Advantages of an IP Security Camera CCTV System
In a Standard IP camera system, the key differentiation here is that the camera by itself is able to stream High definition HD digital video directly to a PoE Network Video Recorder (NVR).
Because the video format used is digital, there is no requirement for an analog to digital megapixel signal conversion.
As the Surveillance IP camera is an online device, the cabling requirement is usually only a single standard computer Ethernet Network wire. Such a digital IP network port audio connection enables a convenient two-way communication between users on the mobile phone network and the cameras.
1. Superior Video Resolution
One of the key reason why PoE IP camera systems have enjoyed such wide popularity is that the cameras can capture, record and deliver video in much higher definition & resolution quality in both day & night surveillance compared to an Analog to Digital Surveillance systems
2. Leverage on Existing Networking infrastructure
Other cost benefits of using a multi channel IP video CCTV is that is can utilize existing data network service infrastructure.
It is interesting to note is that in both an Analog & IP CCTV systems, the topology of both surveillance system cables are essentially similar whereby both the DVR and NVR is where the central video surveillance software logic package is installed.
This means that the DVR & NVR is the nucleus of the whole surveillance system. It is where all the system logic which performs important video management functions is located.
3. Direct Accessible & Searchable Videos
Using a normal internet browser, such as Internet Explorer or a viewing client, end users connected to the PoE network can efficiently send video sequence search based on camera location event type, time and date, regardless of whether the video is stored and play directly from the storage media itself.
Note that network bandwidth on the common PoE sign network is used only when a user query on a specific stored video is requested
Disadvantages of Analog CCTV System
In a typical CCTV surveillance system, analog video is electronically streamed directly from the CCTV cameras to a centralized Digital Video Recorder (DVR) which helps to digitally convert the analog data stream to digital video format.
In such an Analog CCTV system, the Coaxial cabling used for data transmission can only send information in one single way.

Importance of Choosing the Right Networking System Platform
Although a lot of the digital video surveillance system design and buying guides available out there in the market suggest that the first thing you should be looking at is the Dome, Bullet, Solar Powered Camera or PTZ (Pan Tilt Zoon) camera vision hardware, there is however, a much more critical step or decision that you need to be able to make before you look at any IP Security Camera hardware items, product accessories or any software, which is deciding on which PoE cable networking system platform to build your CCTV Surveillance system on, ie. whether to use a Centralized or a Decentralized platform.
There is a much important decision that you as a customer need to account for and make when deciding on the best IP Security camera system and DVR & NVR recorder to shop for.
Typically when you need to implement an IP video security surveillance system, the list of components and related products you require to order typically for a centralized video surveillance system includes
1. Camera type
(Type of categories: IP, Analog, Dome, Bullet, PTZ (Pan Tilt Zoom), Solar Powered CCTV, Wireless CCTV, Night Vision Camera, Indoor, Outdoor Camera .. etc)
Brands: HikVision, Panasonic, DaHua)
2. Recording Lens for wide field of view coverage
3. VMS recording and Log view management Software,
5. Multi-Channel DVR recorder, NVR recorders or Network Attached Storage (NAS) recording devices
6. housing (for Outdoor),
7. Network & Power Cable & Data transmission cables,
8. PoE Network Switches
This is in contrast to buying a new decentralized system, which requires you to buy fewer system components, such as
1. Cameras (Dome, PTZ (Pan Tilt Zoom), Bullet), 2. Lenses, 3. Attached Storage, 4. PoE Network & Power Cable
Difference Between Decentralized & Centralized System
Which Network system you decide to go with, either Centralized or Decentralized with will effectively determine how much you need to financially spend upfront and over the useful life of the Cloud-enabled CCTV Camera system
So what’s the difference between the two wire Networking systems? We can see the key difference is a decentralized surveillance system is comprised of IP cameras that have the following functionality
1. Video management software
The Video record management software technology is pre-installed in the Dome PTZ camera in camera DVR storage
2. VoIP phone functionalities
A Wifi VoIP audio functionality allows the Web camera to easily auto record, send and receive phone calls to any kind of telephone, whether it’s a Fixed landline or mobile phones (via a mobile app application) without the help from an external computer
The camera body enclosure has a rugged weatherproof custom design which allows them to be deployed straight out of the box without the need for the care protection from an outdoor protective housing.
Decentralized IP Security Camera System
With the decentralized CCTV camera system, the Dome or PTZ cameras themselves are equipped with the NVR feature capability. This means that a central NVR is not necessary and eliminating the need to pay for a costly licensed video log management app software.
As all the processing hardware & software is built into the camera, it allows the cameras to have the intelligence to independently perform all critical video management functions such as
1. Video analytic processing service
2. Motion Event triggering of Video capturing
3. Video processing of the Alarm event detected
4. Storage Management
In addition, there’s a new Megapixel IP camera technology available in the market where all the logic entirely is resided inside the CCTV camera itself
By installing the video management software at the IP camera itself, the video is able to immediately processed at the source, rather than needing to transport the data at a central NVR for processing
This allows the PoE CCTV camera to efficiently work to package the video as packets are just like an NVR. In addition, it can also store the video sequences as ready to access files format directly to any kind of digital storage memory, SD card, Hard disk memory drive, Removable flash or NAS (Network attached storage)
1. Directly Viewing of Video Recordings from the Memory Storage Media
A key benefit of such a decentralized CCTV system is that the camera can function as a recorder and essentially record usable Video footage directly to any form of memory storage formats such as Micro SD card inserted in the camera, External storage hard disk drive or Network-attached Storage (NAS)
Some of the many benefits of adopting a decentralized network IP camera is that end users can enjoy direct connection to an external Ethernet cable, Hard disk memory or Network attach storage (NAS) unit and start recording terabytes of high definition (HD) resolution megapixel video at the camera without the need for consuming any network bandwidth at all
This recording of usable high-resolution video log allows the video footage can be accessed and viewed straight from the memory storage device itself, either Locally or Remotely via a network wire cable and an internet browser.
Utilizing a free of charge client management program, end customer can have the power to easily connect & access the stored video work logs and efficiently perform time & date based event searching.
Such a decentralized PoE cable network system helps to completely eliminate the need for a central NVR & effectively frees you up from the costly ongoing video management software licensing costs and server hardware service requirements.
2. No Video log management software licensing costs
With a decentralized network system, there is no requirement to account for additional Video log management software licensing costs as the software is already installed in the cameras.
Each of the camera in a decentralized system is able to effectively operates independently like individual DVRs on the PoE wire network.
This means that there is no single critical point of system failure, as each camera can independently work & record to its own individual storage media located inside the Megapixel camera.
The storage recording media can range from either an internally installed SD memory card, External hard disk drive, or to a Central storage devices such as NASs or a Windows or Linux based computer.
In the event that one of the CCTV cameras lost its network connectivity or there is a hardware malfunction on the storage media, the camera will continue to work and buffer the video internally until reconnection is made
In addition, PoE CCTV Cameras can be programmed to instantly perform sending of motion event triggered an alert notification by sending an email SMS or making a phone call that contains a pre-recorded detailed message relating to the incident and a suggested course of action to take.
The pre-defined motion Event trigger can be based on predetermined parameters
Centralized IP Surveillance Camera System
In a Centralized CCTV surveillance system, the IP camera is able to perform basic video capture, record & processing functions, such as
1. Video footage encoding
2. Basic video analytic
3. Event triggered video recording
However, it is important to note that all the Video record processing work, Alarm notification event, and Storage management is handed out by an NVR (ie. Network Video Recorder ), which usually consist of a Central PC computer which is pre-installed with a licensed video log management software package.
With a centralized system, all the processing has to go through the NVR first in order for the customer to enjoy full functionality.
If for instance, the CCTV camera recorded straight to an external storage media, be it an SD card, Hard disk or NAS without a central NVR connected to the same network, work users will not be able to perform intelligent time and motion event-based searches on the recorded video footage.
The lack of camera processing services functionality in a centralized network means that all video log data has to pass through the NVR connectors first.
When it involves recording to an attached storage media for the purposes of archiving storage, this can only happen once the NVR has complete the footage data processing.
It is only after which users can carry out meaningful searches on the archived video log using Time, Day and Event input parameters.
Disadvantages of Centralized IP camera system
In a centralized IP camera system, the video data captured has to be 1st processed and packaged by the NVR before it can be searched and accessed. As all the video store data is required to be streamed to pass through a centralized point such as an NVR, it presents a potential resource bottleneck which can potentially cause Network and server resource overload to quickly happen.
This is particularly so when you have to search to get multiple CCTV cameras recording simultaneously in the high-resolution video
1. System Dependency on NVR
The entire decision-making process and overall success of the surveillance system deployment depend on the central NVR because in such a centralized CCTV system the NVR handles all the motion Event triggers configuration, Data Storage management & administration, and Video post-processing.
In such a setup system, video data is constantly being sent and received over the information wire cable network between the CCTV Cameras and the NVR
In the unfortunate event that the NVR or any wire cables malfunctions, the entire system will cease working.
2. Hidden Licensing Cost of Video Management Software
The video management software license in the NVR of a centralized system is normally charged on a per Camera basis.
This means that there is an added cost during orders for each Camera installed to the CCTV system.
In addition to the existing NVR server license cost, some Video management software company also charge a yearly software maintenance fee to receive for software upgrades.
