IP camera VS analog cctv camera, which
system is the best?
When users consider the video surveillance system, they don't know how to choose
between IP camera system and analog cctv system. Today, we are going to discuss this
with you. To answer this question, the short answer is IP camera system is better than
analog cctv system. Since the IP camera system becomes more and more affordable,
and if you are going to setup a new surveillance system, the IP camera system is the
ideal or best choice.
For many years right now the popularity of IP based video camera systems have been
growing due to the reducing of the cost of network bandwidth. They have also become
popular as a result of enhancements in compression technologies (most notably the
developments in H. 264 and H.265) which have led to network bandwidth usage
becoming more control-able, coinciding with wider adoption of high speed broadband
and now fiber-based ‘super-fast’ broadband in lots of nations on the globe.
A lot of businesses that need versatile, cost-effective surveillance solutions, are now
preferring IP video cameras more than analog video cameras due to the more advanced
functions of IP cameras, such as remote control availability, much better scalability,
ever growing processing power, constantly improving video analytic, on-board storage
capacity and also imaging technologies.
Within CCTV (closed circuit television), the surveillance images are first captured and
are then relayed as an uncompressed analog video signal through coaxial cable towards
the DVR (digital video recorder) where they are recorded.
In IP structured camera systems the images are captured by the IP cameras and are
converted to a digital signal which is then compressed and stored on the PC storage
devices such as a hard drive or flash drive, by using wired setup (CAT 5 network cables)
or a wireless network, and as a result they help businesses save on the cost of set up
since their existing network infrastructure can be re-purposed for surveillance.
Comparison between CCTV camera and
IP camera
Analog CCTV camera with or without DVR
Easy to operate and setup, no network configuration
Poor and standard image resolution
Image quality will decrease after video recording
Analog signal, prone to be interfered.
Difficult to expand the system
Cable infrastructure is required for new system
Less expensive on camera, but overall cost is high
IP-Camera surveillance system
Latest digital technology, current trend
Plug-and-play setup
High definition images reach up to 6 megapixel
No quality loss after video recording
Broadcasting video stream over internet, accessible from anywhere
Working standalone, no need recording devices (NVR, NVS)
Using existing Cat 5 Ethernet infrastructure for connection
Expensive cost for IP camera, overall cost is low
Easy to expand, and many advanced functions
The Reason Why IP Cameras Are Much
better than Analog CCTV Cameras
1. Image quality - The high resolution graphics recorded on IP cameras provide crystal
clear images. The more clear the image, the easier it is to discern people, objects, faces
and other details filmed through the IP camera.In IP based digital camera systems there
isn't any loss of quality in recording of images or reviewing recordings, since all of the
data is recorded digitally instead of getting converted from analog to digital. In analog
CCTV systems, there’s a decline in the image quality the further the data has to travel.
2. Resolution - A typical analog camera equates to about 0. 4 megapixels, while a
standard IP digital camera provides two megapixels, that is more than 5 times the
resolution provided by analog video cameras. As a result of the larger resolution
provided by IP digital cameras, IP-based digital camera systems demand fewer
cameras as compared to analog CCTV systems.
3. System based on needs -Because IP cameras don’t require additional cables like
analog video cameras do, the network can be as huge or as small as required. The
network can be easily expanded and other systems can be added or integrated to it at
any time without being compelled to drastically change its infrastructure. For example,
in property as well as building management the IP digital cameras might be integrated
with the security and alert systems and in a retail business they may be integrated with
the point of sale system.
4. Versatility - In IP based camera systems the bandwidth could be controlled
differently for every IP camera. For the recording of video clip the hard disk drive space
could be shared by many systems. Any number of recordings per IP camera can also be
done at the same time, from various locations for redundancy purposes, offsite storage
or even live video surveillance at the service providers.
5. Unlimited Scalability - IP based camera systems can start out small and then grow
over time as the needs of the business or house increase. There’s no limit to the amount
of IP cameras and also sites that may be included in the system. The capability to run
on network sections and also multiple networks and distributed processing serve to
reduce the limitations on scalability.
In an analog CCTV system, a dedicated coaxial cable needs to be directly connected to
each video camera and the recording /viewing station. This means that changing the
infrastructure of the system and also including more video cameras might be too
complicated, costly, and also eventually limit the unique security needs of your
enterprise or home.
6. Video management - All of the data generated in IP based digital camera systems is
recorded in a digital format, and as a result it’s easily accessible for playback. Every real
time or recorded data can be quickly reviewed from any location. In a place exactly
where the quantity of data being produced is actually too much to review, a smart
system along with analytic software can be utilized.
The intelligent system can be established in order to respond to pre-programmed
commands such as event management, motion detection, sound detection and
tampering alarms. All of the data can then be recorded and sorted in a way that is
helpful to the end user, which includes by event type, camera, area or date.
7. Economical - IP based camera systems offer a more affordable solution due to them
requiring small infrastructure for installation and use. The majority of corporations and
households have already some kind of network available upon which they can set up the
IP cameras.
Regardless of the size of your network you can purchase the number of IP digital
cameras which are required or that match your budget. The purchase monitors may not
be necessary if setting up an IP based digital camera system because the images will be
displayed over the web from any kind of laptop or computer.
IP based camera systems offer you amazing functions and also features which can't be
matched by any analog CCTV system. The adoption of IP based camera systems in
some countries has been slow due to the legacy of analog CCTV systems.
Over the past few decades millions of analog CCTV systems were installed around the
globe. An industry grew to install and maintain these types of CCTV systems,
consequently there's been a reluctance to write off the large expense in analog CCTV
systems.Nevertheless, due to the incredible benefits offered by IP digital cameras, IP
based camera systems will certainly take over analog CCTV systems worldwide in the
future.
