwired), DVR must need wires to operate. DVR systems are also hard to mount because a
lot of time and efforts are required to mount them correctly. The CCTV installation price in Lahore is higher than the NVR systems.
NVR System’s Working,
Features and Usability
Type of Camera
IP cameras use NVR
systems to process the video data transmit over Wi-fi network instead of the recorder,
the design of these cameras is minimalistic that make them less visible. The
best thing about NVR cameras is that you can watch the video recording through
your mobile at remote locations. In the case of IP cameras, the video data is
first processed and then transmit it to the recorder.
You can ensure more
security with NVR cameras because they not just record videos but you can also
get the audios. Do you know what’s the best part is? You will get good quality
images then DVR and it is very important to gather solid evidence against any
misconduct. Because NVR uses advanced technology that makes them more powerful
and effective to maintain technology.
Recorder
The rule of the NVR
system recorders is very different from DVR systems. The main difference is
that the recorders of NVR systems are not responsible for video signal
processing. The cameras itself do the video data processing and you can store
and views data through recorders.
Cabling
Say bye-bye to drilling
holes on wall for the arrangement of wires. Luckily, the NVR systems are known
for their no wire needs. it is true because most NVR systems are wire-free and
some may use wire just to plug into a power socket. Although both NVR and DVR
systems have to attach with the record, how they do it is completely different.
Yes, there is no need for excessive cabling but you may need one or two cables.
The expert technicians suggest using ethernet cables because they are more
beneficial than coaxial wires. In DVR systems, you have to contact any CCTV camera cheap installation service providers to place cameras for you.
Following are some of the
major advantages of ethernet cables.
1.
No need for
splitters, just use one Ethernet cable that is enough to transmit video, audio
data. Ethernet cable cables are hassle-free as compared with the coaxial
cables.
2.
Allows better
video data remission without losing the quality of the image.
3.
No one wants to
create a mess in their homes, Ethernet cables are preferred because of their
minimalistic design and small connectors.
4.
Ethernet cable is
not just more powerful and easy to manage but you can also get it at fewer
prices than coaxial cables. For home and small businesses security, you can go
for Ethernet.
5.
The best part is,
you can do it yourself, means no need for professional installations.
6.
Only one Ethernet
cable would be enough for all cameras, no need to attach a cable with every
camera separately.
Image /Audio Quality
Image quality matters,
especially if you want to gather evidence against offenders if any illegal
activity happened. NVR wins the game when it comes to image quality because in
Wi-Fi transmission don’t lose any signals. NVR systems use Ethernet cables that
are a plus for IP CCTV cameras.
More Flexibility
People ask me, why I
choose NVR IP cameras? My answer is: They are more flexible.
Flexibility can be a good
reason to buy a camera. NVR IP cameras are way too flexible than the DVR
cameras because you can easily move or upgrade them. Most of the NVR systems
don’t even need to be attached with the recorder. No matter where are your
security cameras are placed, even if they are at remote locations, they should
be connected to the same network.
