Knowing The Shift Toward Network-based Video Clip Surveillance In Asia

Threats of security continue to pervade the world-wide market place because September 11

. Bombings and threats promising mayhem and destruction had led into a surge in investments about safety and surveillance programs. This really is fueling the modify in how we seize, retailer, and keep track of video clip.

As per Shivanu Shukla, an business analyst at Frost & Sullivan "There has been powerful interest in being able to remotely keep an eye on surveillance cameras, run video analytics, and integrate surveillance with other physical safety systems."

Shukla notes that network-based video clip surveillance techniques are becoming popular. Frost estimates the video clip surveillance market to grow from $992.1 million in 2006 to $3956.7 million in 2013.

Analog vs. digital

Analog video clip surveillance programs consists of analog cameras connected via coaxial video cables to multiplexers and in-turn connected to monitors and key boards. But what happens when the area that needs to be monitored is a significant distance away and there may be a need to record 7x24?

Network surveillance solutions allow existing analog cameras to be connected into a video server, which can be connected to the network, and monitored by any computer that is on the network, or the existing control room.

"Storage of the video clip can be done by network video recorders (NVRs), which can be anywhere on the network, as opposed to digital video recorders (DVRs), which need to be placed close to the cameras or the switcher/multiplexer. In the whole network surveillance solution, network cameras are used to connect directly to the Internet protocol network, without the need for an external encoder," says Shukla.

Video surveillance deployments in Asia are mostly analog based mostly due in part to the market's price sensitivity. But that is changing as the security threats still remain high on radar of both commercial and the public.

Kiran Kumar, a Frost Research Associate, notes that government and transportation sectors are spearheading video surveillance deployments, with large projects for airports, city surveillance, and also other critical infrastructure surveillance.

"Fast developing physical infrastructure such as airports, seaports, highways, and rail networks is a key driving force for the powerful adoption for video surveillance techniques," says Kumar. There are three main factors limiting the continuing growth of analog video clip surveillance methods:

Cost: Set-ups and installation costs of traditional coaxial or fiber-based cabling for analog video clip methods over large areas is exceptionally high. Large-scale projects for city surveillance and monitoring of harbors and ports take a significant role in effecting change to network surveillance.

Scalability: Despite DVRs having improved the recording quality of analog cameras, there is even now the physical restriction of its installation near the analog matrix.

Flexibility: Integration of analog video clip surveillance systems with other methods can be cumbersome. Analog surveillance systems are limited to centralized video clip analytics, which requires additional hardware, cabling and is difficult to scale.

Benefits of network surveillance

Digital technology is helping extend the capability of surveillance beyond what can be achieved with traditional methods.

Technology now allows us to keep track of an area from any location in the world in real-time without any significant investment.

Storage of video clip can be done on NVRs that can be anywhere on the network. How much video we can keep digitally is limited only by the sum of hard disk space. And because the video clip traverses through the network, backups can be done remotely.

Scalability of network surveillance methods is easy and inexpensive. Network cameras can be connected to the network without rewiring.

With network surveillance systems, intelligence can be distributed either directly at the camera or encoder, or centralized on the NVR or a separate server.

Network surveillance programs are cheaper to build and maintain with reusability of existing Ip network infrastructure, highly scalable with little incremental costs, low maintenance costs, and ability to reuse existing legacy surveillance cameras along with display and monitoring equipment as key factors for adoption of digital surveillance techniques.

Limitations of going digital

Not everything is bright and rosy. Due to its dependence on the network, security teams will need the support of the IT department.

"The key challenge to adoption is to get the security and IT teams to adopt network surveillance. Existing network infrastructure makes the proposition of network surveillance stronger. However, organizations where such infrastructure is less developed would be slow to move to network surveillance," says Shukla.

He concedes that network surveillance adoption is changing the dynamics between the safety personnel and the IT teams within enterprises, hindering its adoption rate. The introduction of network surveillance implies the participation of the IT division in protection matters.

"Security personnel are typically more conservative and not open to major changes in their environments. Network surveillance adoption would depend on the successful interactions and communication between the two teams within an enterprise," notes Shukla.

Although Frost & Sullivan expects the trend towards network surveillance to be powerful, adoption of analog system will will begin to grow as well, albeit slower than network surveillance deployments.

"While remote access, scalability, and distributed intelligence are the key drivers for network video clip surveillance, price, perceived reliability, and conservative nature of protection teams to alter and adopt new technologies will hinder adoption," says Kumar.

Traditionally, cameras have been the point of entry for vendors into the market place; subsequently their offerings include DVRs, NVRs, encoders, and software, together with switchers and multiplexers.

more and more , due to the emergence of network surveillance solutions, there may be an effort from vendors to approach the surveillance solution from the NVR or DVR front, by offering better management software, virtual matrix methods and video content analytics as a solution package.

As traction for network video clip surveillance picks up in Asia Pacific, providing complete end-to-end surveillance solutions is expected to become a key to succeed in the market place.
