CCTV

See the World Differently

CCTV Systems

A CCTV (closed-circuit television) system allows the use of videos cameras to monitor the interior and exterior of a property, transmitting the signal to a monitor or set of monitors.

More and more of us are switching on the benefits of CCTV security systems. In the UK it is now estimated that there are more cameras per person than any other country in the world.

CCTV is a cost-effective crime prevention tool that also has some other useful functions. When staff and customers know that they are being monitored and their actions digitally recorded this serves as a strong deterrent of any wrongdoing. This is particularly beneficial when one considers the high crime rate in South Africa. A CCTV system is a popular tool used in many industries today because of its reliability and affordability when compared to a stand-alone guarding service. Cameras do not fall asleep, arrive late or make demands. However, a CCTV system can become a very effective tool when paired with an offsite monitoring and armed response system to reduce the risk of, and efficiently react to, suspicious activity or even break-in attempts.

Analogue Systems

Why Analogue:
Cost
Simplicity
Technology is getting slightly better
Cameras on an modern analog CCTV system send their video in the traditional base band format over coax or UTP cabling back to a digital video recorder (DVR). Here, video is digitized and stored on hard drives. Most modern DVRs are a network device, and as such can be accessed remotely from the LAN, or with the proper configuration, from across a WAN or the internet. There are no tapes to change. Video is kept on hard drives, typically on a FIFO basis so there is always a rolling video archive of the past X days. So, despite the fact that video is being transmitted from the cameras in an analog format, live and recorded video is still available over the network.

IP Systems

Why IP:
Ease of Installation
High resolution
Intelligence and Analytics
Less Equipment
Higher security
IP video cameras broadcast their video as a digital stream over an IP network. Like an analog system, video is recorded on hard drives, but since the video is an IP stream straight from the camera, there is more flexibility as to how and where that video is recorded. The DVR is replaced with an NVR (network video recorder), which in some cases is just software since it doesn't need to convert analog to digital. Video footage can then be stored on new or existing network RAID drives as directed by the NVR software.
  • Video Quality

An IP camera excels in capturing high definition, megapixel images. The maximum amount of pixels that can be created by analogue cameras is 0.4 megapixels, and 10 megapixels by IP cameras. Just like pictures taken with digital cameras, the more pixel the better image quality. 

  • Installation of Security Cameras

Analogue cameras are easier to install because they require no configuration and network knowledge, while IP cameras require some networking skills for small installations and more technical skills for enterprise size installations.

  • Cost of Implementing an analogue security system versus an IP security system

IP cameras are more expensive than analogue cameras. One of the main reasons is that IP cameras have higher megapixel. But it is important to note that high megapixel means that they can cover a larger area and can take the place of several analogue cameras. So in this case, IP cameras can be more cost-effective.  

To sum up, both types of cameras work well in either commercial or residential security. The IP camera’s advantages are high definition and enterprise wireless application, while analogue camera’s advantages are more practical, easy to operate, install and cost-effective. Whether an analogue or IP is best for you it all depends on the security needs of your business.
