Modern Security CCTV Technologies
A CCTV security system is set up with cameras that capture video and images and then transmit it to an authorized person through a networking system. Currently, most individuals and businesses are using this technology for surveillance and monitoring purpose due to security-related terms. Also, CCTV can be used for other applications like
• Crime Prevention
• Public Safety Applications
• Management Tools
• Post-Event Evidence Tool
• Traffic Monitoring etc.
In last few years, this security system technology has taken a significant part into surveillance and monitoring terms. In the present there are mainly two kinds of security CCTV technologies, as listed below:
• Network CCTV technology
• HD Analog technology
Network CCTV technology
This technology is also known as IP (Internet Protocol) technology. A Network CCTV camera or IP camera digitalizes and processes analog images and then sends the information digitally to a computer over the Internet connection just after encoding the data internally. Generally, these cameras have either CCD or CMOS sensor, and are embedded with web servers. Footages can be accessed over an IP network like internet, intranet, LAN, or WAN. Just a standard web-browser is sufficient to view the footage from any location. This technology allows the user not to connect the camera with a computer to operate. Cameras have their IP addresses, and these can be connected directly through wired or wireless network. This technology also does not need cabling infrastructure.
• This technology can achieve high-resolution images and provide excellent images.
• Zooming in x2, x4, or even x16 can produce clear playback footage.
• Data cable is the same for video transmission and power supply. No other cable is required.
• Cameras under this technology are easy to move or replace.
• It allows a variety of data storage options including redundant and remote storage.
• IP cameras give inferior performance under low light condition.
• If the network goes down, then there will be no live video recording because it is mainly dependent on a network system.
• There are delays in live videos like there can be 10-20 seconds delay if all cameras are being watched with higher resolution in real-time.
• The installation process takes much time and planning. If the installation is not planned correctly, then it can suffer from latency, delays, and missing frames.
• Ip cameras need much storage as it records in high definition format.
• The initial cost of setup and then maintenance, both are much more than other CCTV systems.
The significance of cabling architecture in these technologies:
Cabling architecture is the complete system of cabling and associated hardware. It provides comprehensive telecommunications infrastructure in security CCTV technology. In both Network CCTV cameras and HD analogue cameras, cabling can be used; mostly used in analogue CCTV systems. But modern HD analogue cameras are no longer measured in TV lines.
With cabling architecture, there are a few pros and cons.
• It provides real-time footage without lag.
• It does not allow the delay in live footage.
• Easy to install.
• Less in cost.
• Accessing all the cameras at the same time will never be hard with cabling architecture.
• It does not allow for a wide range of using the area as it will need large wiring.
• It cannot be accessed from anywhere while the wireless system is helpful to access footages from anywhere.
• Hiding the wires after installation is difficult as it can be messy.
While with all these pros and cons, cabling architecture is the most commonly used architecture over CCTV camera issues for years. The wireless system is modern technology that is being used nowadays, but for small household use or office use, this architecture is undoubtedly significant.
