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.
